NGC 5965 and a very faint NGC 5963

This galaxy pair is my last shot of the 2021 galaxy season. Its time for the shorter focal lengths to return.

I am just going to use this space as a scratch pad to make some notes for me to read next winter, since I am sure to forget what I want to do differently.

Bob, here is what you should try when next imaging galaxies:

1) Everyone that you follow who also live in poor bortle zones do not use a light pollution filter for luminance. You know that totally clear filter that came with your LRGB set which you laughed at and almost threw away? Put it in your filter wheel and try it. Shorten the luminance exposure duration to lessen the impact of seeing. According to some much more experienced astrophotographers, your SNR will improve.

2) Learn to not hate collimating your telescope. Its not tedious. It doesn't raise your blood pressure. Its fun, enjoy it!

3) Banish the 14th Yule Lad 'Camera-Turner'. Somehow the camera ends up rotating a random number of degrees between nights even though you have left everything set up for a week. This reduces the effectiveness of your flats, which forces you to blacken the background too much. Consider a rotator (?). This may force you to abandon the Celestron 0.7x reducer since you will not have enough back focus for the rotator and filter wheel.

4) Learn how to protect stars in processing. They end up looking too harsh.

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.
