M83 Southern Pinwheel Galaxy

Images from the following three scope/camera combinations contributed to this image:

AG12+ASI1600MM at .70 asec/pix

TV127is+ASI183MM at .75 asec/pix.

TV127is+ASI1600MM at 1.18 asec/pix

They were all registered to the best R image taken on the AG12+ASI1600MM.

L was created synthetically from the integrated RGB images.

I find this galaxy rather challenging to image. It never gets above 24 degrees at my latitude, so the seeing is never really good. Imaged on nights of 5/17, 5/18, 6/18, 6/19/2018, 3/16/2019, 4/15/2019 . Besides being at a low altitude, I was plagued by bad seeing and intermittent clouds. I ended up throwing away about 2/3 rds of the subs I took.

Messier 83 (also known as the Southern Pinwheel Galaxy, M83 or NGC 5236) is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars. Six supernovae (SN 1923A, SN 1945B, SN 1950B, SN 1957D, SN 1968L and SN 1983N) have been observed in M83. Its nickname of the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
