Description

Probably the last picture with this setup, the last one with the ASI1600M / ASI183M.
I am upgrading my set up to QHY268M / QHY294M and also from the Riccardi reducer to  TS-Optics RC 0.8x. (more info here)
It's a long process, to many changes.

But here is my Sunflower version.
It's an integration time of a little more than 24 hours.

From that version in 2017  https://astrob.in/292513/D/ to the current one, a lot of things happen.

It's a difficult object to me despite that I saw a good evolution over the years.
Always was like a defocus image, on this last picture I do all my best to correct that.  
This is my last try with that focal 
Now I changed my cameras but I am not sure if this change could produce better results. Maybe will check next year.

It's interesting how many other galaxies appear on the field.
Only with the PGC Catalog you could see another 7 but including the SDSS catalog up to mag. 19..... another 216 galaxies are annotated (it's full of galaxies, not stars!!)

I am proud to show the PGC46093 (in green) with a mean surface brightness of 24.4 Mag/arc-sec²



My favorite is the spiral galaxy PGC2187167 (in red on the previous image), here is a crop of this object with 0.41x0.29 arcmin of size.
