> The simple spectroscopy
I recently bought a pocket spectroscope for laboratory use. You can find it at Ali for 5$. It is with glass prism and well build. So I did some test to use with a telescope but did not
bring any good result, so I cut it and strip the optics. Left only the prism and place it inside a eyepiece projection tube. Also place a 17 mm plossl in front of the prism. Result is
a home made spectroscope that I can use for bright star spectrum and light pollution analyses. This task well fitted to my new Vixen VMC110 as the flap mirror help a lot of
locating the targets. Below are my first tests
This is a image of Betelgeuse. The white color is IR spectrum as expected from a Red giant:
This is Sirius system. You can see that most of it is a blue light as expected from a Blue hot giant:
This is led street light spectrum. It is not good that it emits in all the visible spectrum:
This is sky pollution background. Simmilar to the street light spectrum.
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.
