Testing Meade LX 85 8" ACF for DSO-30 sec.x1-R channel only-ASI 1600 MM-Pro

Testing Meade 8" ACF for DSO for the first time. I did not get a proper adaptor for OAG for that time (I did finally figure out it today- done), so no autoguiding, no darks, no flats. The biggest surprise for me (I had no experience with large SC) was the enormous quantity of light that the scope accumulated in 30 sec. only (it is f/10, the reducer is still on the way-I am always cursed with a long delivery time for reducers and flatteners). I used R filter only and one shot only as well. Histogram is almost full with the signal, I imagine that with f/6 I would have A LOT more signal. Some elongation of stars are evident due unguided shot (with focal length of 2032 mm good polar alignment and autoguiding is a MUST), but I cannot see coma on the corners (Advanced Coma Free scope proves to be true). I am impatient to use both reducer and OAG, but I will leave soon for weeks business trip, so the DSO have to wait. The weather is awful again, heavy rains all the week long.

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.
