New, old refractor!Posted By Kurt Johnston |
Goggle Unitron History Project. Just about all you ever wanted to know about Unitron is on that site.Originally Posted by William GreenI'm late to the party here, I know, but I have some questions: <br><br>What is the current market price for a Unitron 4" optical tube in mint condition? (When I was a kid, I really wanted one!) Unitron 5" optical tube? <br><br>What is the level of color correction? (I assume they're just good, long-focus achromats.) How do they compare to the D & G's of today? <br><br>How consistently good (or bad) are the optics? <br><br>Where can I learn more about Unitron refractors?<br><br>Thank you.<br><br>Bill
To the original poster, congrats on the Unitron 152. I have a 1953-54 Unitron 152. The mounts are amazing considering their age. The Astonomy Shoppe website sells a RA motor with a hand controller that is battery powered and works like a charm.
