It is very important how you manage your data. So much shots, so much frames. They are full of hidden data that could be revealed later. The far we look the more we see. Each feint dot could be a galaxy far far way.
I use 2x2TB HDD to store mirror copy of all my data. I sort the photos by object and keep them in RAW. This give me the ability to reprocess the frames later with better techniques and software. I can also add more frames next year for example. That way I can track changes and get deeper and deeper filed as number of frames and total integration grows trough the years.

Here is some example of frames taken this spring and autumn of SDSS J1038+4849 ("A smiling lens"). Einstein gravitational lens. This is the farest object I have ever shoot - 7.6 billion light years. It is more then the half way to the edge of the observed universe. It is amazing how stacking technique can reveal details that otherwise are hidden into the 14bits and not easy to see. The blurry pixels that show the gravitational lens ark of the background galaxy are resulted just by few photons.

Almost there to the Smiling lens

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.
