> NOWADAYS IS HARDER TO SHOOT LONG INTEGRATION TIMES WITHOUT GETTING ANY SATELLITE PASSING TROUGH THE FRAME

Satellites, cosmic trash or UFOs, the moving spots are everywhere on the sky. Typical satellite behavior is to reflect sun light. It should be yellow or white and could fade and shine due to its rotation. At Saturday I was trying to make a stack of 50 frames of 30 seconds of Horse head nebula. I was surprised that during the 25 minutes integration I could count around 7 satellites passing trough the field of less then a degree. One of the objects was spinning very fast leaving a doted line on the frame. Below is a single frame with 3 satellites passing at the same time in front of the horse head nebula. The lines are not straight due to the wind vibrations. I assume that those are satellites but in fact as I am not sure those objects are officially UFOs :)

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

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.
