Stephan's Quintett (GalacticRAVE)

Stephan's Quintett

To some object one has a strange emotional association. When I was at highschool I read an article in the astronomer's magazin (Sterne und Weltraum, the German analogue to sky and telescope) about someone hunting (visually) for Stephan's Quintett from a dark site in the Bavarian Alps (Sudelfeld). I was absolutely fascinated by this report and said to myself some day you do it yourself. ok, some 35-40 years later this my first attempt photographing SQ from my (not so dark) backyard.... This is probably the most difficult object I tried so far and certainly still plenty of room for fine tuning, but overall I like it, at least as a first try ...

Addendum after the first JWST data release: like many others I was quite excited (to say the least) to see the fantastic JWST data. And like others here, I was motivated to have again a look at my data of Stephan's Quintett and to reprocess it (after gaining almst 1 year of experience). Considering that the seeing in my backyard is not quite as good as at L2, and considering that I have not (yet) spent some 10 G$ on astro gear, I think this is not bad ...

Description: got a considerable number of additional subs, rebinned everything as it is oversampled anyway, and also major work on fine detail, in particular reducing chrominance noise in the less bright regions (between spiral arms etc). I also like the stars better now, but still room for improvement... At the end, differences are settled, but visible.

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.
