doubles for Nov 2019

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


The Moon is bright again. That means it is doubles time!

Here's a short selection of double and multi-star systems from my life list for your observing campaign. They are all pretty easy. Below are some targets best viewed in November.

Remember doubles are fun, easy, sometimes challenging, always interesting, often colourful, and dynamic! If at first glance, you don't see anything obvious, keep staring. Sometimes a dim companion will emerge when the seeing conditions allow. That's always exciting!

Share your observations. Keep warm. Be seeing you.
