Celestron93326 Omni Barlow Lens, Silver, 2 x 1.25 Inch

This was a choice between the barlow lens and the $99 zoom lens by the same manufacturer.While the 8 t0 24 power zoom was very nice, I already has 6 fixed lenses from other sources. What I found is that the Barlow can take my 25x, 15x, and 10x lenses and they become 12.5x 7.5, and 5 power lenses. So, in actual use, I have 6 lenses 25x down to 5x...My scope is the Explore Scientific ED80,the low end one that sold last year for $129, which came with a 25X lens. My tripod is the Nano 3 for $119 by the same brand. This scope + tripod combination is not stable enough for the 5X use, and pretty shaky for 7.5, but both usable if you have enough patience. NOTE : Be very sure to slide the scope body up and down in the tripod clamp area ( with your Barlow and a 20X lens mounted for balance ) , until the scope stops slowly rising or falling off target. )If like me, and an amateur who wants a terrestrial / astronomical budget setup, I recommend this approach. Once you really enjoy the hobby, sell this , not losing too much money, and buy your better ED80...the doublet or triplet version. Keep your Barlow and a couple favorite lenses...you may find the scope itself is more important than several $300 premium priced lenses !

Amazing eye piece for the price. This is a very useful item to purchase if you are getting into astronomy as it basically doubles the amount of lenses you have in your inventory by just adding this piece on top. It is amazing quality, perfect size, and there is minimal loss in clarity for the everyday user. If you plan on getting into professional astronomy, this piece may need to be replaced in the near future, but overall it is an amazing piece!

Not a big fan of Celestron. Still have two silver top MIJ (15,26mm) eyepieces that are keepers but my only reliable barlow is an old Cave Optical so I am giving this one a chance. The barlow matches my silver tops quite well and appears to function well so far though it gets little use since I am mostly doing DSO's Barlows add more glass and in some cases dark images depending on the focal lengths. etc. By the looks of the reviews, I could be worse off in owning a back up barlow. For the price it appears a bargain.

A must have for beginners. Great price

This lens really helped me with the lunar eclipse this morning. I bought this lens just for this event and it did not disappoint I attached it with a 10x lens and used a camera mount.

I have not been in to this hobby before so I don't have a lot of experience with eyepieces but I can say this has indeed increased the range on my Zhumell Z130 telescope and having the lower element able to be unscrewed and attached directly to my 25mm and 10mm eyepieces is a bonus. It was also the only way for me to be able to get in focus using my DSLR and a T-ring adapter. Screw the lower removable element to the bottom of the adapter and I can take images with my Nikon. High magnification can be a double edged sword. Yes you get zoomed in but it makes things have an apparently much faster movement through the view. Be aware of that. It also means your spotting device must be very accurate or you will have trouble finding planets and other smaller viewing items. This has given me very sharp views of Jupiter, Saturn and the moon easily enough and allowed me to get DSLR images. Thumbs up.

I bought this for my Sky-Watcher Heritage 150p telescope. I wanted a light weight, 2x, fully coated, and a removable lens cell. This checked all the boxes.There are other brands that are the exact same specs and materials for a little cheaper, but I wanted this one due to the reflective exterior of the barlow tube. It will be slightly easier to see at night when I have it in the focuser to remind me that the eye peice is sticking out that much further, so I don't accidentally jam my eye in the eye peice or worse bump/catch it on anything.Since the lens cell is removable, I have effectively tripled my eyepeice collection for this telescope. I have the eyepeices, the removable barlow lens cell at 1.5x, and the barlow at 2x.I needed lightweight barlow because the helicle focuser is "suspended" due to the truss tube design of the telescope tube. This to to prevent excessive stress and sag on the focuser.

I didn't have to return it but really caused me an hour of frustration trying to figure out why the lens was capped and if the item was defective. Honestly, I have no idea how the cover popped off but I was tinkering with it very carefully for an hour. Celestron should have made this easier to open - I am sure there have been plenty of returns because of this. Once opened, no issues.
