12/2008 - Present (Long Focal Length)

Here you can see my first "real" imaging setup. The main telescope is an Orion 8" with the SkyView Pro mount. On top of the main telescope is the Orion ShortTube 80mm guide scope.

I made some modifications to the 8" telescope including masking the primary mirror's edges to avoid unwanted diffraction spikes, lining the inside with black felt, tuning and regreasing the mount's gears, and adding autoguide capabilities.

I still use the telescope, but have upgraded the mount to an Orion Atlas.
