Radio Show Interview; D850 DSLR Moon & Jupiter
Posted: 24 June 2018
Saturday morning, 23 June 2018, I was interviewed on the live radio show "Rosie on the House". For about 40 minutes we talked about Oracle State Park, my local IDA International Dark Sky Park, astronomy, light pollution, and more. The interview is available online for your listening pleasure. I was on during the 7 AM hour of show.
The daytime temperatures in Oracle have been over 100°F for several days. Saw this antelope squirrel Saturday morning. He knows how to stay cool in the shade!

I then decided to try some test video recordings using the D850 DSLR (DX, 1080p, 120fps) of Jupiter using eyepiece projection 271X. This is a stack of 84 video frames using Lynkeos, 1/160sec, ISO 2500:
