NGC 4449 is a dwarf irregular galaxy of some 19,000 light-years across, located about 12.5 million light-years away in the constellation Canes Venatici. It is part of the M94 Group (the Canes Venatici I Group), a galaxy group relatively close to the Local Group (which contains our Milky Way galaxy). It is moving away from us at about 207 kilometers per second.NGC 4449 is similar in size, shape and brightness, and often compared to, the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Unlike the Large Magellanic Cloud, however, NGC 4449 is considered a starburst galaxy due to its high rate of star formation.

R - 50 x 120s
G - 50 x 120s
B - 50 x 120s
Ha - 118 x 300s
Planned to capture more than 3 hours of Luminance data. But due to moon phases I ended up capturing more Ha data than Luminance.
Imaging from North East America has been a real challenge. With limited clear skies, Canadian forest fires and jet streams, I decided to end the acquisition efforts for this target and focus on other targets. May be I'll add more quality data in the next year.
