ED80 with sw cc test

Recommended Posts

ive been wondering what would happen if i used my sw coma corrector with my sw ed80, well ive tryed it in daytime and looking at a tree about 2ml away i can see its increased my FOV buy about 15-20% so its acting like a reducer, i think its improved contrast and detail a bit when zoomed in,next test nighttime DS when i get some clear sky. has anybody else done this? even if its a waste of time its been interesting to find out what happens.  clear skys  charl.

I use the same one & I know the SW CC does shorten the focal length a bit by 0.9 not sure wot that equates to in % never used it for visual work.

Hi

A coma corrector (for a newt) isn't the same as a field flattener (for a frac) and aren't interchangeable.
