Celestron 8″ SCT Telescope
The 8 inch Celestron telescope is the workhorse of my observatory.
I tend to be a brand loyalist when I first make a purchase, making sure as many products come from the same manufacturer. Maybe it’s a misguided belief that if they all have the same name on the gear that it should all work better.
