All,
Our Obsession telescopes when combined with the LeNhance filter, the tracking system of ServoCAT, and a Mallincam Video Cameras make astrophotography more than just possible.
And our large mirrors only require a brief time for dim objects.? I often see astrophotographers taking hours and hours of capture time.? This image required a whopping 200 seconds.? The Mallincam video camera does an alignment of each frame during stacking so the "fault tolerance" of the camera enables DOBs to participate in astrophotography AND EAA (electronically assisted astronomy).
Here is the Bubble Nebula from December post processed with Pixinsight (they recently updated and enhanced the software) taken with my UC18 and a Mallincam DS10cTEC.? I also remotely control my telescope system with Stellarium wirelessly from inside my house.
