About halfway into the star party Yuri and a collegue set up the 10 inch Tec for its public debut. I only had a chance to see Sirius and it's Lil pup. The white dwarf star was easily seen in the steady air and the diffraction patterns of Sirius were textbook. There was also no false color that I could see. The star test to me appeared very good. Clearly this is a fantastic optic. I'm sorry I didn't have a chance to see Jupiter as it was closed down early that night. Maybe someone can chime in on how Jupiter looked from Friday night...

Thanks Darren.  Wish I could have been there. 

 

Sergio commented on Jupiter here

 

"Being that I got lucky and Yuri set up the 250 next to my scope, I was able to get a few peeks through the MONSTER refractor. Jupiter was like a photo in a book. It had color (the good kind, on the planet itself) and overall excellent detail. Festoons galore!!! M42 and other deep sky objects were bright and contrasty. The mount was also really impressive a 10 Micron GM3000."

Thanks for posting the pix Darren.  What an incredible setup.  I hope they had a Tele Vue ep in there when Uncle Al looked through it.

And it's useable in full sunlight!  Beautiful blending of engineering and art.

Is that "I think I am going to pass out and I need something to hold onto safety wheel" at the eyepiece end for the views or the price?

Looking closely at those images, is the main tube in 3 sections?

Not really. Scope is $49000, base mount lists for $17,215. The tripod is made by Yuri but let's say $5000. Total with accessoris and all should be about $75,000. A bargain grin.gif

Do you have any specs on the scope? Focal length? Type of glass? Triplet/doublet? Air spaced/oiled? etc.

It is an air spaced triplet.

Then you need to add in the cost of the home observatory to put it in.  I think it's a mandatory accessory for this scope.

700X on a double star of 0.7" separation showed a clean, dark-sky split.  No 'hair', 'fuzz' or anything other than the central spot and the first diffraction ring.  Textbook diffraction pattern.   Identical to the views of similarly separated pairs in the steady, steady skies of the Winter Star Party last year in my 12.5" f/6.5  Lockwood/Teeter dob for a wee bit more than 1/10 the price.
