comet 62P/Tsuchinshan on 1st February 2024

Comet 62P/Tsuchinshan yesterday morning (February 1, 2024 between 04:45 and 06:45). It just fit into my frame along with galaxy M58 (far left) and a pair of interacting galaxies NGC 4567 and NGC 4568 (sometimes called the "Butterfly Galaxy" or "Siamese Twins").

The image was taken with a 2600MC (gain 0, T -10° C) Pro camera on an 11" EDGE HD Celestron with Hyperstar reducer (540mm focal length, f/1.9), EQ6R mount, pointing, controlled by ASIAir Plus. Composed of 90 images at 60s - calibration, composited to stars and comet in Siril, blended and fine-tuned in Photoshop.

I made a bold bet on the weather forecast, with rain all evening and winds of 40 km/h with gusts to 60 km/h - and that was still the situation at 2am when I went out into the field - but then the front passed, the winds calmed down and there was a beautiful sky from about 3am to 7am.

I originally wanted to shoot 3-4 hours to get the galaxies better (less noise, more detail). But I made a mistake in my preparation, I had outdated ephemeris in Stellarium, and I spent an awfully long time looking for the comet and tweaking the intended composition, so I lost a lot of precious time. In the meantime, interrupting the shoot for a meridian flip and other complications. I need to be better prepared next time!

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.
