Just in case you, like me, hadn't heard this: Stellarvue is offering a new 100mm f/5.8 quad for $3800. Looks like an attempt to directly compete with the NP 101. And you can get it on a Paramount MX for only $14, 495. . .

That 100mm quad must weigh a whole lot to need a Paramount MX...

That's a fair chunk of change as well, how much in a new NP101?DA.

The Stellarvue website also recommends the sub-$2000 Celestron mounts if your budget is tighter. ;) But if I were really Sirius about imaging, and just plopped down nearly four grand on my ota, I'd get the Paramount.

If I had a Paramount and I was Sirius about imaging I would not have a Stellarvue.

Since the mount is at least 70% of the imaging equation I'd be happy to have the SV Quad or a lesser scope riding on it. :jump:

I meant to put a "joking" face on there. ;) I hope this turns out to be an excellent scope for astrophotos, it definitely has a great focuser, Feathertouch 3". It's certainly not as pricey as the FSQ or NP101. (Actually the NP101 is pretty close at 3995).

I noticed this scope a few days ago when I was comparing 80's in response to something else, elsewhere.

Whoever and whatever it is made from I could care less, bought my 85 not knowing (and to some extent my 160ed) so maybe I'm just more proof in the pudding rather than the conjecture crowd? I wish it was a bit 'faster' but still for the price what else is out there?

I'd love to see some images from it using at least an 8300 sized chip. Could be a formidable competitor for us imaging folks. Would be even more interesting if a tailored reducer/flattener were to accompany it, somthing taking us into the high f/3's or low f/4's?

One vendor has the NP-101is priced at $3879 and the NP-101
for $3749.

Bweerk over here the NP101 is 4098 euro's which is over 5000 dollars.
I do like the Stellarvue offering, there is nothing wrong with more wide & flat field scopes.

There's this one for $3500 including internal flattener plus a reducer to F/5.8. They are even willing to reveal the country of manufacture (Japan).

:lol:

Vic has worked with at least one highly qualified imager (Jon Talbot) during the design phase of this new scope. You can find some images here.

You can see images and get the specs on Stellarvue's web page here. (See the links under the photo of the SVQ100 on its Paramount.) It doesn't appear that Vic will design a reducer or flattener: judging from those pictures, why mess with perfection? :ubetcha:

David, Thanks for the link - those look very NICE! The 3" FT focuser... wish my Tak had one ;) That IMO an additional HUGE selling point. Rings + case too :)

John, interesting f/8 scope to ~f/6 with reducer (which is incredibly reasonably priced!) sort of... slow?.

I currently own the SV80 triplet. I wonder if this scope would be a worthwhile step-up for me. I love my little grab n go scope and having an extra 20mm aperture in the same compact size is tempting. Mine has a focal length of 480mm and this one is 580mm, so I can use my existing eyepieces and not have the magnification change too much. I currently use a Canon EOS 5D for AP and I like the idea of no vignetting and no field flattener required. Thoughts?

It's made by Sharpstar Optics in China,who also makes SV50ED,AT65Q,APM107PH and so on.The SVQ100 looks like a larger version of AT65Q.Here's a test report of the prototype on an astronomy forum in China:

Very Nice test from what i can read :-) looks like stellarvue have designed a winner here by coupling nice optics with I feathertouch ;-)

Yes, and it didn't escape my notice that a scope almost identical to my SVR90T appears on the Sharpstar website...

If you're talking about this scope, the focal length is different (630mm for the SV 90mm f/7 triplet vs. 600mm for the Sharpstar 90mm f/6.67 triplet). But you're right--the CF tubes do look pretty similar.

I'd be interested to see the actual focal lengths measured...I suspect they are the same 90 mm lens assemblies as well. Regardless, my 90 is a great scope.

Alan, I guess they could be. But > 1 inch difference in FL is quite a large "fudge factor" if the lenses are truly the same. I dunno. :shrug:

The focal length spec for even the very high-end LOMO 80mm triplets is +-5%. Either of those figures is within that span of the other so in that context they are the same number (and these optics may well have a wider spec than the LOMO).

Interesting info, John. I had forgotten that the tolerances were +/- that much.
