42 x 111Sec exposures for a total of 1.295 hours of light

G26 color camera on C8 with 0.63 reducer and CLS filter
PHD2/Orion Starshoot guiding on 80x400mm refractor scope with ST4 "on mount"
Polemaster exact NCP alignment procedure
EQ6R PRO mount
2 Inch Astromania Adjustable Helical Back-Focuser
Starizona magnetic single filter tray

AST capture with synscan GOTO hand controller only
deep sky stacker and PS

This is a random shot to ascertain back-focus with C8 SCT and other items of concern

(RANT) Took this just prior to getting N.I.N.A. so no plate-solving was used for goto alignment because I can't seem to find anything in the sky with this narrow FOV deep reach telescope!

I also have some small vignetting but have an Astromania 2 inch Helical Micro Focuser which only needs to be twisted ever so slightly to fix this 100%. I measured 105mm using only a scale and my eye to the best of my inspection - but am a little off I guess.

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.
