The IC1396 emission nebula in Cepheus, home to the famous Elephant’s Trunk Nebula. It is a large emissions nebula with stunning inlays of dust clouds absorbing most of the lights. The total size of the IC1396 complex corresponds to about 10 times the full moon.

This is a straight Ha monochrome image constructed from 15 exposures with 600 sec each, a total of 2.5 hours of exposure. Using my wide-field setup with the Asahi/Pentax Takumar 135mm f/2.5 with the ATIK 460EXm. Taken from the balcony of my house in the light-polluted Frankfurt area – Bortle class 7 (red zone). This is the “first-light” for my self-constructed wooden pier, which worked like a charm. Guiding rms-errors of the AZ-EQ6 during the 10 min exposures were on the order of 0.4 arcsec.

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.
