The Fishhead Nebula - A deeper SHO rendition with RGB stars

Revision title: NXTed & BXTed version.

A streak of clear nights agin with Moon illuminated over 50% at the beginning but waning.

So I setup all rigs but unfortunatelly I recognized when going or the first OSC shots in this project that once again a ASI2600 cam was having an issue with leaking oil on the sonsor glas.

I am really not keen to fix another one...had that issue before with my first mono cam which was exchanged finally after it leaked a second time and I want not to go through all this a for another time...

But there are still RGB filters installed in one of the two EFWs. Makes things a bit more complicated and time consuming but that was the workaround to get RGB stars for the whole field!

The cropped version was due to cropping out that oil stain artefact which forced me to give up a substantial part of the FOV.

After collecting RGB data seperately with the mono cam I was able to bring in RGB stars all over the initial field of view.

In the end integration time was in total way above 40 hours...a new high watermark for me :-)

Thanks for watching!

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.
