posted Sep 2020 doubles

Prepared my double star "bulletin" for September 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.

Here it is, a day or two before the full Moon and you're thinking you can't do any astronomy. In fact, planets, the Moon, variables, and double stars are up for grabs.

For Sep 2020, here’s a short selection of interesting double and multi-star systems from my life list for your consideration.

star	also known as	alternate catalogue(s)
HD 194192 Cyg	HJ 1510	SAO 49538
57 Aql	Σ2594 (Struve)	SAO 143898, HIP 97966
HD 197913 Del	Σ2725	HIP 102490
30 Peg	HJ 962	SAO 127453, HIP 110298
3 Peg	STFA 56 (Struve Appendix 1)	SAO 126940, HIP 106783

Have a go. See if you can split them and detect colour. I hope you'll share your discoveries.
