This is the place to buy, sell, and trade all your astronomy stuff …

Disclaimer: In the interest of avoiding copyright issues, allow me to point out how this part of our website has absolutely nothing to do with the Ferengi bartender on Star Trek: Deep Space 9. Really. Granted, Quark was a wheeler-dealer and knew how to get what he wanted, but that’s about the only similarity. We named this page “Quarks Place” (sans apostrophe) simply because quarks are the fundamental building-blocks of matter (at least according to the current Standard Model). And the hardware available here is just that — the building blocks of an astronomy machine. Cash or equal value can be considered the gluons via which these quarks interact. Your latinum is no good here.

For sale: Meade 10” LX200 classic telescope with the tripod, 120v AC and 12v DC power converters with 25’ power cords, dew shield, 8x50 finder scope, electric focuser, piggy back bracket, and soft sided carrying case. The telescope is in very good condition. I have had the scope for about about 14 or 15 years, haven’t used it for 7 or 8 years. I’m also including a set of Meade ccd color filters, Meade ccd 3.3 focal reducer and ccd variable T-adapter, plus some other equipment. I’m asking $ 1,800.

I am also selling a Pier Tech electric telescoping pier with a Lati-wedge made for the latitude of Sierra Vista. All the hardware, bolts, nuts, washers and plates are with the pier. Pier Tech can make new legs for it to make it correct for anywhere in the world. The pier and wedge have never been used and the only time the pier was out of the box was to take the photos. New today, the pier and wedge are $3,400. I’m asking $2,800.

All the prices are negotiable. All the equipment is in Sierra Vista, AZ. No shipping.

For Sale: Celestron Skyris 618C Color CCD Camera

Celestron Skyris 618C color CCD camera

2-meter long shielded USB cable
Driver CD including iCap software and Registax Software
1.25” adapter
Ferrite chokes (two)

For technical specs on the camera, check this URL:

Excellent camera for planetary imaging and high speed imaging. (I have used it for speckle interferometry running shutter speeds as low as 4 milliseconds per frame.) Recent acquisition of a faster monochrome camera for speckle lets me part with the Skyris.

Cable was shielded to help reduce noise from an AM radio station 1 mile from my observatory.

In April of 1992 I bought a dobsonian telescope with a 17.5" mirror from Coulter Optical. They are no longer in business. I paid $1239.13 for the telescope. (Tax incl.) I have enjoyed using it but no longer have the means to transport it to a dark sky. The telescope needs to be used by someone who can get full use out of it so I am ready to bid farewell. I have just the original eyepiece that came with it. I never bought any extra eyepieces or filters. The overall condition of the telescope is good, but the mirror has never been cleaned.

Selling my 14.5" f5.2 Dobsonian with 2" diagonal, asking $2200, need to sell because it has become too much for me to handle. I am the original owner and built it from an AstroSystems TeleKit in 2000. The mirror is by the late Pierre Schwaar. Scope has been well maintained and comes with comes with equatorial platform and XP4 Sky Commander.

This sale includes Telrad, filter slide with UHC and OIII filters, transport box for mirror, shroud, scope coat and other goodies too numerous to mention.

This sale DOES NOT include eyepieces, so you'll need to supply your own.

Will NOT ship but am willing to meet approximately half-way. I live in Phoenix, AZ.

I plan on having it at the 2015 All Arizona Messer Marathon for those interested.

For sale: one Celestron 12 mm orthoscopic eyepiece. 1.25" diameter, fully coated, with protective caps, excellent condition. Experience that high-contrast ortho view with only 4 lens elements between you and your target. A real bargain at $30 (about half price).

For sale: Coulter Odyssey II Dob, 17.5" aperture, 2000 mm FL, f.4.5 primary, 2" secondary and 2"/1.25" helical focuser, Meade 9x60 RA finder, home-made off-axis aperture stop for 4" and 6" (which also serves as a lid), and a home-made caster-based platform for ease in moving it around on hard surfaces. Of course it has the original alt-az base, and still moves easily on both axes. It has the classic orange sonotube housing. Collimation is pretty good right now, but I don't own a laser collimator, and it could probably be tweaked a bit. Brand new (1985) it sold for $1195.

It would come with only a single eyepiece: a 2" 50 mm Kelner (manufacturer unknown) that provides a 45-50 degree AFV at 28x, great for extended objects like M31, the Double Cluster, and M81-82.

Now the downside ... the orange vinyl coating is scratched in several places from years of transport, not terribly, but it looks worn in a few spots. No dents. Also, it's still the original 8th-wave mirror, which was awesome in its prime, but needs a re-silvering. The secondary appears in fine shape. Deep sky objects are still great, albeit with slight loss of contrast. Planetary and lunar show some loss of resolution due to the mirror's condition. But still, not bad when using the aperture stops. The mirror is NOT scratched, but suffered from years of storage in Phoenix where condensation of "acid smog" caused etching of the silvering. The mirror was removed and cleaned twice, following recommended procedures. I understand that re-silvering can run a couple hundred for a 17.5" (plus shipping).

Price: $500 firm.
