Eulenhaufen NGC 457 in der Kassiopeia

Diese Aufnahme des Eulenhaufens NGC 457 ist gleichsam als historisch zu bezeichnen und ist noch aus der Zeit, als ich mit der digitalen DSLR gerade anfing zu arbeiten. Bis dahin war ich noch analog mit Diafilm (Kodak Ektachrome 200) unterwegs und verfügte auch noch nicht über den (genialen !) Autoguider MGEN. Das war jedes Mal eine Heidenarbeit, mit dem Auge ständig das Fadenkreuz samt Leitstern überwachen und jede kleine erkennbare Abweichung sofort via Handtaster korrigieren. Zumeist hatte man dabei noch eine unbequeme Körperhaltung, so dass das Leitrohr dann oft zum "Leidrohr" wurde. Von Subpixelgenauigkeit beim Nachführen konnte auch keine Rede sein. Also brauchte man noch ein relativ langbrennweitiges Nachführinstrument. Ich nutzte zu diesem Zweck entsprechend einen kleinen Refraktor 60/700 mm von Tasco. Ach wie schön, dass man diese anstrengende Nachführtätigkeit heutzutage einem Autoguider überlassen kann. Von Darks und Flats hatte ich damals auch noch keine Ahnung. Aber seht selbst...

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.
