posted suggested Feb '21 doubles

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


Oh look. Clear skies. Yeh! Oh look. It’s nearly a full Moon!

Well, at least you can try for some double stars.

Here’s a short selection for February 2021 of double and multi-star systems from my life list for your observing campaign. I found them interesting.

Can you split them? What subtle colours do you see? How different are they in brightness? I hope you will share your double discoveries with us.

Onward and upwards.
