This is the beginning of my research on how dark the sky could be and what is benefit of a dark sky for astrophotography. I was inspired from those 2 sites. First one presents mathematical model of how dark the sky is. Orange is for very polluted sky, for yellow – you do not see the milky way, for green – sky is polluted of some degree up to the zenith, for blue – there is a shining at the horizon and grey is for a dark sky. The second map is for how much light each village emit. You can switch between the years.

I went to Kara Tepe at the heart of the Rhodope mountains 1600m above the sea level. It is in the grey area and the sky was outstanding. You can get great shots with ease. Full if stars and details.
I will continue my research and use such locations to shoot faint objects. Here are some new photos of Lagoon nebula (40x30s ISO 25600) and M22 cluster (1x30s ISO 25600):




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.

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.
