Notes
|
| Criterion RV6 6" (0.15 m) Newtonian (1981) | Excellent optics. Sold (big mistake) in 1985 to build a 10" dob. |
| Stellarvue Models 1010, SV105T, SV102T, SV80, and SV70T | Excellent American made telescopes. Triplet models required field flatteners for imaging. |
| 8" f/3.9 Newtonian (2020) | Use with an Explore Scientific coma corrector on a Twilught II mount. |
| 4" (105 mm ) f/6.2 Stellarvue SV105 apochromatic refractor (2005) | Great for imaging and viewing. Excellent optics. Needs field flattener for imaging. Sold in 2006 to buy SV102T. |
| 5" (127 mm) f/10 Celestron C-5 Schmidt Cassegrain (2000 & 2020 Models) | Best SCT ever made. Sold both (had too many scopes). |
| 8" (0.20 m) f/7 Discovery Newtonian (2001) | Excellent optics, great visual views, no visible coma, excellent astrograph. Sold in 2010 for move to Hawaii. |
| 4" (102 mm) f/10 Buschnell 4000 Schmidt Cassegrain (1995) | Solar eclipse airline travel scope. Sold in 2013 to a Maui whale photographer. |
| 70 mm f/6 Stellarvue SV-70 achromatic refractor (2011) | Guidescope and wide-field spotting scope. Sold in 2014. |
| 14" (0.36 m) f/6 truss tube Newtonian (2006) | Deep sky observing, excellent 1/25 wave primary! Sold in 2020. |
