Discussion Overview

The discussion revolves around the concept of building a mobile observatory, focusing on design considerations, functionality, and personal aspirations related to such a project. Participants explore various aspects including leveling, vibration dampening, and comparisons to existing mobile observatories.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express a desire to build their own mobile observatories, discussing personal plans and modifications to existing vehicles.
  • Concerns are raised about how to level the observatory, with suggestions that it may not need to be perfectly level but rather stabilized using screw jacks or hydraulic legs.
  • There is a discussion about dampening vibrations, with some proposing that the telescope should not sit on the trailer itself, but rather use a pier that extends through the trailer floor with self-leveling legs.
  • Participants debate the definition of a mobile observatory, with some asserting that certain examples provided do not meet their criteria, while others share links to what they consider proper mobile observatories.
  • Technical details are discussed regarding the need for the pier to be stable and upright, and the importance of allowing for adjustments in elevation and rotation for proper alignment.

Areas of Agreement / Disagreement

Participants express differing views on the design and functionality of mobile observatories, particularly regarding leveling and vibration control. There is no consensus on the best approach, and multiple competing ideas are presented.

Contextual Notes

Participants mention specific technical solutions and personal preferences, but there are unresolved details regarding the effectiveness of proposed methods for vibration dampening and stabilization.

I want one too. Maybe i can convert my Dad`s mobile caravan. atleast i can have a nice hot brew while working!

I can`t see how he`s going to level it.
 
Leveliing isn't the tricky bit; I wonder how he's going to dampen vibrations.

I don't think it would have to be levelled accurately--just stabilized. Screwjacks or hydraulic legs on the corners could do either.

Neat idea, for sure.

edit: Dave, your post wasn't there when I was doing mine. As for the vibrations, the aforementioned legs could consist partly of automotive shock absorbers or spring-loaded telescoping segments. I don't know which specific vibrations you're talking about, though. All that I can think of right off are wind and the observer's own movements inside. I don't assume that he'd be using the thing right close to a highway.

What’s that! That’s not a mobile observatory. Now http://www.rcopticalsystems.com/rc_cine.html is a mobile observatory!

BTW, the 20” Ritchey-Chretien alone is $48,000

True

Photography on a windy night, forget it :mad:

I'd like mine with the optional missile launcher, please. :-p

I was thinking about the vibrations bit this afternoon - the solution is that the telescope doesn't sit on the trailer! The pier just protrudes through a hole in the floor and has self-leveling hydraulic tripod legs folded into the bottom of the trailer. At least - that's how mine's going to work. :biggrin:

It looks like the guy with the goggles is getting a direct feed from the CCD at the RC's prime focus...or is it just wishful thinking?

I noticed also that the "little" (about 12") 'scope under the RC is operating with an off-axis aperture mask. Custom-made with top-quality materials - black construction paper and gaffer's tape. :-p

Yep, protruding through the floor is the way to eliminate vibration from the trailer. You just need a method of jacking up the pier and locking the base to the underside of the trailer frame so you can move the trailer.

There're really no need to level the pier accurately, it just needs to be upright enough to remain really stable. The trick is that the head of the pier must be able to rotate and your mount needs to be adjustable in elevation. With these two motions, you can polar-align, no matter how you park your trailer.
