Visually, the galaxy is quite large - about 70' x 40'. This makes the galaxy about 3 times larger than the full moon. However, unlike the Full Moon, M33 has a very low surface brightness, so it is quite challenging to see as well as to photograph: High Resolution Version and more image details available at http://www.astronomersdoitinthedark.com/index.php?c=113&p=475 This image was made from several stacks of data captured on 7 nights over the last 2 years. Last year, I gathered 231 x 3 minute subs (11 1/2 hours) of RGB @ ISO 1600 with a Canon 20Da using a Celestron orange tube C-8 with Celestron focal reducer at f/6.3 (1260mm). Guiding was with an 80mm Astro-Physics 80mm f/11 refractor, Orion SSAG, and Phd Guiding. With this year's data, I added 188 x 3 minutes of RGB (9 1/2 hours) at ISO 1600 plus 40 x 10 minutes of Ha (6 2/3 hours) using a 6nm clip filter captured to a Gary Honis modified (Baader mod) Canon 450D. Imaging scope was the same orange tube Celestron C-8 with Celestron focal reducer at f/5.8 (1160mm). Guiding this year was via an ONAG On-Axis Guider, Lodestar autoguider, and Phd Guiding. This year's RGB data was focused for the outer edges of the galaxy as well as the center of the galaxy, and I used focus stacking to combine these sets of data for sharper focus across the FOV. Ha data was used to highlight the Ha regions within the galaxy. As always, thank you for looking!

The most I've tried to combine is around 6 hours. Now that I've started guiding, I need to dust off my C8 after seeing results like this.
