Cepheus Mosaic - Nine Sharpless (Adrenaline)

Cepheus Mosaic - Nine Sharpless

I've decided to approach mosaics using a stealth regime - a pane at a time!

Last year I decided to try to complete a 40 panes monster-mosaic of Cepheus. I managed to get the Ha covered, although it proved difficult to stitch together. The weather conspired to ensure I never got any of the OIII or SII.

So this autumn I am having another go but adding a pane at a time and see how it develops - other than slowly!

The real object of the exercise is to image the nebulosity and identify the Sharpless objects, so here are nine Sh's in the first three panes - that has gone from one pane to two panes and now three. The overlap is considerable, almost 50%, so despite each pane only being 12 x 300s on each filter the central regions of each mosaic will be at least twice that amount.

Focussing on the nebulosity means (to me) leaving out the stars - courtesy of StarXterminator.

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.
