That's up close and and personal,

Liking the detail very much, the only criticism is the color,

Every thing has a mauve type cast, not sure what would be causing it .

Hope you don't mind I hade a very quick play in PI  and come up with this 

photo. but because it has already been streched I couldn't do a lot more to it.

I would run it through your software again and have another play,

It looks like you have some nice data there.

well done

Thanks Paul, 

The Color was actually my issue, you did magic to the pic, looks pretty good now. 
i dont know if that counts: i had to delete a lot of R and G channel (clouds and Dew issue on my secondary), Blue was about 30% more of the R and G. 
I will try and give it a second shot in PI. 

best regards,

Fantastic detail in the image.  If you are redoing in PI have a look at "photometric colour calibration" it is very clever and should be perfect for this.  You could also back off a little on the initial stretch.

Other than it being a bit too red in my opinion, fantastic work mate. You captured some lovely detail. That's all I can say. Nice job. 

 

How did you find the processing? I did my first M33 about 2 months ago and it took me a couple of weeks to finally nail the processing. I found it very challenging to coax the galaxy out of the stack

 

Cheers

Thanks for your kind compliments,

i can't say it was easy, but i don't know if it was because of lack of my experience or the complexity of PI. I had to re-do it twice from point zero because stretching out the fine details was very hard and always gave me a rainbow colors around the Galaxy. i used DBE instead of ABE to eliminate the problem.

clear skies!
