doubles for July 2019

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

Smoke from forest fires may hamper your efforts and allow only views of the Moon and planets at opposition. Maybe brighter double stars could punch through the haze?

For July, here's a short selection of doubles from my life list, ones I find beautiful and impressive. I did not include terribly tight targets.

star	also known as	alternate catalogue(s)
σ CrB	17 CrB or STF 2032	HIP 79607
μ Her	Σ2220 (Struve)	SAO 85397, HIP 86974
HD 238823 Dra	PPM 36404 or STF 2300	SAO 30778
γ Ser	41 Serpentis	SAO 101826, HIP 78072
53 Oph	STF A 34	SAO 122526, HIP 85998

Consider adding these to your observing list.

Remember doubles are fun, easy, sometimes challenging, always interesting, often colourful, and dynamic!

I look forward to hearing how you make out. Holler if you have any questions.
