NGC 884 (chi) und NGC 869 (h), Doppelsternhaufen im Perseus

Diese Aufnahme des vielleicht schönsten Sternhaufenpaares am Himmel ist, wie NGC 457, auch "historisch", weil mit gleichem Equipment entstanden. Da war Astrofotografie noch richtig harte Arbeit. Heutzutage wird kurz mal die GoTo-Taste gedrückt, das Bildfeld in der Kamera

eingerichtet, die Belichtungsreihe programmiert und dann der Autoguider kalibriert, Aufnahmeserie starten und es läuft alles wie von selbst. Danach kann man in´ s warme Wohnzimmer sich entspannen oder sogar schlafen gehen... Früher absolut undenkbar. Da fielen so manches mal beim Nachführen fast die Augen zu.

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.
