Acquisition type: Lucky imaging

almost 18 hours of unguided exposures taken on the nights of the 9th, 10th and 11th of April. Telescope was a TS65Flat with an unmodded Nikon d5300 on top of an Ioptron CEM60. This image will be used to apply color to the other mono images of the galaxies taken on the same day (setup was Ioptron CEM60EC + QHY183 + Newton Orion 250 f 3.9 as main imaging train. On top of the Newton is mounted the TS65 with the unmodded Nikon d5300.

Stacking with DSS and processing (as processing only crop and a few adjustment on color - nothing else has been done on the image) done with Astroart.

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.
