For the following solar disk images, Robert Pease reports: "I took these differential rotation solar disk images with the telescope shown. There was haze on a few of the days so some of the false color was introduced by the camera but other colors were introduced by the thickness of the clouds. August 30 to September 3, 2014."

For the following two images, Robert Pease reports: "I timed it just right. I stepped out onto my porch and set up and took these two pics of the X-flare (sunspot 1520) in progress. July 12, 2012."

For the three following lunar crater images, Robert Pease writes: "I took the attached images Tuesday evening (May 29, 2012) from my shaky porch near O'Hare. I used an ETX-90 with a Mallincam Signature camera. I recorded with a Sony VRD-MC6 DVD recorder. Playback was fed through a Mallicam frame grabber with still captures taken using AMCap software. The DVD recorder only uses 1/2 the lines, deteriorating the image from what I see on a small monitor."

In the following, all snapshot video captures of the solar disk were taken on September 25, 2011, the same day they were recorded on a Sony VRD-MC6 DVD recorder. A Lunt 60mm double stack, pressure tuned hydrogen alpha telescope was used with a Mallincam Signature camera, at 1/50 second exposure, f5.6. All recording was done at noon.
