I really should not do this.
Well, I did it again, don't know why...
Maybe I needed this challenge.

And I have learned some things:

I learned about the right parameters to get the best guiding from my AM5 mount, and at nearly 2m FL this is absolutely essential.
I learned how to deal with N.I.N.A.

Does not sound like a lot? I think these are huge steps forward.
And yes, I made a picture, too ;-). Not a great one, but the reducer I was using only gave me 0.72x reduction in this imagetrain, so I landed at f11 and 1980mm FL.
There were nights that only gave me 15 minutes useable time for imaging, these were the nights I messed around with N.I.N.A. and configurations.

NGC 2586 (Arp 336), also known as the Helix Galaxy is a lenticular and polar ring Seyfert Type 2 galaxy in the constellation Ursa Major. It is about 50,000 light-years across and about 42 million light-years away from Earth. It is receding from Earth at 883 kilometers per second. It is an object of great scientific interest, because polar-ring galaxies are very rare galaxies. They are thought to form when two galaxies gravitationally interact with each other.

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.
