posted late-Nov 2020 doubles

Prepared my double star "bulletin" for Nov-Dec 2020. It is a short list of suggested targets. I will share this on the RASC Toronto Centre forums. And I post here for everyone.

hi,

The Grey Months are upon us so this may all be for naught. But if you find yourself with clear conditions over the next couple of weeks, after looking at the gas giants, then try out some easy doubles for fun. For Nov-Dec 2020.

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

Be seeing you.
