First Light with CCD CMOS LRGB M33

STILL NO FLATS...
Think i might try longer subs next time.

Went out last night to test the new camera and filter wheel , totally compatible with Astro Photography Tool as thats what im used to so quite happy with that lots more to do though including cooling the camera down last night to minus 10 and at the end of the session warming it up again to prevent thermal shock apparently , i think ive got thermal shock that i found 3 alignment stars , focused and found my target  all on first usage, although not framed well as it was getting late and i wanted to start imaging whilst still dark.I did do Flats but think i failed to save them properly , think i know for next time though.

It's a nice image but would be so much more with the addition of flats. I know it can be a pain in the neck trying to get your target centred after phaffing around with focus PA etc but it's time well spent. You should be really happy with the results and with such short exp. times too. 
Not trying to be critical, just some friendly advice  Do with it what you will

Yes, all that effort and expense but a seriously inaccurate range of brightnesses outside the galaxy. Flats are not that hard and they make so much difference. Sorry, but I'd feel like a liar if I didn't say this.

I'd also give your green channel a slight lift since the image tends towards magenta.

But, sure, there's a lot to like.

Looking great. But I would say in addition to the flats mentioned above you need darks to get shot of the amp glow to the right hand side.
