Cartwheel galaxy with OSC camera from bright sky - EdgeHD11 ASI183mc f/7

This is the famous Cartwheel galaxy in Sculptor - imaged from fairly bright suburban Melbourne skies with SQM 18.6 mag/arcsec^2 with an OSC camera, ASI183MC. EdgeHD11 f/7. 64x5m exposures over a few nights.

This is a very interesting galaxy structure that isn't imaged very much, but can be captured with a backyard setup and OSC camera with no special filters. Details in the galaxies are visible - along with several faint background galaxies.

Raw pixel scale is 0.25" per pixel, resampled x2 to 0.5" per pixel for the final version. Bayer drizzled with custom code using nearest neighbor interpolation and gradient removal - then linear scaled and imported to Photoshop for application of levels to stretch. Finally a x2 reduction in size to 0.5" per pixel. No denoising or other color alteration.

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.
