Abell 2666 and 2593 in Pegasus

[Martin Meredith]

After a 3+ months break, I managed decent session last night, looking at a variety of objects, mainly in the cluster-rich regions of Sagittarius, but straying into Pegasus later. As I finished the Pleiades were already quite high. Surprising how quickly summer turns to winter... 

Here are a couple of Abell galaxy clusters. No darks nor flats, just hot pixel removal. North is up. Other details on images.

Abell 2593 

This cluster is relatively close at around 600 M Lys. The brightest galaxy is NGC 7649, a mag 15.4 elliptical. This cluster benefits from an extensive set of magnitude data down to mag 22 so is useful in working out magnitude reach. The bright star at the base is mag 7.5 triple star Burnham 719.

 

 

Abell 2666

I'm including a screenshot with the details I wrote at the time. This is a really appealing cluster, containing a mix of different galaxy shapes, with a linear structure of variously-oriented edge-ons. Distance around 380 M Lyrs. The bright star near the centre is the variable GR Peg. This is 23 x 15s subs for a total of 5m 45s.

 

Thanks for looking

Martin

Nice report of some interesting galaxy clusters and nicely presented in Jocular.  Good to see you back in the saddle. 👍

A lovely area to explore and good to have your input back into the section. Mike
