Top Customer Reviews: Barlow Lens 2X, ...
Has purchased immediately this Barlow Lentil 2X (Bysameyee Thumb, $ 26) and Orion And-Serious 7-21mm Zoom Eyepiece ($ 63). Using neither an immediately spent out of a true potential of a StarBlast: the coverage of Saturn was clearly visible partorisca mine 4 old year and can faintly mark out of some shots on Jupiter. The data has had the moon of neighbourhood in bylines among some two planets and is gone in the city has contaminated light, was VERY SATISFIED with some results. Some boys have been excited reasons easily could identify some planets. Of course, using both near was a better.
Has to that buy so only an accessory (any Barlow or Orion Zoom eyepiece has mentioned on) for a StarBlast, goes with a 2x Barlow Lentil. Using a Barlow with StarBlast 6mm eyepiece has given one main view (of a Zoom eyepiece can zoom to 7mm, any 6mm). This in spite of a question with a 6mm is that of then has such the small field of view, was sometimes last to find an object like these stellar objects constantly movement and also kids sometimes attack to a discharge (also a finder of the red point is not like this the friendly user like the Telrad, but concealed is not also of the question) to the equal that has had to trust 17mm to zero in in an object and transmission behind to a 6mm. But of then I have small boys, has been hassle to change behind and advance. So that it is where Orion 7-21mm that the zoom goes in. Wow! Like this convenient to find things when they move out of view, any I still needs to refocus during a zoom. It was also extra entertainment when some accesses of moon of whole neighbourhood in a 21mm and some boys can ZOOM to a 7mm his to look in some craters in detail. They have had the explosion! If calm only use a Zoom Eyepiece without a Barlow in a Starblast, any volume to see the big extra objects, but is well, can still clearly was the coverage of Saturn and grieve the shots of Jupiter.
Finally, highly recommends to take so much a 2x Barlow and Orion Zoom to spend was all that a small but a lot StarBlast the discharge has to that offered! I any one need the big discharge in the city has contaminated light to inspire some girls after all! StarBlast With a 2x Barlow and Orion Zoom give all a consolation, friendliness of girl, and the potential of astronomy requires.
P.D. With which try to remark some more brilliant galaxies (Andromeda) and another Messier the objects will update my description.
Top Customer Reviews: SVBONY 2X Barlow ...
A tez of this product, organism of metal and everything, is very refined compared with a plastic organism that comes with Meade. Mina untrained the eyes can not detect visible aberration in this QUICKLY Barlow. It contrasts, a Meade Barlow gives very obvious to the chromatic aberration when tried so much Barlow in Cosmos FirstScope as well as in Polaris 127.Q.
Meade IS a name of the mark has established. Like this the comparison weighs to plot in my same alcohol although Polaris is in Meade low-final.
Update: I actuate since it uses this QUICKLY in the much better telescope SkyWatcher S11600 Traditional Dobsonian 6-Inch (White). A scope collimated the parabolic mirror provides the clearest images in a verge of field to see so that it is easier to evaluate quality. I stack a 2x Barlow with one 20mm Kellner of one FirstScope and compares with one 10mm Plössl that comes with SkyWatcher. FirstScope eyepieces Is not also so SkyWatcher east; stacking two optic the together elements is generally worse that a piece of a same focal period. Even so, a Barlow the combination compares favorably. (A picture of Jupiter and his four Galilean satellites are taken with one 4mm of QUICKLY Telescope Eyepiece has Posed Aspheric 4/10/23mm 1.25' Wide Angle 62-Deg Fully Coated for Astronomical Telescope and one 2x Barlow in FirstScope.)
A Quickly 2x Barlow was very useful in me especially to use this tomb powered eyepieces p. p.ej. A Gosky 32mm and these sets of eyepieces Gosky 6mm 12.5mm 20mm. M shouted this morning approx 1:30 I AM and could not return to sleep and decided to walk out of my back step and cual saw was so Saturn and Course with a Moon approx 30 titles (i.et. Of a horizon in a Moon) poses in a westerly. I have decided to take my Meade 90mm AZ Telescope of Refractor and voice these planets. It was surprised really, is some first times have not seen never Saturn and his meshes that it uses each a eyepieces mentioned earlier and more than all using this 2x Barlow Dulcemente to take some so of the next planets that can see it so much although it sounds a long way. I have had also the look well with a longitude of March and was all excited in my cases by prejudices he down.
