M83 - zwo asi2600mc / mn190

[Retrograde]

Hi all,
another image from my week away to dark skies last month.
This was really my first light with the ZWO ASI2600MC as M83 came up earlier than the other objects I was imaging but has taken a while for me to process it to the point where I'm reasonably happy with it.

I'm sure this is news to almost no-one here but galaxy imaging sure is hard! :lol:

This is roughly 2.5 hours worth of OSC through the MN190. I captured a small amount of Ha as well but when I tried to combine it I couldn't even notice any difference so ended up leaving it out. The data is probably a tad soft as I was still trying to get everything working properly and I already ditched quite a few subs before stacking, but anyway here it is.

C & CC Welcome as always.

Hi Pete. If that’s your first light from this combo then wow we are all in for a treat to follow you along on your journey. This is a belter!! Great work

A lot depends on seeing too, some nights are good, and some are just very average. Also I find with my refractor, the image shift in the first 2 hours of cooling down causes issues. It’s on of those things, that to get a perfect image lots of things have to go perfectly….. never happens in my experience.
I think the chip that runs these cameras will become a pivotal point in cmos imaging as they are just so clean, and go quite deep quite quickly.
Your image is fine, it’s smooth enough that you can run a bit of deconvoltion to bring out a bit more detail, I also did this target and like you tried the Ha…. It didn’t make much difference to me either really.

Thanks Adam - much appreciated.



Cheers Clive - seeing was definitely less than ideal during the imaging run.
I did try a small amount of sharpening on the galaxy but it didn't improve the image. As far as the Ha goes I think a better image scale would help there (& possibly longer Ha integration - I only had about 40 mins worth).

Imaging with the DSLR on the MN190 didn't show up temperature related focus shift as much, I guess due to bigger pixels & less overall resolution. I'll just have to get into the habit of checking focus more regularly & perhaps investing in a Bahtinov mask to suit. :thumbsup:

Nice shot Pete :thumbsup:

Look forward to you getting the hang of the new optical train, looks promising!
