Revision title: Deconvolved with star reduction

Against all odds, the first night after the arrival of my new camera and scope was not only a clear one, but also coinciding with a New Moon and also particularly transparent since this was the first sunny day after four days of rain.
The new equipment worked up to expectations and even better, the only thing that surprised me was the field curvature showing up already on the 183MM sensor.
Given my past experience with a refractor of similar focal length (the Stratravel 80) I thought it would have been visible only on the corners of my DSLR APS-C sensor.
Presently I have no flattener fitting a DSLR, but I should be able to use the Starizona one I just bought for the Evoguide 50 also on this scope, albeit only for the ZWO cameras.
Not that I really love all the pantomime coming with precise spacing when you have to deal with flatteners ...

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.
