NGC 2683 Ufo Galaxy

This is NGC 2683, the ufo-galaxy. The image is a bit blurred due to guiding problems which i am currently working on. This time i didn't use any bias frames (thanks to Zdenek Vojc via Michael Feigenbaum for this hint) and acquired totally new darks using the refrigerator-method (which is the best method to take darks i have used so far - totally stressless - thanks to Kevin Morefield for describing this in the forum). The resulting stacked image was a lot clearer and cleaner than the ones i stacked before. And i found flats from february which contained no annoying-noise-blob (see my previously uploaded images). The RC is very focus-stable so i could use these flats without any problems. Of course i check the focus each night, but mostly there is no need to touch the focuser :-) It means that the annoying-noise-blob-problem is still not solved, but for my latest images it should be fine.

I will reprocess my latest images with this new knowledge and new calibration frames and method. I hope there will be an visible improvement.

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.