Does a bit those that the nights have seen also Jupiter those uses this 2x Barlow Dulcemente and was surprised also with so many details to see some groups in Jupiter and viewing 4 of the moon of Jupiter. It was able to see more clearly with this Quickly 2x Barlow that a a which is coming with my Telescope.
Some critic goes to complain that is blurry probably his chair/his failure for mishandling or can be the defect of manufacturers , but beg to differ how 2x Barlow this is coming with my Telescope is not also like this Quickly 2x, very clear and width well quite that sees that it uses my eyepieces.
IS very happy with this element and will recommend in any newbies in that likes him a challenge to be an astronomer of amateur.
Buys again, and recommend it.
Does very well in my telescope without glare or light scatters detected, highly would recommend this in any one that looks for the quality barlow without breaking a bank.
draw and tez Well. Any complaint.

Included IS an image of the tree 3 low streets that use a 20mm slow.
Could not take of the a lot of luck out of a Barlow slow, when look through just a lentil with my eye can see an image well, but to attach he in my telescope and attaching a eyepiece voice at all but black(still when it signalling directly in something like the brilliant light). This can be been due to my experience of pauses even so, as I am not that it lines that experience against a product at all.
Has opted to spend more for the ' adapter and eyepieces of the small better quality, but is not in the estimativa tight, only cheap, lol.
when doing some view has not imported what magnification, all have to think is
marks of object of the manufacture. I have taken these lenses in my work under low magnification.

Top Customer Reviews: Orion 08711 Shorty ...
The complaints against this product are probably because of a slightly big eyepiece beginning. Probably to accommodate the widest variety of eyepieces and components an on-sized the beginning can cause light misalignment of eyepieces and creates the small quantity of astigmatism. This is not perceivable or problematic with visual use, but can cause the yes used problem with photographic or another squad.
Has tried to use this Barlow to augment magnification in the camera of scope/of the guide and a resultant astigmatism was annoyingly perceivable. With the big plus eyepiece or alignment of the barrel of the camera could be improved. I suspect some lenses used is excellent and no a cause of an astigmatism.
IS always possible for any one to take the sense that is not directed I supposition, so he th the vendor wants to exchange this will be happy to try again. But if that is to say it likes him to him one duplicates the quality is, would not purchase this and I can not recommend.
A photo in my description is without a piece of extension and without the mountain of special camera. I want to aim that my scope and to the lentil is house . Quan Attaches a piece here a house is bad still after using a telescope to adjust.

Has been once varied, using it partorisca vary a discharge was astonishingly easy. Some instructions really have not said anything roughly regulating a secondary mirror but this is to be mention in another description, one takes a point in a centre of a mark of centre in a primary mirror.
If a costruttore is not that it goes to properly vary these, would not owe that cover some rays of alignment and would have to that resupply instructions partorisca alignment.
A collimator has the variable brightness beam (1-7 and was), regulated partorisca turn the coverage in an end of a casing. In of the main powers collimation possible during daylight, this in spite of a beam takes distorted of more than the short line that the point of round besides one 3rd to 4th setting. In of the lowest powers have gone perfectly.
A beam is almost perfectly varied, with just a faintest the flange that looks in screen of white aim, this in spite of some ports of adjustment have been sealed up with hule. More daring would be likely diverse perfectly with the knife of hobby and the hand in bylines.
A collimator careers of the CR2032 battery that is comprised, together with the to adapter of 2 thumbs for owners of 2-thumb focusers.
Has taken a device averts and found some three rays of fixation that resists a laser was not even close to be dipped a same period. Also, they are not adjustable like outsides of a headline of the ray of fixation is covered with some class of the hule adhesive (this whole thing is not easy to take averts in all the chance).
In an end has takes so only a laser and reassembled the quite so that it could see by means of him and the use likes the traditional collimation device, which in fact quite done adds.
