doubles for September 2019

Sent out my double star "bulletin" for September 2019 (with some appropriate emojis). It is a short list of suggested targets. I shared this on the RASC Toronto Centre forums. And I post here for all.

Hello!

Get busy. It's time to look at double stars 🌟🌞. Did you notice the statement in the RASC Observer's Handbook? It says that 85% of stars that appear to be single are in fact doubles or multi-star systems.

Here's a short selection of double, triples, etc. from my life list for your next observing campaign.

V340 Sge	H N 84	SAO 105104, HIP 96688
31 Cyg	Struve App A 50 or HJ 1495	SAO 49337, HIP 99675

Please consider adding these to your evening list. Doubles are fun, easy, interesting, and colourful! Sometimes they are rather challenging but these suggestions are pretty easy. I look forward to hearing how you did! Be seeing you.

Be seeing you.
