ASTRO: Work in progress M31 with G and B data added

this is HaGB with 25% of the Ha blended into B

i was only able to get 6 flats in blue tonight and that's what I used for
the entire image

the blue and green are 12 x 5minutes and the halpha is 21 x 20 minutes (7
hours)

so this is 9 hours of data total

I need to take real flats and work the 1 hour's worth of red data into it to
finish it up

The Halpha really makes the HII regions very prominent

shooting more flats and red next

Interesting!
I note the strong HII region in the lower part of your image. I've
circled it in the first image attached. I took this region in
Luminosity only last year. There was a very odd star cluster in that
region. It consists of arcs of stars around a bright hub. It exactly
matches your HII region though I don't really see nebulosity in my
image. It was designated as a cluster, I can't recall the name.
Obviously it is a major HII region as well. I've attached a cropped
version of my image with that cluster/HII region circled.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Beautiful image.

Was this taken with your A-P refractor?

Thanks for the comment George

I took this with my old-style FSQ106 and the IMG6303 with the Baader Halpha
and Optec IR blocking G &B filters

very special, especially to an m31 collector!

Richard, no wonder you could show the HII regions that well with 7 hours if
Halpha...
