M33 revisited

This image is almost ruined by the "diffraction spikes" from the ZS73II. I did take some measures to make them less asymmetric, but only after I had taken about 80% of the subs so I am not sure they made a difference. Probably not.

That said, the detail and dynamic range are quite good considering it was taken at a part of the sky that I normally stay well away from (the western lower horizon which almost a white zone) and that it was all short subs, unguided.

I did the usual Mono Lum + OSC RGC but Red and Blue were so far behind Green in the OSC image that I complemented them with a few hundred mono subs for each color.

I think I'll add another 1-2 thousands subs next year now that I got the hang of it. Unfortunately I must move on to other targets as M33 is now so low even the 5 second sub is blown out.

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.
