Messier 82 (NGC 3034)
Irregular Galaxy in Ursa Major RA 09h 55m 48s Dec +69d 41m 00s

The irregular galaxy M82 (NGC 3034) lies to the right of this image by Adrian Brown, which also shows
the spiral galaxy M81 (NGC 3031) to the left. M81's faint satellite galaxy Holmberg IX is visible above M81 itself. Adrian photographed these galaxies with his Skywatcher 80ED refractor and an ATK16HR
camera. The data was collected on the evenings of the 1st and 4th March 2006 and consists of 1.5 hours luminance (5 minute sub exposures)
and 30 minutes (3 minute sub exposures) each through RGB filters. The digital development process (DDP) filter in Maxim DL was used to bring
out detail in the galaxy cores and this detail was then sharpened via the application of a high-pass filter in Adobe Photoshop.

Chris Newsome and Adrian Brown captured the following image of M82 on the 19th February 2006. They used a Canon
EOS300D camera at 400 ASA through Adrian's Celestron C11 fitted with a f/6.3 focal reducer, mounted on a CGE mount and guided using Guidedog
software with focusing using DSLRFocus. An Astronomik CLS filter was also used to remove sodium light. Five images were
taken at 210 seconds exposure and calibrated in Maxim DL. The resulting image was then processed in CS2 using RGB levels, curves,
GradientXTerminator and a highpass filter.
