A two-panel mosaic of this rarely shot Nebula in Cepheus.
The star of the show is of course on the right, reminding me a bit of the Tulip in Cepheus.
NASA's Spitzer Space Telescope imaged the center of SH140 back in 2003 - There's a hidden cluster in there.

I usually dread mosaics since I don't have the best weather to pursue a multi-frame target.
But I wanted to test how it will work with my Newt.
There are unfortunately some stitching artifacts.
I had to shoot this over a long period of time and the camera came off a couple of times.
So framing wasn't very matched between sessions.
Not sure if a different software would do better than Pixinsight.

About 8 hours of Halpha per panel and 90 minutes for each RGB channel per panel.
All shot from the city of Kingston, Ontario - Bortle 7-8

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.
