First Light Samyang 135mm f/2

During basically impossible conditions (moonlight was straight going into my new lens) I acquired 20 minutes of the Rosette Nebula. Well, some processing tricks, and this beauty popped up! I did not know that there are so many other objects around!

Shot at f/2 !!

Version A: Stack of TIFs without darks/flats/bias. Does anyone know what's the faint nebula on the lower left of the rosette?

Version B: Stack of RAW frames with darks/flats/bias. Cropped slightly to focus on Rosette and Christmas Tree.

Version C: I found out that I flattened out many details in Fitswork while I tried to remove the moon light pollution. New processing from scratch, new DSS settings, using superpixels. I know, it is a drastic processing, but many new structures appeared, including the dark nebula in the upper left and the two Sharpless nebulae in the lower left.

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.
