My first attempt at Comet C/2022 E3 (ZTF) from my back garden - I've been waiting for it to rise high enough and early enough (just after midnight). It's also my first Comet, apart from Neowise which I only shot with a DSLR on a standard tripod.

I decided to go with 60s exposures for each filter and only took 20 mins each of R,G and B due to the speed it's moving. Processing was a challenge and there are still a few artifacts which need sorting out but overall I'm pleased.

I was also lucky to catch the Splinter Galaxy (NGC 5906) in the frame.

Title: Reprocess

Description: A complete reprocess as the original version had alignment issues resulting in a blurred core. I recalibrated all subs then used Pixinsight-->StarXTerminator Batch mode to remove the stars. I then used CometRegistration, also in Pixinsight, before returning to APP for final integration and Photoshop for adding the stars back.

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.
