Nice photo! Any idea how long it takes them to do one revolution around each other?
Some folks say if it’s a binary system, it would take 100,000 years, if I’m not mistaken. Then again, others say it’s just a visual double star system. Either way, they’re pretty spectacular though an eyepiece or through a camera.
Btw, don’t look too close, the tracking was bad at the time as I was still in the process of fine tuning the scope alignment.
