Coulter 14.25",F-5 Newtonian Reflector Telescope (Mobile)

I am using a Coulter 14.25", F5, newtonian reflector with a one twenty fifth wave front.Mounted on a Astro Physics 1200 mount with encoders. With a Cave Astrola rotating rings and a JMI 3" EVXTNM focuser with motor. Mounted on a trailer to go to dark viewing sites.
From changing the wood floor to plastic resin planking on the trailer. Upgrading the mount from a sixties era Cave Astrola drive to a 90s era, Astro Physics 1200 encoder mount. I still retained the pier, fiberglass tube and the Astrola rotating rings from sixties era. It has been on this home made trailer since 1978. Recoated the primary and secondary that I have used, since its purchase in 1977. Since that time Cave Optical Co. went out of business. The 14.25 inch, F-5, one twenty fifth wave front primary made by Coulter Optical Co. went out of business, not long after they started making Dobsonian primary mirrors.It was a time when the Coulter 14.25", F-5 primary was their leading sale item. The most recent up grade was the JMI 3" EVXTNM focuser with motor.
