your monthly double stars

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


I don't know why I bother, really. I mean, we're not going to see stars at night until May 2019, right?!

Anyhoo, if you're lucky to get the odd clear night between now and then, pop into the back garden or onto the deck and have a look. Double stars are visible from anywhere, even in the city, and any time, even with a bright Moon.

Here are some suggestions:

Happy hunting. Let me know how you did!

Frank shared his observations on the RASC forum on 29 Dec '18.

He also pointed out a mistake in the Mesarthim or Σ180 entry. It should be γ (gamma) not lambda.

While investigating I found I had quoted the SAO number for λ. gamma's alternate catalogue number should be SAO 92681.
