Astro-Tech AT115EDT first light test - Messier 33 Triangulum Galaxy

Revision title: Final cleanup in photoshop

First light on a new Astro-Tech AT115EDT: a 115mm f/7 APO triplet. I'm using their 0.8x flattener, along with a zwo OAG and filter drawer, and a paper spacer to help with camera rotation relative to the OAG prism.

This test is a quick 12 x 300 sec on Messier 33, mounted on an overworked cem26. I only hand-focused with a Bahtinov mask, and I accidentally used a gain of 50, so this should improve further.

(a) barely processed image stack
(b) ASTAP tilt analysis (using "more stars")
(c) ASTAP aberation inspector
(d) cleaned up image

I'm pretty thrilled! I've never had a scope work this well out of the gate. The mechanics are solid, too.

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.
