IC 1396A - Elephants Trunk or The Call of Cthulhu

Hello,
Here I show you IC 1396A - Elephant's Trunk Nebula. Or the Call of Cthulhu (H. P. Lovecraft) ;)
The picture is far from perfect. I still have problems with the optics here but wanted to show it anyway. That's why I didn't put too much effort into editing. Lights from two sessions were included.

On the one hand, I have double spikes on the stars in one direction and I still have no idea where that comes from. I have already checked the main mirror cell to ensure that the screws are not too tight. I recently installed a self-made aperture ring here.

In addition, my astro-modified EOS RP was used here for the first time, with the new OffAxisGuider. The distance to the GPU coma corrector is not yet correct. I've already shortened the spacer rings a bit and it's getting better. The next test is still pending.

The telescope and coma correction used are not really intended to be operated with a full-format chip.

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.
