Our second closest galaxy near the Great Andromeda galaxy is this one in Triangulum. 13 hours 47.5 minutes exposure time using the Hyperstar lens and the C11 reflector. All image processing by Noel Carboni, FLorida U.S.A.

Another beautiful image Greg - thanks for sharing!

PS - I thought M33 was quite bright - why do you need almost 14 hours worth of exposure?

Wow! You gotta love those stars! And I thought it was boring to wait for 30 seconds at max shutter speed duration (on my d80 that is) :D

Looks like a professional image, great work. You captured some great colors and the level of detail is incredible.

Thank you very much everyone :D
M33 at first sight looks bright, it even looks reasonable on the monitor - but in fact it has an extremely low surface brightness. If you look at the outer regions of the galaxy they are very faint even with such a long exposure time. The galaxy itself may even look (at first sight) noisy, but this is in fact unresolved stars.

Interesting, well the outcome looks great. Do you have any ideas on what your next project will be?

Yes - my whiteboard is covered in targets for this month :D
I want to get deeper data on the IC59/63 nebulae that I took about a week ago (Gamma Cassiopeia), and I am obsessed with capturing CTB1 - a supernova remnant in Cepheus, which is extremely faint as well.
