Sorry, 6 inch f7.0  The camera site is in error.

 

Editor’s note: The original story stated a 1050mm f/5 lens, which is incorrect. It is a f/7 lens. We apologize for this error.

It’s a 6” (150mm) refractor.

Kind of some weird processing in some of those sample images. I'm guessing it must livestack- long exposure on an alt-az at that focal length, even with a really forgiving image scale isn't super conducive to long exposures. I'd read more about it....but this new fad of super easy to use "automated" telescope packages with pretty typical hardware and astronomical price tags isn't for me. Thumbs up to those who buy em though.

I don't understand how it can produce such images. A couple look like the Hubble Palette which would need different filters?

Has mono sensor and probably filter wheel.

Honestly if money were no object I would own it. I also would own those fancy wavy lounge chairs for my penthouse astro deck. 

 

This could be useful for science museums/centers outside of people with lots of cash.

It’s a 6” (150mm) refractor.

I see "massive 1050 mm lens", which makes over 41 inches.

Focal length 1050mm, aperture diameter 150mm, focal ratio f/7. Seems like it could be a COTS objective.

I betcha that is the focal length, similar to how camera lenses are described.

From their website:

 

150mm Apochromatic (Triplet) refractor.

Focal length 1050mm (F/D=7).
Field of view: 1.97° x 1.3° (F/D=7).
Limit magnitude: 20.
Theoretical separating power: 0.9arcsec.
Sampling: 0.7arcsec.

Just to add, I suspect that this may be some kind of Petzval, if not, then it's one of the fastest apos I've seen for that aperture.  I was quoted double that price for an f4 8 inch so the price seems to be in-line.

And it derotates? 

 

Can it be left permanently outside?

$52,000 for a 6" triplet (more likely of chinese origin) is quite a steep price.

 

 

Let's break it into components (without cutting corners):

 

• 6" f/7 Skywatcher Esprit (with flattener) $6,700
• ASI 6200MM camera +7 filters & wheel + guiding camera and OAG $5,500

• ZWO EAF $200
• ASIAIR Plus for remote control with telephone/tablet $300
• CEM70 equatorial mount + tripod $3,500

 

Grand total : $16,200

 

I may have forgot few things like a battery but you get the idea wink.gif

The description says it’s an f/5. That would make it a 210mm objective.

Another toy for the super rich who know nothing about science?

I have seen how some wealthy people spend their money, and it's enough to make one laugh.

Maybe Neiman Marcus will have his and her $50,000 telescopes for Christmas.

Personally I don't have a problem with this sort of thing. I'm sure this would be pretty nice for someone who can afford it. I find these all in one imaging setups appealing. I am someone who has zero interest in learning how to do imaging or even EAA. So one of these is something I would be willing to try. However, I will stick with the $1500 one if I do get one.

Why even include a lens or camera? Put a $19.00, piece of glass on the front of the tube, download a library of digital Hubble pics onto a hard drive in the tube. Have the tube point towards the sky where one of the several thousand Hubble images on the hard drive come from and just display the image. It will even work when it’s cloudy. If there’s no eyepiece, no one would no any different.

There's a mistake in the petapixel article, see below:

Petapixel is a second-rate site, I just saw the thing there.  But I had a feeling that company wouldn't be able to sell an 8 inch with a camera for that little money.  They probably charge at least 4 times the cost of the thing, like their other scopes.

For 50,000US$ you can get a dream APO or gigantic reflector…..I watched through an almost 1mt diameter Dobson lens one year ago and I could see the Veil Nebula so contrasted and detailed that I seemed floating into space…

Yes, I saw Stephan's Quintet through a 40 inch Dob that probably cost 1/2 that build.  Different scopes...
