I still consider myself to be a newbie in this hobby .... but
Last night I was checking out the differences between single images of the veil nebula from a month ago while taking new images. I recently "invested" in a dedicated Celestron light pollution filter and Baader's highspeed F2 narrowband filter set for a Rasa. I image under a suburban sky dome, maybe Bortle 6/7. Seeing and transparency usually are good here in the desert (except during the monsoon season).
This first image was taken using a Triad filter at unity gain for 120 sec. with an ASI183mc. A masked stretch applied:
This image was taken last night under a lot of moonlight with the same camera but mono, ASI183m, and a celestron light pollution filter and baader ha F2 filter. Unity gain but only 60 sec. :
Contrast between the color camera and mono camera is remarkably improved. As for signal to noise ratio, the difference is a large factor. It seems like the jump in sensitivity from DSLR to one shot color is about the same jump from OSC to mono for deep space imaging. Another benefit of mono is how fast pixinsight rips through the load. After reading time and again on the benefits of mono vs osc I'm glad I made the jump.
F2 filters (o3 and s2 reveal great detail also) work very well. I have no experience with any other brand or type but these seems very sensitive. Using a fairly small sensor with tiny pixels combined with small filters (1.25") and a really fast astrograph seems like a very efficient and not to expensive imaging system.
I just got a hyperstar cable manager to remove the funky spikes but haven't tried it out yet.
