Arp210
Galaxy in Camelopardalis
About
Camelopardalis holds NGC 1569, an irregular dwarf galaxy about 11 million light-years away that belongs to the IC 342 group. Arp listed it among galaxies with irregularities, absorption and resolution. Across 100 million years it has formed stars roughly 100 times faster than the Milky Way does, and its core holds three giant star clusters.
Imaging tips
- Only about 3′ × 2′, so it is too small to frame: use a long focal length and a fine pixel scale.
- At 21.7 mag/arcsec² it is not among the faintest galaxies, though it sits behind dust of the Milky Way.
- One imager shot LRGB with a 500 mm f/7.2 Cassegrain, listing 310, 70, 70 and 70 minutes across the four filters.
- Another imager added about an hour of Hα, hoping for two, after Hubble featured the galaxy in a press release.
- Best around November and December, when it reaches about 75° from 50°N.
