Like many other threads posted here in this forum, I’ve finally decided to start my “large” telescope project after years (decades) of procrastination, design modifications (indecision), life changes, etc. I’ve collected various pieces and parts over the years (some dating as far back to RTMC swap meet acquisitions in the early 80’s), made numerous iterations to drawings and plans over that time, even talked about this for years here on CN. But I’ve never actually pulled the trigger and just started building it. Until now…
I’ve always been a fan of big fork mounts. Likewise, I’ve always wanted a big C14 for the iconic reputation of the scope, and when OPT had a screaming sale on New C14 (non-HD) OTA’s a couple of years ago it solved that problem. However, what to do about the mount? My challenge is to design and build a fork worthy of the mighty C14.
Some of the design considerations for my project include:
- Visual use only: As described in a different thread, I have no interest in AP. This is purely a visual system, however that does not mean I can compromise on quality. The mount needs to be rock solid, and I am a stickler for mechanical details which also adds to my end user experience IMO.
- Built in Stages: Initially Alt-Az to get the system into operation ASAP. But can be upgraded to an equatorial configuration later during the summer observing down-time.
- Multiple OTA’s: I’m looking to build a complete observing system. The C14 will be the high power OTA, but I want to tandemly mount a large, low-power RFT (with Binos) for wide-field work later on as well.
