>Betelgeuse grand minimum is not that grand
For a few months from now Betelgeuse (Alpha Orion) dim so much, that it looks as bright as the stars in the Orion belt. This is not so disturbing and does not mean that cataclysmic events are happening with it. This brightness lost is mostly in the visual spectrum. The star is still shining as the brightest one in the constellation, when looked into the inferred spectrum. Below is comparison of the Orion constellation seen in visible and inferred light. In visible Rigel (Beta Orion) seems to be the brightest star. However in Inferred, Betelgeuse outshines it quite a lot.
We all hope that this star will explode in near future, so we will have some nice target for shots and research. For our luck it is just far enough not to cause any troubles :)

Recently I started to use Siril for processing my images as I was shown a new tool for star extraction Starnet++.
Since beginning of 2023 Chat GPT was launched as a human language model and start a new era of technological development.
As may times I said it is essential to keep all your shots over the years, as you can go back and reprocess them.
Make new discoveries or improve the resulting image quality.
When we have a new newton telescope we shroud avoid touch the collimation of the secondary mirror as we may get into troubles.
