HaLRGB image of M81. I really needed more blue data for this image. I have twice as much red and green as blue, and more Lum would be useful too, but my prospects of imaging any time soon, seem remote to say the least. Overall I'm happy with it, but my galaxy processing definitely needs more improvement.

A fine image Brian....I also find myself very often short of blue I guess generally its the last filter for me to move onto...

Thanks Peter. Depends on the moon phase for me. If it's a new moon I will do Lum first, otherwise it's RGB, but blue is generally last in line. It's just easier to put them in the LRGB order on the filter wheel.

It’s looking good so far Brian. At least you can do RGB! I can’t do it with the light pollution I have here in my Bortle 7/8 and have to use my OSC with an IDAS D2 filter to get RGB broadband. For the mono camera I limit myself to narrowband and forget about RGB

On a good night I can get 2 minute subs on my ASI 1600 in RGB, and 1 minute with my Lum filter. If the seeing is excellent, with no moon, which is rare, I could push it to 3 minute subs with the RGB.
