NGC 7331 et al

This image was aquired together with Julian Zoller and Miriam Varding at the Landessternwarte Heidelberg, where I was employed as a B.Sc. student at the time of observation as a freetime project. Aquisition type "traveller" might be the most accurate, since we aquired the data ourselves but at a telescope belonging to an institution we needed to travel to without a scientific purpose.

NGC 7331 is a large spiral galaxy in the constellation Pegasus at a distance of roughly 46 million lightyears. In the background are many small galaxies further away and not gravitationally bound to NGC 7331, called the "Deer Lick Group".

More information about the Exposures:

Clear (no Filter): 90*90 sec bin2

Johnson R: 45*90 sec bin3

Johnson B: 45*90 sec bin3

G synthetic channel (V Filter was broken) 50% R + 50% B

no guiding used, custom observatory mount. Binning was necessairy because of the small pixel scale of ~0.33 "/pix in central european seeing conditions.

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.
