Finally had a chance to fix the sensor tilt on my Hypergraph 8.

With 90% full moon, and a reluctance to observe past 2am (severe dew), I though it would be a good test of an f/3.2 system too see a) whether I had managed to reduce the defocus caused by the tilt and b) just what SNR I could collect on a relatively bright target under challenging bright and humid conditions (beautiful moon halo from 1am).

Overall I am pleased with the outcome, although it will still need more data. Nevertheless, I am impressed with the performance of the TS Hypergraph 8, now that I am beginning to get the optical train into some sort of shape. When I purchased it, I was concerned that it might prove to be a bit of a dud - not many images using this scope on Astrobin - but so far I have been impressed.

I did dial up the colours on this one - but, hey, its NB imaging and you can have any colour you like. And besides this really only started out as an optical alignment test.

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.
