> BULGARIAN ACADEMY OF SCIENCE ASTRONOMY CALENDAR FOR 2016
You can find my last DSLR Astrophotography article in Bulgarian at page 76. I am sharing my last findings for this publication, Specially written for the Institute of Astronomy. My research was made during the last year in searching of should I need to upgrade my camera and witch one would be the best for me. After writing the article I do upgrade with Pentax k-5 – the best camera from Pentax. It was a great improvement.
Even the new K-3 has lower http://www.dxomark.com/ score and thus I do not believe that the higher number of Mpix will show much improvement as most of the current lenses are best around 12 Mpix resolution.

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.
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
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.
I am so impressed with the K5 ability to quickly gather signal from nebulas (Quantum efficiency) and galaxies, so I decide to take one more K5 and to remove the IR-cut Filter of the old one.
