posted late-Dec 2020 doubles

Prepared my double star "bulletin" for Dec '20-Jan '21. It is a short list of suggested targets. I shared this on the RASC Toronto Centre forum. I post here for all.


Keep an eye on your weather tools and if we get a rare clear night, bundle up and get outside. Any astronomical observing is better than TV. Here are some fun and interesting double stars which are not terribly tight or faint.

Doubles can punch through some light pollution and you can enjoy while the Moon’s out. And while you’re checking out planets like Jupiter and Saturn before they fade away or Mars as it gets smaller and smaller.

Be seeing you.
