NGC253 again.
It´s not so that I havn´t imaged that galaxy often enough but for experimenting it is a great target.
While I was waiting for my object of the night to come up I took 3 hours of luminance this time with 10min. subs.
I´m using high gain for everything so I thought it might really burn out but the subs were fine.
The limiting magnitude of the single subs is 22.4 so more that one magnitude higher than on the usual 3min and the stack clearly showed the halo around the galaxy.
I still have to compare a 3 hours stack of 3min. subs to the 10min. subs but it definitely seems to give deeper results.

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.
