Double stars manage to punch through the suburban murk of light pollution and put on a show. They only need steady air, not dark skies, and their colours can be beautiful.
I got quite interested in them about a decade ago and went through all the references I had (mostly Sky Cataloge 2000) looking for the most likely candidates for my C8.
I was fairly restrictive, they had to be bright enough for city viewing, not too close for resolution, but not too wide to be interesting. Even so, the result was a list of 346 pairs which I observed over the following year or so.
But the end of it I'd learned a lot about my scope, my eyes, and the limits imposed by the atmosphere.
Regards,
Chris
