- Astromania 2" 2 inch to M48X0.75 Adapter for Telescope Eyepiece Lens

Really well made 2” M48 telescope t-ring adapter. Anodized finish is tough and hasn’t scratched while using it. The threads are smooth and go on and off easily. I would buy them again if I ever needed a second one.

Well made and works just fine.

The white box it came in said 2" T-Adapter, so I was worried it was a 2" nose piece with M42 threads (T-Threads). Fortunately inside the box is, in fact, a 2" Nose Piece with M48x0.75 (2" Filter) threads. The part's quality is very good with no flaws in the finish and perfect threads that confidently hooked up my heavy binoviewer, 2" diagonal, and eyepieces to the back of a refractor. If you told me it was a Baader nose piece, I would (almost) believe you.

This appears to be a well made product and comes close to what I was looking for. I am using it to attach a focal reducer/camera setup to my triplet refractor. The most important aspect which is the thread specifications are accurate so it mates properly with my focal reducer and the barrel end fits correctly in the compression ring on my focuser so that is good. So why the downgrade? The description of product specifically states and illustrates the product to have a safety groove. The one I received does not. The barrel is completely flat. This increases the chance that it could fall out and damage over 2000.00 worth of imaging equipment. Like I say, it is a good product, but I really did want that safety groove.

This adapter allowed me to connect my Nikon D5300 to my William Optics Telescope. Works great!

I have a telescope that does not have a threaded connection for my astro camera, so this allows a solid connection.

This is well made! The male threads are just short enough that it'll thread into a ZWO OAG without contacting the prism. The safety groove is a nice idea, although if you've got a compression ring in your focuser it won't make full contact with the barrel since the brass strip would have to bend to match the taper on this adapter. Most compression rings can just be taken out temporarily if this is an issue.

This isn't a complicated part , it's just simple and easy. It does what it's supposed to do and seems well made. Great item for the price.
