The unit for sale is a Lunt LS80 DSII in great condition. There are no scuffs or scratches on the scope, and the optics are clean and in perfect condition. It was originally purchased in July 2015 from OPT.

The following components are included:
  • LS80THa Hydrogen Alpha Telescope
  • DSII (Double Stack)
  • B1800 Blocking Filter
  • Feather Touch Focuser
  • HRG: High Resolution Glass (from Lunt, $180). This optional piece goes between the etalons and greatly reduces the glare that sometimes occurs when etalons are double stacked.
  • Scope Case
  • Tele Vue Sol Searcher
  • Vixen Dovetail Plate
  • Lunt Zoom Eyepiece
You may notice that the "sweet spot" for the tuned image (i.e., the part of the field of view with the best filtering/most detail visible) is slightly off center (~1/4 degree). I asked Lunt about this, and they said that is not unusual, it is within their specifications, and it doesn't affect the image - it's just a normal aspect of the manufacturing tolerances for these telescopes. You'll likely never notice this unless you're using binoviewers, in which case, if you're like me, you'll simply want to rotate the binoviewers so that the sun is on the vertical centerline, thereby making it more comfortable to scan the sun with both eyes. The scope provides great views - I'm selling it to finance another telescope project.

The cost new of this setup is $5,975. I'm asking $4100 for the package, plus shipping (~$50 to $100 depending on your location in the U.S.) and 3% PayPal fees.

Please contact me with any questions.
