doubles for Dec 2019

Sent out my double star "bulletin" for December 2019. It is a short list of suggested targets. I shared this on the RASC Toronto Centre forums. And I post here for all.


I did a double header last night with the clear skies in Ontario and in Nova Scotia. Featuring double stars, of course! I popped out to the backyard with the little ETX for an hour or so while monitoring four imaging jobs being processed by the Burke-Gaffney Observatory. You too can check out double stars regardless of light pollution or the cold. Get out there.

Here's a short selection of easy double stars and multiples from my life list.
