Description:
1) Celestron EQ fork mounted tripod and mount, circa 1986, for C-11 telescope.Very sturdy and stable system ($638 new)
2) Revolving plate from Howard Engineering allows 360° rotating of OTA..very convenient addition (~$150 new)
3) Celestron 10x20 spotting scope and mounting bracket (~$80 new)


All components in mint condition stored in padded containers. Original invoice prices in parentheses. Original invoice available to verify. Suggested selling price is very negotiable and open to discussion. I live in Darien Illinois.

I recently converted my C11 to a go-to system, hence the reason for selling. I recently joined the NAA so as to learn how to maximize the inherent capability this go-to system provides. Sale of this will allow me to add other accessories to my upgraded Go-To telescope. Plus my wife told me that I need to make room in the house.

Thank You for looking.

Description:
Let the GPS satellite system help you align your telescope. Works with any Celestron mount, also Skywatcher, Orion, etc. Don't guess at your position! This unit will input your data as to latitude, longitude, and altitude to within a few feet accuracy. I have used this system on my Celestron 14 inch SCT, a Meade 10 inch SCT, and my current Skywatcher 150mm triplet refractor. Works great.

Description:
Less than a year old AT102ED for sale in Naperville. I want to love the scope, but it just doesn't fit my observing style. Original boxes, excellent condition except for a couple of dimples in the Vixen rail from my mount screw. Full description and specs can be found on the astronomics.com site. Depending on specifics, I'd consider a trade or trade plus cash for a faster refractor in the 70-90mm range.

Email me for pics if you're interested. Prefer local sale due to probable high shipping costs, but I'm somewhat flexible. Cash or PayPal only please.
 
Skywatcher ED 120 refractor
Asking Price: $450

Street Address: 2490 GOLF RIDGE CIR
City: NAPERVILLE
State: IL
Posted: Aug 24, 2021
Updated: Jul 13, 2022
Description:
Scope was bought used from Cloudy nights Classifieds. OTA (and case) only with lens covers and 2" diagonal with 1-1/4" adapter. Has a finder base but no finder. Also a 1.25" 5mm Skywatcher 1.25" eyepiece and 20mm eyepiece, which I have not used. Glass is very clean. Not-so-good items: 1) focuser is stiff and may need attention. Telescope case looks good but appears to start coming apart if picking up by the handles. Cradling the scope case works and it works fine for storage. Need to clear out some space and this is somewhat large and bulky.

Hyperstar for Celestron C11-HD

Updated: Nov 1, 2023
Description:
I used the Hyperstar a few times, then got an astronomy camera so no longer use the Hyperstar. It's in excellent condition.
These are $999 new from Starizona.
It comes with a Nikon adapter (you can purchase a Canon one from Starizona) and an adapter for an SBIG 8300 camera.

For an extra $10 I'll throw in a Bhatinov mask made for use with the Hyperstar (it opens in the middle so you can put it on the C11 when the Hyperstar is on).
