M51 - Getting started with Autoguiding

I am trying to get Autoguiding working. The mount is an Bresser Exos-2, autoguided with PHD2. I have a finder scope with an ASI 120 CCD for guiding purposes. The mount is connected to my laptop with an RS232 cable via the handbox. This is more complicated than I thought. Spent 3 nights until I started to get use-able guiding results. The single frames look okay, almost no star trailing. Still have to fine tune the PHD settings. I do something wrong with the post-processing to get that weird looking stars. The image is around 50% cropped.

These are 12x 2.5 minute frames, shot in holidays in Haute-Provence. Amazing sky here ... Looking forward to do some longer integrations while I am here.

Version C: Went back to this image to reprocess. This time with 2x drizzle and more natural colors. I think there is a bit better contrast and more details now. This picture is the result of my first auto-guiding attempt so it is a bit special to me. The sky was amazingly dark during these holidays, I will never get this kind of image with only 30 minutes exposure in my backyard...

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.
