posted Aug '21 doubles list

Prepared my double star "bulletin." It is a short list of suggested targets. I shared this on the RASC Toronto Centre forum. I post here for all.


The Moon is bright again. Jupiter and Saturn are not to be missed and easily bunch through light pollution. So do double stars. Assuming you are able to locate sparklers to star hop from or align on, you can have a ton of fun.

Here’s a short selection of doubles from my life list, ones I find interesting and impressive.