Pros: Brilliant laser, adjustable brightness is fresh. A construction of metal is solid.
Gilipollas: A laser is not varied, and there is no accessible way to regulate alignment. Ossia The waste of money unless calm wants to take avert likes it has done and arrival with the old plus fashioned collimator more the laser for yours other projects of electronic.
Top Customer Reviews: Zhumell 2' 2x ED ...
BUT wine without literature at all, neither is there any manual in a Zhumell put of web. Like this here it is some things has learnt in premiers of mine few days to use it.
ā Laws like him 2x Barlow in any telescope that takes 2ā eyepieces. With one 1 1/4 thumb adaptadora in place in a cup, also acts like this he 2x Barlow with any 1 1/4ā eyepiece.
ā Uses so only a black of inferior segment that has a lentil in him, can scrape he to a fund of the 2ā eyepiece and result the Barlow. This can not be done (according to which can say) with 1 1/4ā eyepieces unless has the 2ā adapter like Baader Hyperion Mark IV Zoom done. ( I have bought a Barlow mainly to do this with this zoom eyepiece, which yields the perfect row for lunar or planetary observations with mine 1200mm spent of focal period.) This neither can be done (according to which can say) with a can a big plus Televue Ethos eyepieces, reason an interior 1 1/4ā coverage paste a lentil. (It does not take that inner coverage in a Ethos eyepiece; I have tried that once and to lentil of mine very expensive has taken loaned 13mm Ethos eyepiece has FALLEN Is gone in The EARTH. Oops.)
āAnother Big Oops: I have taken last night garbled and in planting to take so only a thin upper 1 1/4ā adapter, has takes also a black thickness bumpy section down the, and has slipped so only a plus down 2 sections (money and black) to mine 2ā focuser, that thinks that could do like this Barlow with a Ethos eyepiece. He no with a Ethos reason a course of money of a Barlow does not return to a Ethos 2ā money of breakings of diameter. Worse, there was at all to resist has FALLEN like this ON By means of, PASTE The SECONDARY MIRROR And SLID ON DOWN to PASTE The PRIMARY MIRROR. He no a same deception! I still precise inspects to break now that it is a next day , and recollimate.
-With mine SkyQuest XT8i, a Barlow is one same likes any 2ā eyepiece in this I can not head to less than leaving in the width of the toe on the one hand of exposed money. Gotta Takes an adapter one of these days. But a part of money of this Barlow is quite long and has a bottommost section of black lentil that adds to his period for the total of 2 1/2ā sticking to a focuser, how is quite sure same without the insert a whole way. And of then 2 1/2ā of a Barlow total 4 1/2ā period is (usually) Inner a focuser, so only adds roughly 2ā (of a bumpy upper black section and perhaps one in lean black 1 1/4ā adaptadora section) to a period of eyepiece sticking on a telescope. Any bad.
Is resulted: I want a Barlow and like this far with mine 8ā Dob am satisfied enough that I have not spent more money for the main end a. Very easy to use like him 2x, and with the majority of 2ā eyepieces also like him screwed-in . To achieve 6mm big power (200x in my discharge) in combination with still chance he Celestron or Baader zoom 8-24mm eyepiece, INSURANCES BEATEN to change to mine 6mm Plossl, with his narrow lentil and so only 5mm of relief of eye!
Top Customer Reviews: SVBONY Barlow Lens ...
That is disappointing is a negative lentil has comprised in an assembly. It IS the 20 mm diameter, -125mm piece of focal period of mere, flat-concave, uncoated glass. No the cemented achromat or included coated. As some specifications of sales ('fully good coated', 'chromatic corrected') is risible, typical of those abroad fellow concealed says that that it wants to listen without any correlation in that some the words mean.
A -125mm the element is localised 22mm inner of a telescope focuser 1.25 inch eyepiece shoulder. A eyepiece the receptacle is 38mm spent a focuser shoulder. I use a Barlow formulas to compound what an effective magnification the proportion is in your instrument. A magnification will be M = f/(f d), where f = -125mm is a focal period of a lentil, and d is a distance of a lentil in a focal plan of a lentil. To achieve M = 2x specified for this product, d would have to be -1/2 of f, or 62.5mm in a focal plan. I do not see he so that it is possible with this tube that is lower, as they go real magnification to be very less than 2x.
