Southern Pinwheel and the Hamburger

[MarsG76]

Hello again,

Similarly to my past post, after a long stretch of rain, I had a break with two clear nights., which resulted in two more images to share.

Not wanting to waste this, ever increasingly rare, night sky clarity, I opened the observatory and exposed luma subs during the first night and the second night was spent capturing RGB subs... first half of the night was spent on the Hamburger Galaxy, NGC 3628, and the second half after midnight was spent on M83.

The Hamburger is relatively low in the northern sky from my location, which was possibly effected by thermal currents radiating from the house roofs directly below the galaxy position. Alternately the Southern Pinwheel exposure started when it was directly overhead and was high in the sky for the duration of the exposure.

These images were exposed across two nights, 3-4 & 4-5 April 2022, using a QHY268M through a Celestron C8" SCT at the native 2032mm focal length, tracked on a Hypertuned CGEM mount.

Total exposure time of the Hamburger was 6 hours and 23 minutes, and M83 was 5 hours and 47 minutes through all LRGB filters.
The thing I hate most about this cloud dodging imaging is that it seems rushed, with the uncertainty if there will be enough clear sky to finish images.

CS,

Mariusz
