NGC253 - The Sculptor Galaxy (WIP)

Hey guys,

I still can't this whole processing thing down who would've thunk it would be so hard!

Anyway here is a little image i am working on at the moment.

I have gotten about 9 hours of light data on this one. Currently working on the HA data. Conditions have been good and moon was low, i think a few subs with high cloud may have snuck their way in which I'll deal with in the final stack. 600 second subs at 200 ISO. I have also used DARK, FLAT & BIAS frames when stacking.

Trying to pay attention to the other end of the histogram now which honestly i did really let go. Previously i had always balanced the sky out but never thought about the stars. I used a G1V/G2V star in this and tried to work out the white balance and seemed to have some if not limited success. Hopefully i got rid of that darn red hue that was stuck in my images.

Any advice as always is much appreciated!

I better get onto it i have some perfectly clear skies tonight. Hope you all do as well.


Cheers
