Galaxies from last night

[callump]

Last night (2020-09-20) was not the clearest of skies, but I managed to capture a few galaxies.

NGC 404 - AKA Mirach's Ghost - was actually easier than I had expected...

NGC 891 - the Silver Sliver galaxy

NGC 507 and NGC 507 Group of Galaxies V V 209

With the astrometry.net annotated view.

Finally an oddity, marked on the Interstellarum Deep Sky Atlas - Barbon's Galaxy. Discovered by Roberto Barbon in the late 1960's i think.

It was highlighted to him as a faint smudge on a plate - Barbon took a spectrum to reveal it as a galaxy. It is a Blue Compact Galaxy - if the conditions had been better I might have tried an LRGB to see if it had a blue excess.

Very nice shots. NGC 891 is wonderful.

I've never heard of Barbon's galaxy -- thanks for that. Sounds like a task for LRGB indeed.

By coincidence some of the recent things I've been looking at included Mirach's Ghost and the the Silver Sliver.

I was prompted to look at Mirach's Ghost by McCavity's post on the EEVA Discussion forum.

 

Here's what I saw. It should appeal to those who like a diffraction spike:

 

The Silver Sliver Galaxy came up when I was having a short session looking at things in Triangulum. I decided to have a look at things other than M33 for a change and drifted over into Andromeda to look at things other than M31.

 

Cheers

Hi all,

Mirach's Ghost, 891, 507 group are all visual favourites of mine. Barbon's galaxy - new to me.

Bill - those diffraction spikes do it for me!!!

I like a diffraction spike when it is a real diffraction spike (like here!)

I too like diffraction spikes, but not when something is twisted, generating secondary spikes (if you excuse the pun). What is it that causes them? (I will try to fix now that the weather has closed in again..)

I too was inspired by Macavity's post a couple of weeks back:
