IC4592 LRGB - The Blue HorseHead Nebula's Horse Head

This was intended as a field test for the new Chilescope's T5 telescope, however the subject choice probably wasn't a wise one. Still, a test is a test is a test. Truth is I was itching to have a go at this nebula for quite some time (and all previous attempts resulted a neat zero) that I jumped at it once I had a choice. Plus, I would be testing the LRGB response of the new system. End result isn't too satisfying, possibly because of teething issues with what is tricky telescope to set up. This said, I'll probably restrict my usage to NB imaging. These two semi-circular halos at the upper left and right corners look very much like some off-axis reflections from the corrector (different size for different filters). Add to that I somehow expected a bit more from an 8" f/3 system. Well, at least I didn't wasted a lot of dosh on it! Given the limitation of exposure, overall quality of the L frame and the interloping satellite I decided that the middle way is the best way to downsized so the release image is 50% of the original one, not that the actual resolution is going to suffer anyways...

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.
