| Description | This is a classic peculiar galaxy where the interaction between NGC 2445 and 2444, after modern observations, is thought to have stimulated intense star formation along the bridge between them. Most of the bright spots on 2445 (dark in the inverted images) are thought to be new star formation structures as well. From the category, Arp seemed to thing that NGC 2445 "emanated" from the Elliptical galaxy NGC 2444. His remarks, "Diffuse counter filament" is a bit challenging to interpret, though I take it to mean the gray "haze" that shows up in his image, and the "dust" that seems to surround both galaxies in my wider field image. Captured on a crummy January evening with a layer of high clouds, mediocre seeing, and cut short by low clouds. I was hoping to observe for at least 2x the time I managed. |
