Right now the camera is fully capable of capturing the scarce H-Alpha light from the deep universe.
Last night I went out for a test aiming the camera with 180mm lens at the center of Cygnus. Aperture is set to F3.5 to limit chromatic aberration. Tracking is done with AstroTrac TT-320X. Total exposure 33 minutes.
