[ATMoB-discuss] JMI Wheely Bar question

[John Boudreau]

Well known astro imager Rob Gendler used a 12" Ritchey-Chretien/AP1200 mount setup on JMI wheelie bars for years in Connecticut. He kept the scope in his garage and wheeled it out in his driveway for imaging, lining it up on marks place on the asphalt to get a quick polar alignment. Not sure if he still uses that setup at all, as he now has a remote observatory out in New Mexico.

Here's his driveway setup:
