Sh2-134, Sh2-135 - Ha Region in Cepheus

Sh2-134 / Sh2-135 - broad Ha emission region in constellation Cepheus.

First mosaic - have wanted to create a mosaic for a while and was curious to check out the PI mosaic creation scripts - so a proof of concept learning exercise.

NINA was used to plan and capture the panels. Would have used an OSC, but I only have mono cameras, so the simple case was a 4 panel mosaic in Ha only. This Ha region of Cepheus fortunately happened to be in season for my location. Processing was calibration as usual / mosaic creation / stretching and a bit of LHE to add some contrast to the grey.

Subs were taken over 5 nights between Sept 09 and Oct 08. Shot subs for each of the 4 panels each night, as opposed to spending a night per panel process. A lot more slewing and focusing but I hoped this would provide more compatible panels for the mosaic creation. One lesson learned was that any smoke and moon combination destroys transparency and sub quality.

Definitely pleased with the quality and ease of use of the tools - both NINA and PI.

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.
