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

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.
This capture shows bright plages with dark filaments, granules and spots
on the "surface". A small prominence can be seen.
