Just trying to find out what would cause the irregularity in the bigger stars that I'm pointing to in the screenshot. Image is a 120 second crop from the Pelican Nebula, shot with a 533mc pro, Zenithstar Z61, Z61a flattener. It's the first time I've ever seen this irregularity in a star with the camera. Camera is about a month old. Images from a couple nights ago, of the same region, do not show this at all. Nothing has changed in the hardware / setup.
