Observer Comments

Image Capture DescriptionThis second day after returning from my NYC and Princeton trip was a much more typical day. I'd left the Askar out on the pier and ran another side by side comparison. In these conditions, the "single exposure" lucky imaging of the Seestar delivered the better quality. The "lucky imaging" filter in Seestar, based on accepting a percentage of images, simply wasn't discriminating enough and the stack was inferior to a single image.
