After some time of abstinence I wanna show you my result. Done this week with the Canon EF 200 at f/5 and the Moravian G2-8300. It is a LRGB, 8x600s for every channel.
I am from Austria/Europe, this southern object is very difficult to capture for me. Here you can see the rising of Antares. Some minutes after this I startet to exposure. 3 hours later it left the scene!
