Description

I reloaded the first image of the Iris and added new subs with my 80/560 Astroprofessional ED refractor...

More colors with the "small gun" and still the same amount of details with the big one.

DATA :

APM 152/1200mm : same as previous (34 x 105'' + 4 x 140 + 4 Ha ... @ 3200iso) ;

AP 80/560mm : 16 x 150''...

D VERSION : inspired by the shinning colors achieved by our colleague David Dvali, I re-opened my own rendition of the Iris and tried to check how much more I could get out of it : is it too much ?

C VERSION, same with 4 x 0-III (450''@ 3200)
