My name is Raoul van Eijndhoven. I only started recently (2012) with Astronomy. 
I use 2 different telescopes, a Skywatcher SkyMax 150 & an Ascension ED80 APO Triplet. For imaging I use a modified Canon DSLR  camera. The modification is that the IR filter has been removed.

With my current setup I am able to take relative long exposure images of about 4 -5 minutes. Longer does not make much sense due to the amount of light pollution in and around our town.
