Setup for imaging Luminance/Ha through the Celestron C80ED 80mm refractor and DSI Pro II up top,
and through the 170-500mm Sigma APO lens and DSI II (one-shot color) below.
Mounted on and guided through 8 inch LX90 and DSI Pro.

Lens assembly took the place of one of the 5 pound counterweights.
Setup required 1.5 pounds of counterweight on the back to keep the system from being too nose-heavy.
