LRGB M81 & M2

[Northernlight]

Hi All,

last image for the night. My first stab at imaging galaxies.  M81 & M2 take on 102mm doublet @ F5.6  (571mm FL).  Image is LRGB,   L = 10x 600s,  RGB = 10x 300s and camera is a QSI 683.

The image is a little heavy on the red/pink side of things as i had scrap a few of the Green and Blue subs due to clouds, planes and everything else that decided to photo-bomb the image that night, lol.

Lovely work. 

[Northernlight]

thanks all, very kind, but i think i need an awful lot more practice. it's a starting point to build on.

Very nice image. You are well on your way.

[ollypenrice]

Yes, well on your way. You can fix the colour balance in various ways. The easiest is in Pixinsight with DBE. Or, in Ps, you can look at the histogram in Levels and try to align the top left of the pedestal in each colour.

Hi olly, the biggest problem i had was that i lost a lot of green & blue subs. I'll grab some subs on the next rare event of some clear skies.

Olly is absolutely correct - less than 2 minutes in PS produces the version of your image below. All I did was neutralise the background and a bit of sharpening using a high pass filtered layer with a star mask.

With a bit more work I am sure you could improve it further

Hi Derrick,

That is a big improvement indeed. I'll try reprocessing the raw data and see where i went wrong. It's all good pratice which i desperately need. Many thanks for taking the time to tweak the image.
