Arp 245 in Hydra

The February 2020 galaxy of the month is one of the most intriguing pairs in the Herschel catalog, although when I observed these two with my old 12-inch three years ago I could not see any details.

I am attaching a new sketch that I made with my 20-inch, observing from our dark site in the Appalachian region of Pennsylvania (SQM 21.5, seeing 2").

A sketch on black paper finished at the telescope of Arp 245 by Ivan Maly.

The sketch was made at 250x, and I also examined the field at higher and lower magnifications. The arm in NGC 2993, the connecting material, and the RFGC remained invisible. I blame reflection from fresh snow, which was noticeably brightening the sky even though we had excellent transparency.

The sketch on black paper was finished at the telescope.

Ivan Maly - (15 February 2020).
