I was really happy with how this turned out as it was my first ever target when I started Astrophotography. This is a culmination of lots of work on the RASA and custom building M68 mounts, filter sliders, and tilt/backfocus hardware to achieve good results with a full frame camera. At f2.2 it is a challenge for sure.

I was really impressed with the results here of the Astronomik MaxFR 50x50mm square Ha, Oiii, Sii 6nm filter set which produced some really good data. This was my first images taken with this newer filter set. This was processed in PixInsight to do general linear work and noise removal and color enhancing was done in Photoshop.

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.
