Acquisition type: Lucky imaging

Testing a small Coronado PST (personal solar telescope) was a lot of fun. As you can see, it can produce nice photographs.

I've calibrated the frames using bias/darkflat/flats to give a good even impression of the image. I attach the flat as revision B for any1 that is interested. To make the flat I've used an LED panel, and it is untrue they don't work... I just needed moderate gain and 15 s per flat frame (in this case the dark flats were very important).

Interesting stuff and much fun for me!

Description: Taking pictures with the Coronado PST is IMO less fun than viewing using the eyepiece. The scope is so light, it can be mounted on a classic photographic tripod!

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.
