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.

For my last trip to the Rodopa mountain I decided to cross the limits and to target an object that is hard to believe that a non-professional equipment could catch.

While cleaning up my PC I found sequences of shots of Virgo galaxy cluster taken during springs of the last 2 years. Those were attempts to shot this object, but I was not satisfied with the result and left them.

http://www.deepskywatch.com/deep-sky-hunter-atlas.html This is an amazing resource. Detailed atlas of all the sky with NGC and IC objects.

Reading a new product that claims to be 100x time more powerful then conventional telescope, I realise that this is just an astrograph with a digital camera that is doing stacked images and show them trought eyepiece or App.
