Galaxy NGC 3184 rocketed to notoriety in 1999, when a Type II supernova (1999gi) was discovered on 12/9/99 by a Japanese amateur astronomer, taking
images similar to the one I obtained. The supernova shined bright enough to be seen through amateur telescopes for a few months, but has long since faded,
and cannot be seen in my image. At a distance of 25 million light years in the constellation Ursa Major, NGC 3184 is a classic spiral seen face on. Two bright
hydrogen II regions, appearing as red knots in the image, were originally described as different objects (NGC 3180 & 3181). NGC 3184 intrigues
professional astronomers with its abundant heavy elements.
This image combined 75 minutes of red, 75 minutes green and 100 minutes of blue exposures, binned 2x2 on a windy night. An ST10XME camera was used
through a Meade 12" LX200R and an AP reducer at my new observatory.
