Hi Folks,
This is one I took on Sunday night. Seeing was quiet good for a change so a low angle target seemed like a good idea. Only could image this to the west of the meridian as it only just clears the roof of the Observatory.
Image is 20 x 5 min @ iso 800 with the 8" and 20D.
May not be the best M33 around but I think it came out very well considering how low it is in the sky here and what my other attempts look like!
Had to shift the color channels in PS as the red/blue channels didn`t line up by a few pixels, I suspect that`s caused by atmospheric refraction?
Image is cropped a bit and reduced to 50% for posting.
Comments and feedback always welcome.
cheers Gary
Thanks Mike, Chris, David, Mark, Emanuele and Ric!
Yes the 20D and the faster scope really help with targets like this!
Here is a higher res full frame version....size is around 500ks

Oooh that's nice. Superb actually. That is far better than many CCD images I have seen of this object which often show it very white with unpleasant pink patches of H11 areas. Also often very vague in form.
Yours shows the form, has the nice spiral arms in bluish tones yet captures the yellowish supermassive black hole area.
You gotta love these fast Newtonian Astrographs eh Mike? They certainly produce a wonderfully pleasing image.
That is a beautiful image Gary - SWEET!!
And, it's my turn to say that I love the way you've picked out the H-alpha regions in the spiral arms.
nice one
Doug
Gary, in your high res version where you have displayed the galaxy up and down (long ways) in the frame the arms of blues stars that move from the core out to the right actually appear to be also rising up from the centre of the galaxy in a 3D appearence - I haven't noticed this before in M33, excellent work.
