A bit of fun with A S&T

The current edition of AS&T at p.74 carries an image of a very faint fuzzy - ESO146-5 which it describes as the most distant 'normal' galaxy visible in amateur class instruments and the accompanying article talks about it being visible at high power in a 46cm scope as a tiny, faint spot.

I don't mind a challenge - and I expect others in IIS will want to have a crack at this also.

Here's my cut on it. I cropped it to more or less match the AS&T article's image.

The data says the central feature is an elliptical (AGC 3827) in the process of swallowing several others 1.37 Billion LY away in Indus and measuring a whopping 0.8'x0.5'.

[EdgeHD14" at F11 with ATIK11002M unfiltered and Binned x 2. 3 x 30 minutes - would have been more but I turned on the hair dryer and blew the fuses.


Enjoy.

Peter.
