M106 - double exposure without guiding

This is the result of my first try to combine RGB images taken with my "old" Altair 183C and my ZWO ASI1600MM Pro camera taken in one session. I used my 8" RASA to gather Hα images while the Williams Z61 obtained RGB images with a 0.8 focal reducer. Since both of my scopes were "used" there was no guiding possible, hence I chose 2 minute exposures which theoretically the Losmandy mount can handle. I believe this has been pretty well proven (with focal lengths of around 400mm of course!!) that it is possible.

This is my first try to combine these 2 sets, I still have to get some kinks out of the process, but it looked good enough to post it.

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.
