RASC-TC Double Stars, Unnoticed Treasures

[@richardwarren1718]

Sadly we lost you this year (2023) Blake. I really enjoyed your presentations on your own as well as with Chris and Shane on the Actual Astronomy Podcasts. Just checked out Eta Persei a few nights ago while zeroing in on the Double Cluster in Perseus, the Alpha Persei Cluster and the Andromeda Galaxy. You're missed already buddy. Thanks for the inspiration and knowledge. Now rest awhile. 🔭🌌

The Cambridge Double Star Atlas has great double page star charts and 2500+ multiple star system up to 7.75 magnitude primary and up to 13 magnitude secondaries. 80% of the stars can be seen with a 4" scope and I use an apochromatic 102mm/4" up to 450 magnification. My 6" reflector has custom mirrors on it with the primary 1/12th wave and a Strehl of .98 ratio , but I will use it with my AZ Pro that holds two scopes for outreach, but otherwise it gets used for AP. Just easier to use the smaller scope, but if I have a smaller target I'll use the 6" to 400x, but I need my 2x TeleVue Barlow. I often use orthoscopic eyepieces down to a Baader 6mm Ortho.
