2" Amici-Prism with 2" nosepiece and clamp

Inside the nose piece behind the M48 filter thread the diameter is 43mm. It is matt black painted and is made with grooves to minimize reflections, it is not a T2 M42 thread.

For highest magnifications, we offer Baader 2"/90° Astro Amici-Prism with BBHS ® coating # 2456120 which is made for highest magnifications. #2956152 instead is a high-quality Amici prism and better that many prisms which are included in telescopes, but it is not made for highest magnifications.

The Astro Amici Prism # 2456120 is suited for high magnification, while the 2" Amici # 2956152 is not. Standard Amici-prisms (like spotting scopes, too) are good for magnifications of up to ca. 60x-100x; of course this depends on the quality which you expect. This is the range of magnification suitable for terrestrial observations, where air turbulences usually prevent higher magnifications. Especially stars or bright planets in the center of the image show imperfections clearly. The Astro-Amicis allow for much higher magnifcations - the magnifications which can be used astronomy. This is not a problem of the telescope which you use, but of the optical design of the prism. There is an edge going through the middle of the prism which can cause reflections, and also both sides of the image need to be at the perfect angle. There is of course no strict limit for the magnification, but somewehere between 60x and 80x is a good limit for standard prisms.

The 2"-nosepiece of the prism has got an M48-thread for 2"-filters, so you can attach 2"-filters in front of it. The nosepiece is removable and also attached with an M48-thread to the housing. The eyepiece clamp is not removable. I'm sorry, but we can't publish CAD-drawings of the housings - there is too much "Cut&Paste-Copying" in the times of the internet.

This 2" Amici has got indeed a clear aperture of ca. 38mm, so it should work quite well with your eyepiece. Unfortunately, we do not have the data about the light path at hand. The nosepiece on the telescope-side can be removed, the housing has got an M48-filterthread, too. Only the eyepiece clamp can't be removed.
