Rosette Nebula (Caldwell 49)

This is my first image with my new imaging setup. There is still a lot to tune. I haven't dialled in the backfocus distance behind the reducer yet, there is a lot of star flaring near the edges of the field (cropped). Also I believe guiding can be much improved. However before the lengthy process of fine tuning the equipment, I didn't want to loose the opportunity to image this magnificent object as I will soon loose sight of it due to obstructions in the west. I am quite pleased with this image as a first attempt.

Exposures are:

Ha: 45x300"

OIII: 54x300"

SII: 60x300"

Total Integration Time: 13.25 hrs

120 Flats for each filter

70 Darks

120 Biases

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.
