Wow. It was 3 years ago, I think, that I first started bombarding you with double star targets during bright Moon passes. I hope you're OK with all this because I have a couple more I would like to share. :-D
Double stars punch through bright skies so you can observe them any time, anywhere!
Here's a short selection of doubles from my life list, ones I find interesting and impressive. I did not include terribly tight targets.

Add doubles to your observing list. They are fun, easy, sometimes challenging, interesting, colourful, and dynamic! I look forward to hearing how you did! Share your log notes.
