Hanny's Voorwerp in Leo Minor



Hanny's Voorwerp with an ASA N8 20cm f2.75 astrograph and modified Canon 350D

On the left of this comparison an image made by Bill Keel with the 90cm SARA telescope, on the right my 36 - 5 minute exposures on December 25, 2008, SQM reading 20.4 mag/square arcsec.
My image was resized (150%) and the SARA image was reduced in size to compare them more easily. This image was made with a modified Canon 40D, and a 20cm (8") f/2.75 ASA Astrograph.
