Hi Jase
I used HOS for the Helix and it worked OK. I tried it some time ago on some other nebs with disappointing results, so I didnt bother again. Youve piqued my interest again though, ill test it with some other nebs. Perhapes the difference between reflection and emission neg is the key.
My filter wheel doesnt carry RGB and NB filters all at once, and swapping is a pain, especially with last minuite target decisions (and haveing only random clear nights, mutinight exposures, despite automation, can stretch projects to many weeks). But yes, a combination of NB and RGB would be interesting, not just Ha lum on an RGB (or the other way round). I dont see many (any?) full mergers between the 2, food for thought.
Cheers
Fred
