Had another imaging session here, with the APM 80mm F/6, ASI178MM, and alternatively the Lunt Wedge with Baader Solar Continuum and Astronomik L filter to block the IR leak, or the Lunt Ca-K module. Seeing was pretty decent. I stacked 400 out of 4000 frames using AS!3, except for the prom shots, where I used 2000 out of 4000, the seeing was stable enough to allow that. Postprocessing was with ImPPG and Gimp.

Thanks, everyone! Curious to see how eclipse images in Ca-K will come out

Nice shots, Michael. I'll be imaging in CaK too with a similar setup right up to totality and then I'll be switching to natural light to try to capture the corona.
