Re: Telescope Aboard?

The OP was certainly talking about taking it to land in the dinghy. That's part of his challenge.

Seems like the Dob is still the most robust option for a large aperture machine as it will be the easiest to re-align and clean. The open truss concept is a good one.

I'm not sure how a compact Schmidt-Cassegrain would hold up, but they are very sexy.

Here's a link to the miatascope, A compact dob's telescope that fits in the trunk of a maita.. Think someone made a 15" one too... so sweet...

Yes I want one too!!

I say go build or buy a collapsible dobsonian reflector.

If I had a house away from light pollution in the desert, I would get one of these. I did use someone else's at the Grand Canyon and it was impressive.

I'm sure the islands are far enough away from the lights to see a lot of stars.

The next telescope I get will have the GPS finding capability. There are also ones that interact with the iPhone or iPad too. I would think that a pelican case would let it arrive safely anywhere you take it.

There is a telescope that is inside its own revolving observatory in Saipan,I belive it was built by the guy that started Flying Tigers(DHL) and you can see some incredible things due to the fact that there is no light pollution to speak of,It also sits at a few feet above sea level,unlike its counter parts in the not to far off Sandwich Islands to the east,anyone can just walk in and start using it,the guy that built it died in a plane crash at sea and he had lots of children across the Pacific Ocean that were angry with one another and his property was like, open to the public! ...A pair of binoculars work great also because they are like you say"far enough away from the lights"...

Hmmm. Yes, I think I said that already:

(and before anyone says it - yes - I understand that I can't use such an instrument aboard).

You can still see plenty of beautiful nebulas and the moons of planets with a compact reflector. Refractors (one lens) have better light transmission for the same aperture but reflectors (two mirrors) are smaller, which is what you need.
Yeah, this is sort of what I'm thinking. I'm interested in deep-sky objects, as the planets (at least the ones that are worth looking at in an amateur scope - mainly Jupiter and Saturn) I can see anywhere. I think a decent 6" reflector (or Cassegrain) might be the way to go. I haven't looked at scopes in a long time, but noticed on a recent perusal that it's hard to find any (other than the Dobsonians) that don't have go-to gizmos. I never have been a fan - preferring instead to "star hop". It'd be nice if I could save some money by foregoing that nonsense and put the money into better optics.

I have a pair of x70s (for astronomy) and they are difficult even with a stabilized tripod on land - so I agree with you.

MiataScope
What I have now is essentially a "miatascope". But even that (with an 8" mirror) is bulky and quite heavy. Then there are the trusses and the accessories. Maybe I ought to just re-think what I have and come up with an easier way to get it on/off the boat.

Think of it this way, the members who had a really great time on New Years? Might still be a bit impaired. (G)

A beautiful instrument, indeed!

Re: Telescope Aboard?

With getting it on and off the boat don't forget the tripod.
Big, clumsy and picks up sand and dirt.

On the positive side, there have been so many nights on island beaches far from light pollution that looking up you just see an ocean of stars. A telescope would be magnificent.

And there would be a line up of cruisers wanting to have a look.

"there would be a line up of cruisers "
Isn't that the "How to make money while cruising" thread? <VBG>
