say you had 100K to buy equipment for an observatory. what would you buy and why? 

 

 

and go...

You have to give me the 100k first!

That's not enough greenbacks..

Just the mount & scope would close that door.

 

Maybe more like $250K.....

I will use the most of it to move west, away from NE Ohio.

As you said equipment for one and not to build it, I'd get a good mount and a scope that is too big to be practical / convenient used otherwise.  Hard to go wrong with a big Dobsonian if just for visual.  But then I like refractor views too, so for me might be a big refractor, and a big Dob in a shed next to it.

$100k wont go far (here in Australia).

Maybe a converted shipping container (converted to a mobile observatory) that can lifted using a big fork onto a truck.
The most capable robotized GEM I can get.
A 1m f2 Newtonian with a very large chip astrocamera at prime focus.
A slab ready to use in the Barrington Tops NP.


In reality I'd rather spend the $100k on a nice boat, a new Prado or Pajero and a camper trailer , and spend the change if any on a 14" f2.8 Newtonian and oversized GEM to carry it.

I would not build an observatory,

but use instead for astro travel.

My negative experience with an observatory is

 

you build it and LP will come   confused1.gif

 

but I would suggest you ask this question in the Observatory forum

Since I already live at a dark site...

 

I would buy the biggest mirror and secondary I could find and make a giant steel dob on a fixed mount, with a pivoting observing seat attached to the eyepiece position.

 

Mirror: 20k

Secondary, focuser, and other bits: 5k

Mount and tube: 5k

Motors, etc.: 5k

 

Then I would buy two 8" fast apo lenses and make a wood binocular telescope, also on a fixed alt-az mount.

 

Lenses: 10k

Other bits, tubes and mount: 5K

 

Then I would make a fiberglass cover for each scope, perhaps with a jig to help move it out of the way to observe.

 

Weather covers: 2K

 

Finally...

 

Eyepieces and filters: 15K (need pairs of everything for the bino scope....)

 

Total: US$ 67,000.  

 

I'd keep 10K for things that might come up later, and donate the rest to charity.

And what’s your motivation for asking this question? There are deeply held beliefs on each bit of equipment that goes into an imaging system that often erupt into flame wars. So you should do your own homework unless you need actual guidance on spending this kind of money. You could use the following guide as a reference-

 

Mount 15-55k

Scope 15-30k

Camera 11-15k and 2k for the filterwheel

Filters up to 8k

Focuser/rotator 4k

Guide camera and OAG 2k

I think you are just trolling; based on your previous posts here and here you currently own an 8" evolution HD, an ASI294MC camera, and an AVX mount.  You seem to be struggling calculating backfocus as well. This tells me you are just getting into this hobby ~ I could be wrong though. 

 

If you are truly a beginner and looking a spending 100k I think your making a huge mistake.  No amount of money will replace experience.  My advice is learn to use what you have and until you find all the pitfalls in your current equipment do not spend $100k.

 

Show us the money (by that I mean show us that you are really serious in spending 100k) and then we can help... until then this is just hypothetical and as CharlesW mentioned above with will simply erupt in flame wars. 

 

Just my 2 cents.

I think you are just trolling; 

Or daydreaming... why flame wars?  With 100K you can have it all!  Heck, I ran out of ideas at 67K!

I know of an individual (don't know him, but a friend did some consulting for him) who has an observatory attached to his 2.5 million dollar house in the Colorado mountains. It houses a PlaneWave scope (not sure which one) and everything else is of corresponding quality. If you want to see what it's possible to spend, go here.

I'll take one of these and have 50K left over for a frac and eyepieces:

I'd use the funds to get some land under pristine skies with good seeing. South island of Kiwiland or the Atacama in Chile. 20k left over would buy a really nice Dob and a herd of goats/sheep to keep me company. smile.gif

My in-laws have a dark site, that's why I like to visit them...  so let's assume free land.

 

Like Araguaia, I like the Planetwave!  The 0.6 Meter or 24" is $80,000  the other $20,000 would be for a roll of roof, pier and a camera.  I can build the building and pier, so that would leave me well over $10,000 for a camera.

 

It's fun to dream...

Jaimo!

I'd do some research to see where in Michigan that the seeing conditions are best.  Then I'd buy a piece of land, a small travel trailer, and some better optics.  There would be money left over so I could go out west from time to enjoy clear skies.

 

I'm 25 miles from Lake Michigan, seeing here tends to hoover.

The OP asked what equipment you would spend 100k on. This would seem to presuppose that you don't have to worry about a site or building, just the equipment. And at the individual level, that means "how would you equip an observatory". If you are a imager, the suite would likely look very different from a purely visual observers gear. So, what would you spend 100k on to equip your turn-key-ready-under-dark-skies-observatory?

 

For my part, I would immediately place an order for a TEC 250 triplet APO and an AP 1600 with absolute encoders. Why? Because I love refractors and refractor viewing and imaging...this would be my ultimate OTA and mount.  This would also leave me about 35k for accessories, mounting hardware to piggyback other scopes, cameras, eye pieces, EAA devices, NVDs, superb binoviewer, etc. Pretty sure I could scrape by on that budget smile.png

 

Clear Skies,

Bingo! To spend that kind of change and not have the most optimal observing conditions to fully realize that investment, would be in effect wasting that money.

 

So I'd spend $50K on a dark site property. Next,  I'd get something like a huge short focal length Dob like: http://www.websterte...3_Telescope.htm and use the balance for a roll off roof observatory house it.
