I'm new here. After many years reading your posts, I finally decided to create an account on CN.
So here it is. I'm the recent owner of a SW mak 127 (FL 1500, f/12). It came with a 2in diagonal. I also have a 1.25in 32mm Celestron Omni plossl EP, which I can use with this scope using the 1.25in adapter. This EP has a AFOV of 50 deg. as far as I know. This EP was mainly used on my SW 130 reflector before the mak.
I'm not an expert, but I know that the f/ratio of this scope makes it limiting regarding FOV when using low power EP. So my question is the following: If I'm using a 2in EP, 32mm 70 deg. WA, will I be able to use the whole FOV, or I will be limited by some vignetting? The EP in question is the Orion Q70 32mm.
In short, would I gain any improvement with the Orion Q70 32mm (2in, 70 deg. AFOV) vs the Celestron Omni plossl 32mm (1.25in, 50 deg. AFOV) as far as FOV is concerned?
I know this may be tricky to answer based on theory/calculations. Anybody has experience with low power, WA EP on this scope?
Any help is appreciated. Thanks in advance.
