M64 Black Eye Galaxy

This is my third color target. The reason why I chose M64 those nights is this:
I use an Alt-Az mount and a mono camera with filter wheel.

Complications:
The steepest angle I can shoot upwards is 70 degrees, then the camera collides with the fork mount.
Field rotation is a huge deal. Not only can it drastically reduce the exposure time, it also can lead to a much smaller framing after stacking all differently oriented filtered images.

The goal:
Shooting 30s exposures and keep as much of the camera framing as possible.

My solution:
There are certain directions and times where there is fairly little to almost no field rotation in your relative view. This is usually almost precisely facing west or east.
Any target in that direction between 40-70degrees up gives me a window of about 2h for shooting as many 30s subs as possible
On the 11th and 13th of March (2023) M64 fell into this window.

After deleting bad images I ended up with
Red x 24 (30)
Green x 21 (30)
Blue x 36 (16+30 day2)
Luminance x 24 (30)
H alpha x 27 (30 day2)

However I ended up processing only R/G/B.

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.
