IC1396 Elephant Trunk in SHO Aug 2023

A relatively short 4-hour integration of IC1396 in narrowband, but I still think it came out fairly appealing. In fact, despite being a SHO mapping, this may be one of my favorite busy star fields and might be even more interesting than the nebula. There are just so many!

Some tuneup on the HEQ5 Pro prior to the first sessions helped a lot also, providing some of my best guiding in a long time, often around 0.30, and really helped me retain the bulk of my 5 minute subs.

Stacked in WBPP, processed in StarTools 1.9 beta
SHO mapping of R: 50SII + 50Ha, G: 50Ha + 50OIII, B: 100OIII
Emissions balancing/throttling: 100% SII, 29% Ha, 57% OIII

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.
