Rho Ophiuchi - a 175 Megapixel Mosaik

Ok... where to begin.

This is the first real project finalized with my "Astro Tick" remote scope in the IAS Observatory at the Hakos Astro Farm Namibia.

Key fact:

18 panel
4,5+ hours of exposure per panel
more the 4700 x 60s subs
mosaic and imaging planned and executed with NINA (thank Stefan you're the man!!) [b] [/b]
stacking, processing in PI and PS

Gear:

Samyang 135mm @f/4
ZWO ASI 2600 MCC
iOpton HAE 29

Processing was a nightmare... stacking alone took more than 27 hours.
At some point, I had to stop messing with colors and contrast.

The image marked as final is reduced to about 50 megapixels check the original image if you want to see the full 175 mp image.

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.
