This was my second time imaging with the Canon 10D digital SLR camera attached to a 20 inch Starmaster using a Denkmeier prototype 2 inch OCS. The Denkmeier OCS allows prime focus imaging at a magnification of about 1.3X without shortening of the scope's truss poles. The final version of the OCS should provide less vignetting but I have not received it yet for testing.
Ambient temperatures were in the high 30 degrees Fahrenheit. Winds were variable and did not allow very long exposures with the 20" dob, which presents a quite large surface area to the wind. I imaged objects such as the Moon, Jupiter and star clusters that required shorter exposure lengths. A Televue two inch 2X Barlow was used in conjunction with the two inch Denkmeier OCS for Lunar and Jupiter images.
NEAT IMAGE was used for noise reduction.
