posted Apr '21 doubles suggestion 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.


Lovely day today. Was just looking at the nearby (single) star...

The weather is improving. Clear skies are ahead. Sadly, the Moon is washing out the sky so we have to put galaxies and nebulae and faint fuzzies on hold. But double stars and variables are viable (assuming you can star hop to them).

Here’s a short selection of double and multi-star systems from my life list for your observing campaign. I found them interesting.

Please consider adding these to your observing list. Doubles are fun, easy, sometimes challenging, interesting, colourful, and dynamic! I look forward to hearing how you did! Holler if you have any questions.
