The 2.5x Luminos 2" Barlow Lens from Celestron extends the effective focal length of an optical tube by 2.5x. This telescope accessory features a fully multicoated optical path with four lens elements designed to improve color fidelity and transmit a field of view that is flat from center to edge. The eyepiece holder is threaded to accept 2" eyepiece filters and will accommodate 1.25" and 2" eyepieces; brass compression rings secure the eyepiece without damaging the barrel's finish. The aluminum housing is finished with an anodized hard coat for enhanced scratch and corrosion resistance.

Celestron 93436 Reviews
Worked great for my dobsonian
Works well, clear, just what I needed for my dobsonian. Most articles recommended a 2X, but for me, a 2.5X was better for views of Saturn. A little blurry for rings, but I think thats just my viewing conditions.
A well made and at a fair price Barlow!
A lot of lens for a reasonable cost
I tried a 3-element 2x Barlow, which was really heavy. In comparison, the 4-element 2.5x Barlow weighs about half as much but is built like a tank. Fit and finish are perfect. Lens comes with a black pouch plus front and read caps. In use, this lens seemed to be easier to use with my 12 Sky Watcher and Nikon D5300 than the 2x Barlow.
This appears to be awesome!
I ordered this early so when the Celestron NexStar SE8 becomes available, I will have it in hand ready to use. It is solid and weighs almost a pound. When I receive the Celestron NexStar SE8, I will update my review.
Great build high quality ....1 flaw!
Great build and the quality of the Barlow is excellent ..using it really brings planets , nebula and galaxies closer into view. The only downside it the 1 adjustment screw on the compression ring it has to be cranked down tight or the eyepiece feels loose like it might fall out ...it really needs 2 or 3 adjustment screws
After a few nights of skywatching, paired with our Orion XT8, I can say I'm happy with this purchase and would highly recommend it. The lens is surprisingly light but built well. The light quality is excellent. No issues threading on our filters. The compression ring connection is a great upgrade from thumb screws - no more screw marks on your eyepieces! I've attached one of our recent images taken with a Canon EOS R fitted directly to this lens with a Moon/Skyglow filter.
Brighten up the view
I luck up and found this unit used for sale for $80 from B&H just the best purchase.
Cant beat it for the price
Seems very solidly made. I bought two to stack them together for total 6.25x. Stacking them is pushing things a bit. With the addition of the camera its also a bit unwieldy on the telescope. Using them for imaging Jupiter and Saturn with my Skywatcher Flextube 250P 10 Dobs and ZWO ASI294MC Pro camera. In poor seeing conditions I was able to get the attached picture of Jupiter. After much time processing (still learning) I got the pictures of Jupiter and Saturn you see here.
