Takahashi Mewlon 210 for sale. Unit comes with Tak 7 x 50 finder, Takahashi dovetail saddle plate, ScopeGaurd case, Bob's knobs (not installed). All in very good condition, except dovetail saddle, which shows some normal wear. Displays excellent contrast and resolution. Selling because I purchased a CN-212, so this beautiful instrument needs to find a new home.
This quote is taken from the Mewlon 210 review in the Practical Astronomer magazine: “Extremely well corrected and smooth optical surfaces. Well engineered with thoughtful design. …the popular SCTs do not even come close to matching this instrument’s optical and mechanical quality.”
Photos shown were taken with this OTA by it's previous owner, I have not done any astrophotography with this scope myself.
