Lbn552 and Ldn1228 - The Dragons of Cepheus Two Panel Mosaic

This is a complex of mostly dark nebulae located near the North celestial pole in the constellation Cepheus. There are also a few reflection nebula visible in the image including RNO129 and NGC2261. Within these are a number of Herbig-Haro objects showing off their characteristic orange glow.

This was my first ever unguided image! All frames were captured with guiding turned off. I have finally been able to fine tune my GM2000 rig to track as good or better than when I am using the OAG. That means one less piece of software and hardware to manage and less time used for guider settling and calibration.

This is a two panel mosaic stitched together using the Photometric Mosaic script in PixInsight. Mosaics are always a challenge, and this one proved to be no different. I probably have more processing time invested in this image than my last three combined. There are just so many variables to deal with and workflow options to consider. Dark nebula on their own are challenging to process let alone in a mosaic!

Hope you like the result.

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.
