| Description | This was a "2 for" - a second Arp galaxy group within the same FOV as "Minkowski's Object" (Arp 133). It consists of two interacting galaxies (L to R): NGC 545, a lenticular galaxy, and NGC 547, an elliptical galaxy. During capture I noticed an extended halo from NGC 545 up and to the right towards Arp 133 (southeast given that N is left in these images), which became more pronounced after processing. Arp, himself, doesn't mention it in comments, saying: "Close ellipticals. Position of central galaxy (NGC 541)". |
