Welcome to Chicagoland Astro-Ads! This page is provided as a free service to amateur astronomers in the greater Chicago, Illinois area as a place to post astronomy related classified ads, and to shop for used astronomy equipment within a reasonable radius, enabling buyers to personally connect with the sellers. Your hosts are the Naperville Astronomical Association, one of Chicagoland's many fine amateur astronomy clubs. To submit an ad, see the information at the bottom of this page.

--A word of caution to users of this page: The Internet is prowled by crooks, too. If your ad is posted here, you may get responses from various scam artists as well as serious purchasers. And while we've never had any complaints about scam postings, we cannot guarantee the honesty of the people posting ads here, either. Again, the purpose of this service is to help local astronomers connect; we suggest that you complete your transactions face-to-face! (To you crooks, go looking elsewhere for victims; this page is for local U.S. sales, and the sellers here aren't going to ship overseas!)--

  • 20" Obsession Classic F/5 Telescope
    Asking price: $4500
    Description: I live in McHenry, IL - close to the Wisconsin border- and am a member of the Milwaukee Astronomical Society ( MAS ). I am selling my 20" Obsession Classic F/5 Telescope. It is in very good condition and I am the second owner. This particular telescope has 2 features you cannot get any longer - a mirror done by John Hudek of Galaxy Optics (according to their website they are only re-coating mirrors now and genuine ebony star formica on the altitude bearings (its no longer being made -the current "ebony star" is not anywhere near the same texture).
    Mirrors by Galaxy Optics were one of the most sought after brands of primary mirrors and this one is a great example: "Here's the test data for SN01842: PV = 0.235 RMS = 0.036 Astigmatism = 0.197 Strehl Ratio = 0.950 The mirror is excellent."
    Scope includes custom shroud, dual speed JMI 2"/1.25 focuser, telrad finder. I am going to put it up on eBay for 5000.00 but will offer for local parties for 4500.00 cash ( paypal is fine too but we will need to at least split the fees) as I would prefer not to ship the scope.
    Please feel free to respond with any questions or if you'd like pictures.

    Orion XT10i Dobsonian Reflector with Intelliscope Controller
    Asking price: $700
    Description: This was my first dob and I loved it, but I bought a bigger one and this one sits unused night after night. The 10" dobsonian is the largest dob that can fit across a back seat of a car without needing a truss tube design. I had this at our dark sites many times, and at 10" it's large enough to see a lot of objects in the night sky. The XT10i (retail $849) comes with a Telrad finder (retail $40), Bob's knobs (retail $21), a Padded Telescope Case (retail $121) and a custom cooling fan, and I flocked the tube around the primary and secondary mirrors. There also is a removable eyepiece tray on the base that will hold 4 x 2" eyepieces. I only tried using the Intelliscope DSC a few times, and it was before I knew a lot of stars so it would almost always timeout before I could complete an alignment, but I became pretty good at star hopping because of this scope. I'd personally say it's an excellent scope for a beginner, intermediate, or an expert that doesn't want the hassle of lugging out a giant scope. If you are board when waiting on your astro imaging to finish it's exposure this dob will be your best friend. I did drop the lens cover about 3 days after I bought it, so it has 2 external chips that don't impact the view, but it's worth noting.
