M101 - Epsilon 160ED first light

Revision title: M101 with Supernova SN2023IXF

First light with this new Epsilon 160ED. I paired it with Player One's new Poseidon camera and Astronomic Deep Sky RGB and MaxFR filters.

The Player One OAG hits the focuser housing on the Epsilon, so I had to use a guide scope instead. In talking to Sean at Player One they have already started manufacturing an updated housing for the OAG that will not do this, and they'll be sending that over once it's done being made (in the next month).

I wasn't sure how well the Epsilon would work in my bortle 9 skies, but one night on this target turned out really well. Compared to the recent TOA-130 image I took it's a lot brighter given a similar amount of integration time. We had poor seeing last night, but HFR measurements showed the average frame was around 1.70 with frames towards the morning reaching 2.2 as humidity increased.Hocus focus was fairly easy to dial in, but didn't like measurement sizes larger than about 20 steps per measurement.

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.
