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 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.
The distance to this Glaxy M63, based upon the luminosity-distance measurement is 29,300,000 light-years, meaning that the light of the stars on this galaxy needs more than 29 million years to arrive to my camera…..
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 0.41×0.29 arcmin of size.
