Hickson Compact Group 90

2020 has been kinda lean pickings and like many of you I'm sure, I have a pretty long list of potential targets for various times in the year. However, not living in 300 clear nights a year Chile and no fully automated remote rig, not to mention my scope is not even in my own backyard , so requires travel back and forth...inevitably time obviously gets away and so many candidates pass slowly by and get missed . Anyway, ever since I saw the HST version of this compact galaxy group, in Pisces went on my list

At around 100 million light yeras, the galaxies are not of large apparent size (around 1 or 2 arc min each). The main interacting trio, comprised of two elliptical galaxies, NGC7173/6 and a distorted spiral NGC7174, are joined by an intriguing looking edge on Seyfert2 galaxy, NGC 7172, which looks like a coffee bean (or cheeseburger). The whole group is connected by a subtle hub of faint galactic steams and along with the big bright mag6, F class star, HD20953, some intra cluster light also contributes to the glowing vista.
