IC 1396 - open cluster with nebulosity

My first attempt at this open cluster and surrounding nebulosity. I was limited to a 2 hour window after sunset, before heavy mist settled in for the night. After the poor results I have been getting at 210mm with my zoom lens and L-eNhance filter, I tweaked the alignment of the optical train, and reduced the zoom to 150mm at f5.6 - a definite improvement.

The 2 hour image is made up of 15x300s L (L-eNhance filter), and 8x120s each RGB. Captured in Envisage, aligned in Nebulosity and processed in Startools. I tried to protect the stars using masks, and repair some elongation due to rotation, but the garnet star looks worse as a result.

IC 1396 is ionised by a bright star (at the bottom of the image) beside a dense globule IC 1396A - the elephant trunk nebula, (bottom centre in my image), a star factory. At 2,400 LY distant, I am pleased to have captured this detail in my fairly low resolution image.

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.
