Mar 2020 doubles

Sent out my double star "bulletin" for March 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'd like to share some double stars for your viewing enjoyment. These are interesting and not too tight. Hopefully the battleship grey skies will go away.

Doubles are fun and easy! So add them to your observing campaigns for variety and a little bit of eye candy. They are fantastic to show are star parties and lend themselves to good science discussions. They withstand light pollution.

If at first glance, you don’t see anything obvious, keep warm and keep staring.

Be seeing you.
