Description

This is one of the images from my first night testing a new AstroMechanics ASCOM Canon EF Lens controller, with a Canon f/2.0 L lens and ASI1600mm.

This is an uncropped Ha image taken at f/2 and manually focused via the controller.

26x1m exposures with no processing other than levels.

Overall I'm very pleased with the result and the quality of the stars across the field with the lens wide open at f/2.

The lens was attached to the camera via the controller adapter and a ZWO mini filter wheel.

My earlier shot at long focal length is here:
