This time it didn't go as smoothly. I got the coordinates for the center of the picture from Blackwater Skies again. It should be reproducible. Probably had a little underpriced. IC 1396 hadn't got as far to the left as planned. I thought so be it and I started the exposures. Unfortunately 3 minutes were too long. Then set to 2 minutes and turned the ISO up a bit, the stars were now round. The 80D had tolerated the higher ISO number well.

- no guiding

- no darks

------------------------------

Dieses mal lief es nicht ganz so reibungslos. Ich hatte mir wieder die Koordinaten für die Bildmitte aus Blackwater Skies geholt. Es sollte ja reproduzierbar sein. Hatte wahrscheinlich etwas zu knapp kalkuliert. IC 1396 war nicht so weit nach links gekommen, wie geplant. Ich dachte, so sei es dann und ich fing mit den Belichtungen an. 3 Minuten waren leider zu lang. Hatte dann auf 2 Minuten gestellt und die ISO etwas hochgedreht, die Sterne waren jetzt rund. Die 80D hatte die höhere ISO-Zahl gut vertragen.

- kein Guiding

- keine Darks

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.
