Witch Head Nebula

Taken last winter, I forgot to post this image. Looking back, we had a nice weather spell in February.

When I first took it I was fighting the issues I discovered with Nikons using low ISO and fast lenses (f/2 - 200 ISO) and had a tough time correcting it and somehow forgot to post it.

I really like this lens now and now that I've found you can solve the issues by using a higher ISO so I am happy I kept it. Sort of a reverse of what I was doing. The issue was extreme rings that cannot be easily calibrated/corrected. For this image I used different ISO flats to solve it but it did some damage that I was able to somehow correct. Shooting at F/2 is very sensitive to calibrations.

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.
