Bob Vanderbei is a professor in the Department of Operations Research and Financial Engineering at Princeton University. He is an amazing astro-photographer and a club member. His photo of Mars below taken at 3:15 a.m. on October 6 makes you want to visit the planet and perhaps make a stop at the resort on its southern tip!
- Bob’s telescope is a 4” f/5 Takahashi FSQ-106 refractor.
-
He uses it for imaging when the desired field of view is too large for his 10” RC. I does not use it as a guide scope.
-
The mount is a Takahashi NJP Temma-II equatorial mount.
-
His current astro-specfic camera is a StarlightXpress Trius SX-694 CCD camera.
-
It’s not a color camera and that’s why he has a filter wheel.
