Object name: NGC0450
Designation(s): NGC0450, NGC0442,
NGC 450, located in Cetus, and it's "companion" UGC 807 would seem to qualify for Arp's Atlas of Peculiar Galaxies on two accounts. First NGC 450 is a low surface brightness galaxy which was Arp's first category. Secondly, it would also qualify as a spiral with a high surface brightness companion on its arm. Guess he figured he had enough of both. In many cases of his category for spirals with companions on the arms, there were no redshift values either at the time of his atlas or today to decide if they were real companions or just line of sight galaxies. In many cases, the small galaxy seemed undimmed by the dust and gas of the spiral. I'd mention I didn't think they were related with the small one likely far beyond the bigger spiral. I'd get challenged on that from time to time. I'd point out that its quite possible for a spiral to have used up most of its dust and gas except in obvious dust lanes so the lack of dimming didn't necessarily mean the companion wasn't a distant galaxy.
