found new version of MCU

After a bit of digging, I found a new version of the MallinCam Universe software, version 5.0. Need to be on groups.io to get it... Weird. Happily, the app now writes out an AVI file correctly, proper playback in MS Films & TV and VideoLAN VLC. But the crop feature is not used, still, during recording.

watched the splashdown

Watched NASA astronauts return to Earth in the SpaceX dragon. Wow. I hadn't thought about it... 45 years since a splashdown for the United States space agency. A pretty impressive mission overall.

posted August 2020 doubles

Sent out my double star "bulletin" for August 2020. It is a short list of suggested targets. I shared this on the RASC Toronto Centre forums. And I post here for everyone.

The Moon’s bright again. Don’t despair; do doubles.

Here’s a short selection of double and multi-star systems from my life list for your observing campaign. I found them interesting.

An interesting quality of double stars is their resistance to creeping light pollution. So, have a go. See if you can split them and detect colour. How different are they in brightness? And share your discoveries.
