My first Andromeda ever! In addition, my first test with my Skywatcher Esprit 80 APO configuration including TeleVue TRF-2008 reducer/flattener, making this an extremely fast refractor (F4) with wide view so I could take this image in a single shot.

Unfortunately, my Mesu-Mount has problems (controller is broken) so I needed to use my Advanced VX, tracking was not that good but I could test my 80mm APO configuration anyways.

I found that my backfocus is not optimal yet. Therefore, I need to go ahead and do some testing to find the right backfocus for my configuration. It is not as per TeleVue description (56mm).

It is very hard to get a refractor this fast working correctly. Focus comes extremely critical and the working distances are very narrow.

It was almost full moon while taking this image (90%).

Considering this and all issues aside, I am quite happy with this result since it was the first time I used this setup.

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.
