IC1396 (Elephant's Trunk Nebula)

This is my very first nebula in narrow band. It was a bit of a challenge to acquire since I only had an windows of about an hour each night, in between it emerging from behind the street lamp and dawn, so I had to get this little data over two nights. It certainly needs more integration. Just a quick processing, nothing fancy.

7 x 10m Ha, 4 x 10m OIII/S2 each, unity gain (139/offset 21)

2x 20 flats each night, 40 darks & 40 dark flats.

Lacerta Newton 250 f4/1000mm , ZWO ASI1600mm at -15deg, Astronomik Ha/OIII/SII 6nm 36mm filters, iOptron CEM70. Guided OAG/ASI290m. Stacked with DSS and processed with PixInsight.

Backyard, Naas town/Bortle 5.

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.
