Comet C/2020 F8 SWAN at 666mm

This is my final C/2020 Swan attempt.

Despite getting up at 3am yet again and leaving my mount setup outside and telescope & camera ready and waiting in the garage, I had mount slewing problems that ended up being caused by a corrupt Logitech hand controller configuration. Anyway I managed to get 25 minutes imaging in of the 60 I was hoping for.

I obtained 50 x 30 second images, 6 x 10 second and 6 x 5 second at ISO 3200. I blended the resulting stack in photoshop to expand the dynamic range of the comet's coma and nucleus.

This is with a Saxon 127mm triplet refractor with 0.7x reducer (666mm FL) and a Central DS Canon 6D running at -4 degrees Celsius.

I managed to track on the comet's head in PHD for most of the session and then got a few images tracking the stars and blended the two image sets in Photoshop.

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.
