I have an early start on galaxy season, largely due to a tree beloved by people who hate astronomy and probably puppies. Some of these people include my wife and neighbors who are also close friends, so that healthiest of trees is staying.
I'm in a Bortle 8/9 zone and eyeing integration times upwards of 40-50 hours per galaxy target at f/7 (C11 Edge) with my mono camera. Much of this will be luminance. 20 hours of luminance on M81 looks very promising. I'm looking for any edge I can get. I've come across the Chroma LoGlow filter and I was wondering what others think of it on broadband targets like galaxies? Is there a noticeable difference (improvement) between this and a "normal" luminance filter?
I realize no filter is going to turn my location near Washington D.C. into a Bortle 1 paradise. I know the best filter for broadband is called "load observatory into flatbed truck and drive 5 hours to the mountains." Perhaps one day. For now, I'm looking to maximize what I have where I have it. I'm looking for even a small SNR increase. This isn't necessarily to reduce integration time. I have an observatory and image from a warm house while streaming movies so an additional 5 or 10 hours luminance isn't a big deal. I just would like the best data I can get going in that I can get from where I image.
