The Blue Horsehead Nebula with Rho Ophiuci and a serendipitous Comet C/2017 K2 (PANSTARRS) in the Scorpio Constellation. I didn't notice the comet until I processed the image! This is another capture from the Italian holidays from last week. The target was quite low on the horizon, even from Italy, and only visible for a couple of hours after sunset. Pretty much impossible to image it from the North West of the UK.
I acquired this image last week but I've been processing it the whole time without being ever happy with the final result, the version I'm uploading is actually one of the first I came up with. The main issue with the image is that it was some sort of experiment. I don't have enough slots for a green filter in my filter wheeI - it's mainly dedicated to nebulae narrow band with H-a, O-III, and S-II filters and R and B filters for the occasional star fields with synthetic green channel. So, I took 1.5hour for the B filter and 25 minutes with the R filter in 60s subs and I created a synthetic green channel with 50/50 B and R. I'm not fully happy with the results, in the end, I think I over-processed the image a bit too much...

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.
