My William Optics Fluorostar 91 telescope

William Optics Fluorostar 91mm

I recently acquired the William Optics Fluorostar 91 as both a visual and imaging telescope. I selected this model because of the excellent optical quality, large number of included accessories and the avaliability of multiple options of field flatteners from William Optics. I also wanted a little bit more aperture than your standard 80mm while still staying around 500mm of focal length.

Assembly

It’s just a tripod, it is pretty straightforward to set up.

  1. Spread out the tripod legs and set the tripod on roughly level ground with the stud aligned with North. If the ground is soft, it will help to put something underneath the tripod feet or fit some large washers onto the feet.
