posted July 2020 doubles

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


I hope you enjoy my periodic posts with interesting and fun double stars. I think they are impressive, colourful, and beautiful. I particularly like how they punch through light pollution.

Here's a short selection from my life list. I did not include terribly tight or faint targets.

Please consider adding doubles to your observing list. Often they are easy. Occasionally they present some challenges and might require repeat viewing.

I look forward to hearing how you did. Holler if you have any questions.
