Description

The goal this evening was to test the supersharp Nikon 600mm (f4) with ASI2600c. I think the image came out great despite poor guiding in some subs as the guide scope's FOV was disturbed by our garage roof . Nevertheless the lens is highly suitable for imaging and I am going to continue trying it out with 2x converter for a FL of 1200m (f8). Enjoy....
