Prinz Optics 550 - Anybody have one?
      #4739095 - 08/09/11 04:50 PM

I've been searching the forums to see if I could find anybody with one of these scopes, but without success. Somebody on here must have one surely? I have recently acquired one of these and would be interested in hearing from other owners. I have one slight alternative motive; I need some measurements.
I found on a terrestrial first light, that this appears to be a good objective, but with very poor contrast. On removing the focuser assembly, I discovered two baffles in the tube; both reflecting huge amounts of light. If anyone has one of these, and they'd be agreeable to removing the focuser, I would like the measurements of the two baffles from each end. The reason I need this is because from marks I found, I suspect that one of these has been removed at some time, and I can't be sure if it's in the correct position. How critical these two baffle positions are, I'm not sure?
If somebody has one of these scopes and doesn't feel inlclined to remove the focuser, I don't mind in the least; I'd still be interested in opinions of this model.
Cheers
Max
p.s. pics will follow eventually.

I have a prinz astral 500, not sure what the difference between this and the 550 is, mine is Towa brand 60x 910 on an equatorial mount.

Hi Grendel!
I thought you might be along. The 550 is also 60x910 but circle K. As soon as I get it together, I'll do an album. I did do a piccy of the focuser today, which you can see at the bottom of this page:
http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/4671176/page/0/view/collapsed/sb/5/o/all/fpart/3/vc/1
The wooden tripod is the sturdiest of all the wooden tripods I have. The mount is heavy and simple; no setting circles. The finder fits in a reducing dovetail, and is pretty good, although it had been severely abused by somebody very heavy handed! If the blackening I intend to do helps the contrast to a marked degree, I suspect I will be very happy with this scope.
How does your 500 perform?

my 500 is a Towa and an excellent performer, I am starting to suspect that the Prinz scopes with *00 numbers must be Towa and with **0 numbers Kenko (circle K) like the 660 I own.

dimensions - draw tube length 205mm
baffle from eyepiece end 74.4mm
baffle from objective end 6.3mm
diameter of baffle hole 14.4mm (both baffles believed to be identical - but its a bit difficult measuring a hole diameter 74mm down a tube - a small bar inserted into the draw tube and rested inside the baffles appeared to be parallel.

I would say you definitely need to do something about that, it should improve things no end.

Hi yes I have one it was given to me as a present in about 1968, used it a lot then, even got an A level in Astronomy, now 44 years later still have it and got it out of its box tonight for the first time in over 30 years it still looks ok, thought it was not very good at the time as unless you had at least a 3 inch refractor or an 6 inch relector it wasn't a proper telescope

Hi Gordon,
Just picked your post up. I'd be very interested to see pics of your scope if possible? If you don't want to post here, PM me and I'll send you my email address. You don't give your location in your details, but if you're anywhere near me (Peterborough UK) I'd love to see your scope.
Regards
Max

Hi Gordon!
Lucky boy, yours is in far better condition than mine! Could you do me a couple of close-up piccies of just the mount please? I've still not found anybody else who has one of these scopes; so far we're the only two.

Brilliant Gordon; thanks! I not a few small differences, suggesting that your's is either earlier or later than mine. I will try and get some piccies tomorrow if I can. Look after it, it's an uncommon beast, particularly in it's box.

That Soligor sounds interesting; is it an old one? The rain is of course obligatory with a new scope!

Hi Max looks like a well made bit of kit made in Germany in about 1993 as far as I can tell these are the details
93 mm, magenta hardcoated,f/l 1000mm, f/r 1:10.3,resolving power 1.33, german mount, and hopefully a poor pic attatched

Hi Gordon,
I have to admit I don't think I've ever seen a 93mm before; a strange size. I hope it turns out to be a good'un!

Hi Max just been out looking at Jupiter and Venus and Mars, can just very faintly pick out the bands on Jupiter and seen Venus as a cresent and Mars no detail, images are a bit bigger and brighter than before max usable mag seems to be with a 10mm eyepiece ie 100X, trouble is I don't know what expect

Hi Max

Just came across this thread and was interested as I used to own a Prinz 550 scope. My parents bought it for me I believe it was Christmas 1971 or thereabouts. Prinz was an "own label" at the time for Dixons photographic shops and they used to stock a full range of mainly refractors, numbered 100,220, 330,440, 550 and 660. The 550 and 660 were better quality buildwise, with Circle K Kenko optics and very sturdy mounts.

The lower numbers had Towa optics which were also good, but made with cheaper metal (and some plastic) components.

The 500 model was a much cheaper built later model from the 1980s, again built by Towa (Circle T) but in industrial quantities and using other non traditional colours such as royal blue and grey. A real step down on the earlier scopes, in my opinion.

The 550 model was a 60mm F15. As such, it was always going to be limited in performance, at only 60mm, but it was so well built that it could deliver great views of the moon, double stars and Jupiter/Saturn etc - enough to get young lads like me hooked on stargazing!

I've seen and used early Swift scopes and the finish and performance of both the 550 and 660 (3" F16.5) scopes were right up there with those iconic scopes.

Hope you are still enjoying yours.

clear skies

Dave

Just picking up this thread once more...I've always thought that the unusual grey paintwork on these Prinz Circle K scopes is reminiscent of the Swift refractors and some Greenkats.. does anyone know if these Circle K scopes share any DNA with the Swifties? I've now got a 660 76.5mm F15 with original wooden crate and am being offered a grey 550 like the ones pictured in this thread..am very tempted!

thanks,
Dave

Would be surprised if there are no "common genes"...maybe not the optics but surely the mechanics. Or is it a case of pure imitation?
