*Updated 5/18/2024Yes, it is still available.  I will pull the ad the moment it payment is received.  I feel like I priced it correctly, based off condition and other ED102 sales.  But then again, I was wrong one time, back in October 1983 ... so ya never know.  Please feel free to make a serious offer (above) or below asking price and it will be considered.

ES ED102mm Apo 

This ad is for a well-cared for excellent condition ES ED 102mm APO triplet - The Explore Scientific (ES) Extra-low Dispersion (ED) 102mm (4”) Essential Series Air-Spaced Triplet Apochromatic (APO) refractor telescope, to be technical.  These APO’s use Hoya extra-low dispersion glass FCD1 glass with EMD coatings and live up to their popular reputation. 

This has been my visual grab and go scope for a few years and it never disappoints.  Bright, clean, crisp, unobstructed views as you’d expect from an Apo. I’ve had it consistently mounted on an ES Twilight AltAz mount ready to take out to the patio whenever the seeing allows.  The scope and its optics are in perfect working order.  Please thoroughly look over the pics, the ad only allows eight but I have plenty available.  The scope is in excellent condition.

The sale includes;

  • OTA – Triplet Air-Spaced APO 102mm refractor, f7, 714mm
  • 2-speed rack and pinion Focuser
  • 2-Extension tubes as shown
  • Cradle (rings) vixen

(Finder, diagonal, tripod, and eyepieces are not included.)

Asking $725 (New costs $1,199 for the same views)  Paypal, Venmo, or cash only.

I’ll ship it UPS or FedEx (no USPS) from Spring, TX 77386 to CONUS.  Or will deliver halfway, up to 100 miles from Spring, TX.  The scope weighs about 13 pounds without packaging.  I have the original box/packaging, but may be missing a few original foam pieces.  I will package securely.  I have no idea what shipping will cost, but I will carefully and thoroughly protect/secure it.  Buyer pays shipping, I’ll pay for the shipping insurance cost.  We can finalize shipping once it's boxed up. 

Happy to answer any questions, thanks for looking!
