M104 - The Sombrero Galaxy in Virgo.

My first completed image in 2 months...Late winter/early spring has typically been bad AP weather here in Austin, so clear nights haven't been many. I did manage to eke out enough frames on this to call it done. I literally shot 4-5 frames a night on it with high clouds to complete this one.

I have been trying to shoot this galaxy for a long time but due to its declination (-11 degrees), I don't get a good view on this one and each year I ended up missing it. This time I was determined to keep at it. I probably pushed it too hard but at this point, I am quite happy given the precious few color subs I got to work with.

Masked out deconvolution artificats in the halo. Reduced the effect of HDRMT that reduced the halo too much.


Reprocessed from scratch, Threw out few more subs. The seeing just wasnt great to tighten things up. Once I push it , it falls apart. So just pulled back the stretch, stopped with heavy decons and masked it as much as I could. I will try get more subs next year if the weather cooperates.


One more variation. Cannot really get to where I want it to be. The data is just too soft to push .
