WBL 727 (NGC 7778 etc) Also NGC 750 and 751

[Bill S]

Managed to get a bit of viewing done early this morning. My first opportunity for several weeks.

I always have a look at what is suggested as the Webb Deep Sky Society Galaxy of the Month. October 2019 is NGC 7778 in Pisces.

There is lot of explanation in Owen Brazell's article which I won't repeat. But in the field we are able to see the WBL 727 group. (Martin Meredith has mentioned WBL groups previously, most recently in a posts earlier this month.

This is one of my snapshots of WBL 727 (NGC 7778, 7782 etc) using my Lodestar X2 with a focal reducer on my 200 mm Newtonian collected with Starlight Live and viewed in real time using Jocular. I've put the picture through All Sky Plate Solver to mark up some of the galaxies.

I didn't need a long stacked exposure to see everything. I left it running while I was reading up about what I was looking at. 

I did wonder if I could pick out the very faint RFGC 4209 Owen Brazell mentions but I've come to the conclusion it was outside the area of the snapshot.

 

The Webb Society article refers to this:

http://images.mantrapskies.com/catalog/NGC/NGC7778-NGC7779-NGC7780-NGC7781-NGC7782-WBL727/index.htm

In these articles we find that RFGC 4209 (RFGC = Revised Flat Galaxy Catalogue) is also known as LEDA 091829 and FGC 2548

Something to look for another night, perhaps.

I also had a look at the Galaxy of the Month for September 2019 because I had not had a chance earlier. This is/was NGC 750 in Triangulum.

This article points out that the pair NGC 750 and 751 forms Arp 166. Again here's a snapshot that's been plate solved to label some of the galaxies, especially the Arp 166 members..

 

Once again the long exposure was not really necessary but I continued collecting subs while I was looking at background information.

By then it was time for bed.

Clear skies!

Hi Bill, I agree that it has not been a particular good run of weather. Here is my shot of NGC 750 with other galaxies circled. Mike

Nice work Bill! This must be the first time anyone has put a Jocular image into the plate-solver. Automating this is an idea for a future integration.....

I was out looking at WBLs in Pisces on Friday but high thin invisible cloud made them noisier than I would have liked.
