Needle Galaxy (NGC4565): First light in a short night

I had almost given up on my chances of trying my new Esprit 150 before astrodarkness will be gone from up here, but last night gave me the opportunity. Very nice and clear and surpisingly dark for about three hours (SQM=21.0 at midnight). So here is two hours of first light with the Esprit (10 x 12 min at ISO1600). Guiding was bad (RSM around 1.5"), probably due poor polar alignment (the pillar has probably shifted a bit when the ground now has thowed out) and possibly some balancing issues since I put the Esprit next to my ES 5" refractor (which turned out to point at some random target...). I hope to collect another two hours tonight, but here is the real first light. The scope is fitted with the dedicated SW flattener.

In version C there is an additional 8 x 12 min added from last night (most likely the final night of the season)

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.