Has still subjects with Venus and Course that is the blurs still will require to use the lentil by heart. Jupiter will see the colour of one 5 planet light groups, even so calm still necessity the by heart decent filter to see Jupiter the small more acute. The start of Saturn adds and some points are very has pronounced
-Works very well also the stack with another Barlow to take the good impulse with the most focal period very time, wide-field eyepieces.

Has bought SVBONY Barlow Lentil 5x of our tent and the nodes gives revises of Neutral product:If it is the 5 x, is the 5 x these products an image that is exactly a same measure...Using the 15mm eyepiece...As my two 3x barlows. Only no so acute and contrasty.
IS very sad for your inconvenience.it is can be a problem of a magnification of integer of a connection of Barlow lentil and telescope eyepiece,if one Barlow lentil' the magnification is big ,when install in a telescope, can surpass a valid magnification and a scene has remarked is misty result, is not to clear, as one Barlow to the lentil is not so main and better, Barlow lentil and telescope eyepiece is connected together for use, necessity to control a field of effective tax, for cleared an effect of observation.
There has 3 points in Barlow lentil:
Barlow lentil of the 1.un ,his function is not only to improve quality of image, but also for a consolation
2. Included the Barlow hurts very small in a imaging quality
3. To reduce an influence of imaging, Barlow careful selection in different magnification,In general, can do election of 2x in the.

Obviously, Angela English is the second tongue, but is the hell of the better plot that my French. And takings that bad. If you try to press magnification alln of a capacity of you scope, an image degrades by everything means of a quality of your scope, eyepieces or barlow. (Which are something has not known when has taken my first scope 30 years ago and something more the beginners do not know today.) To ensure him that my 'tests' has taken this to represent...This has tried to do some apples-in-comparison of apples... I routed lucido this response:
Angela,
Thank you for your worry. A scope has used... Has very... It IS, while I have said, he 120mm refractor with the focal period of 600mm. Under optimum conditions, is the maximum magnification is 240-250x. Compare my another barlows in your product only to see how yours has compared in contrast and acuteness. It compares the all in 200x likes him see tonight was a lot. That is to say, one 2x barlow with the 6mm plossl, one 2 3x barlows with the 9mm plossl and yours 5x with the 15mm plossl. Tan Sure enough, everything of one barlows would be 3mm eyepieces that would produce 200x magnification in my scope. Have Immediately of your barlow has produced the smallest image that an another 3. Quan Has exchanged one 15mm of your barlow in in mine 3x barlows, a measure of image was a same. One 15mm eyepiece with the 3x barlow products 120x magnification or means the maxima to be able the useful of my scope. And some comparisons have been done in this power. I conclude that yours 5x barlow is, in fact, he 3x barlow. It was also apparent that an image produced by yours era less acute and one contrasts was softer; one melts has not been so dark. Of your barlow, even so quite some same dimensions how mine another, is sensibly the lighter has concluded that probably it was the 2 element achromat more than the 3 element apochromat. Whcih Would count a quality of an image likes him compared in mine another barlows. And for an economic, 3x, 2 element barlow, is not bad in a prize. But it is manifestly any one that is announced to be.
Thank you For an offer of the 2 substitution to be able in, but while already have an excellent apochromatic a, the mediocre achromat would be of small use. In fact active Meade and GSO 2x achromats increasing powder. Yours would do 3. Supposing that you know your subject and that your provider for your 2 and 5 can barlows is a same, me assembla that it can have you took any mislabeled merchandise. Perhaps it have to run some tests of your own.
Better considerations,
Joe Lambie

Conclusion: Obviously, this company is doing is more to cure of these clients and provide decent squad like the would not doubt to try them again. A reason is amending this description is that I have read the bouquet other descriptions of the same barlow published here which there was not before I purchased it. I have read seldom descriptions of anything that involves a subjective test of a critical likes them almost each which gone to rack and of sea in 'l like' or 'has not liked him me', of an opinion, without an explanation of as an opinion has been arrived in. And when it goes in of the opinions, prefers my own. Which are the control on of 45 years like an actor that reads one the majority of the main atrocity quite the laws and the people has been involved with. At the end, that is persecuting now, for my own distraction, is is a current experience to see that it can be achieved of the clear-the place contaminated with minimum inversion; i.et. Down- it instruments of final. And I am having entertainment, which, in 73, flavours to have as much as poden in the daily base. For obvious reasons.
