M33 Triangulum Galaxy

[powerlord]

Still struggling with reference frames for new asi2600 - I've taken 100 bias now to try and even out the horizontal banding I was getting, but now the flats I took this morning with my light pad which usually works a treat have a bright bit in the centre - not much, but enough that they are useless for stacking - I end up with a big white blob in the middle of my stacked image... so again, I've had to process this with lights only.

I'll try again tonight and suppose I'll just have to not use this data as I doubt it'll stack well with another session if I do get tonights sessions flats right for it... but will try.

anyway - here we are - 140 mins of 5 min subs at gain 100. no filters other than IR window. EQ6r-pro and SW 200pds with baader mk3 coma corrector. Considering no reference frames, it's promising for tonight.

No sharpening or colour changing here - just a bit of noiseXterminator and some saturation.

That looks real a nice standout image!

thanks. it was a bit green, and last night I added more data and proper flats, bias, darks. So here is the final result. The best M33 I've taken so far for sure.

245 mins of 5 min subs, asi2600, sw 200p+baader mk3 CC.

tbh, I prefer the one above with the green tint I think though. thoughts ?

Here is I think my final image - after capturing an hour of Ha for it last night with final colour balance

Superb final image! It looks like the addition of flats and some Ha data has made a huge improvement.

Picture #2 is the best IMO.

First is green, the 3rd one is too aggressive in purples and blues. The second one is a bit too red still and could use white balancing, but i like it the best out of the 3.

you are right, still not right. here's v4
