How to build a helmet for the gods ? ..Well you take a O3 filter,a Ha filter and alot of time .. gheghe

This is only the O3 Data,its not much,but its a start. I choose to go for Bin 2x2,and a higher Gain,because the Celestron C8 @ F10 is so slow.

It really gives a boost..the O3 in this nebula is huge.This is only 26 subs it could be great later.