His magnification of the usable maximum is quite 260X.
But, bundled can big eyepiece gives only 65X.
While looking surface of moon, has wanted to more magnification.
In theory, 4X barlow lense would have to be ideal, using maximum potential, but no more.
In reality, included 3X barlens was out of achieving with his prohibitive prize.
(Considering a prize of telescope he.)
With a help of order of powerful amazon for prize (of low in big), has conformed this lense.
A prize is well and the specification of the vendor says is APO drawing, which are typically big quality.
But, had the very negative critic of another user.
In all the case, has wanted to to use all a potential of my telescope,
and bit a balloon and has tried he in me.
Felizmente, a result has rewarded.
IS the small long and heavy, but gives can of big magnification and quality of clear image only for $ 25.
Considering his focus of wonderful prize, give it 5 stars.
With
This lentil is the small long and heavy that easily breaks a balance of weight of telescopes.
(Then , negative critique of another user that has mentioned the focal period has his own value.)
With the balance of the weight has broken, a telescope takes unstable and the signal takes the small delicate.
Can of big magnification of the same barlow dulcemente, marks a worse problem.
Included One slightest movement of unstabilization also takes augmented,
And some beginnings of aim of a field to see easily.
Has 2 common roads to recover a balance.
1. Re-Balancing
- Loosen a ray these wineries one dovetail and adjusts one positon and tensing a ray.
- Chess balance, and if any one for the repeat again.
- No additional monetary cost but nettle.
( Would have to cross this procedure while attaching this barlow dulcemente.)
2. Attaching some magnet in a backside of a telescope, fuctioning like the counter-weighs.
- Purchasing some ways of magnet additional monetary cost, but take?, This lentil is such the subject .
- Attaching some magnet is much more convenient that loosening and re-tensing the ray,
and one OTA not having dovetail dish, that is to say an only road .
- In theory, in a same weight (how of this lentil) of the magnet will be required.
If any insurance in a pertinent measure of magnet,
purchasing multiple small magnets and adjusting a number of the magnet has semi-detached, is the sure election.
(The small magnets easily take sticked in the each another like the ray,
so handling the big number of small magnets is manageable.)
Has also the problem with magnification too big.
With 5X, is so easy to continue a maximum capacity of one optician of telescope.
(Maximum usable manification is usually 2 ploughing in mm.)
And after a maximum, the image takes blurred.
In my case, this barlow dulcemente and bundled can big eyepiece together has data quite 120% of a maximum, and the quality of image takes degraded the small.
Pro
In such the prize of subject, gives 5X the magnification can with well quite quality of image.
With the low power bundled eyepiece has attached in this lentil, the quality of image is quite well.
With the big power bundled eyepiece and this lentil gives 120% of a maximum magnification,
and the image takes blurred the small, but is happy to use all a potential of one optician.
Has detailed the view of a surface of Lluna is a lot satisfies.
IS well to maintain portability with drop of focal period, and taken big magnification, also, with this lentil.
Precaution
the stable mountain required and well-diverse finderscope (or finder of red point).
Listens like a telescope has taken 5X more sensitive with this lentil has attached.
Unstability Of a mountain and misalignment of finderscope taking has augmented also.
That is to say why weight re-the balance is of entity.
Conclusion.
A bit very time and heavy. Easily break it a weight-balance.
But after recovering a balance, gives 5X magnification with quality of good image.
IS the perfect access for short focal lengh telescopes, which typically lack of the magnification beat.
He Precise magnification main, but preoccupied in additional cost, to well sure recommends this lentil.
Left me only say that a quality is subjects further of the concealed had expected to arrive the to this point of prize.

02/03/2019 - Has to excuses, and is new in astronomy and didnt give a plus magnification, a lighter is lost.
