Focal reducer for small Mak
Posted 26 March 2013 - 09:41 AM
I'm looking for a small scope that will be used for astronomy at night (mostly Moon & Planets, a little DSLR AP) & birding during the day.
I was thinking that a 90-127mm Mak would be great for the astronomy part and, with a 6.3 focal reducer, give me a wide enough FOV during the day.
I have a focal reducer that suited my old 8'' Celestron. will this fit smaller Maks too?

Is there anywhere I can see a simulation of the vignetting?
Especially for day-time viewing?
