Do not forget to leave money for the observatory, land with dark sky,

housing while you are there, and security.  Plus travel costs.

If you can find a used one, assuming a 40% discount over new, the savings might be significant. Almost enough for the observatory and land in a dark far away place.smile.gif

what about shipping? and ep's? at 6m fl, you'd need a 200 mm eyepeice just to get 30 power! must require 3 or 4 inchers.

At least this one will never be a serious purchase! But seriously, wouldn't a cloudy nights observatory be fun for cloudy nights? all data publicly kept, for CN members.

A full meter RC is too small for professionals and too large for most amateurs.

Why spend 500K on just a 1m scope when you can get a .6m scope and observatory for the same price?

Not at all.  Depends on what the astronomer's observational requirements are.  My club's observatory (pics in post above), houses a .6m RC and we are constantly involved with professional astronomers collaborating on various research projects from doing exoplanet confirmation and follow up observations for Kepler and now TESS to making time series photometric observations of variable white dwarf stars for the Whole Earth Telescope and the University of Delaware Astrophysics Department.  We also frequently collaborate with McDonald Observatory on many observations as well.  In addition, we frequently get asked by astronomers for time on our telescope when they have lost time on their preferred scope for whatever reason.  So I would certainly say there is more than enough for a "small" scope to do that helps the pros significantly.

These are not visual scopes - they're for imaging, photometry and spectroscopy. University of NSW in Sydney has one, used for teaching purposes in physics and astronomy courses.

Would one need some sort of Certificate of Starworthiness to sell scope time to professional astronomers?

Whether they're interested in what you have to offer is the real question, and that will depend on the instrumentation available on the backend, not just the scope and the mechanicals. It's not just about taking pretty pictures.

 

Results speak for themselves.

It was interesting to read this in that article.

 

"Alt-Az mounts are the choice for most modern professional observatories. An Alt-Az mount is inherently more stable than an equatorial mount since there is no cantilevered mass, nor are there any large protruding counterweights to create a dangerous hazard in a public observatory. An Alt-Az telescope is also considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. The mass required to make a rigid Alt-Az mount is substantially less, leading to substantial cost savings. Unlike German Equatorial mounts, there are no meridian flips to deal with; you can image continuously from horizon to horizon if desired. With no polar alignment required, the Alt-Az mount is far more intuitive to use than a German Equatorial mount."

Honestly I hadn't thought this link would generate such good response. Further if I was developing a private observatory it would probably be a hooker class instrument dedicated to low priority and time intensive projects.

The sort of investigations that while scientificaly valuble cant find donors.

But what about a CNO? and where to build it?

I presume it comes with the usual 25mm/10mm Plossls and cheap laser collimator?

Take a look at the PROMPT Array. The primary purpose of the array is to observe the afterglows of gamma ray bursts, but they get used for other purposes too. They are 16" RCOS OTAs equipped with Apogee Alta cameras on Paramount ME mounts housed in Astro Haven domes.

And all the extra land around the land with dark sky so you have a hope of the sky remaining dark in the future...

It's a CDK, so unlike RC it would be field corrected over a large sensor area.  And that means it is designed for 'imaging', whereas professional work would be focused on photometry or astrometry where RC would have the advantage of no lens elements, but bloated and oblong stars at the edge.

 

But for survey or discovery work - this would be well suited compared to RC.  It's large aperture and versatile, but slightly sacrifices throughput in UV and IR due to the lenses.

I just find it somewhat funny (ludicrous?) to see this scope advertised as if it were aimed at the general amateur market. At half a million bucks, you would think this would require a government contract and legislation to purchase. Just sayin'.

I think the price has come down. I recall watching a video of Dennis, I wish could could spell his last name, from Sky and Telescope, interviewing one of the founders of Planewave. It was a few years ago and I think that the price was over 600,000 dollars installed. 

 

I know more than a few professional astronomers who use telescopes smaller than one meter for their research.

 

 I also know one or two amateurs who use bigger telescopes for their hobby.
