Meade Model 226 60mm Refractor


Shown above is a newly acquired, old, Meade model 226, 60mm alt-az refractor. I had to replace seven missing screws of one kind or another. When acquired, the scope was in its mount backwards. That situation was remedied prior to taking these photos. The prism diagonal had to be removed for a proper cleaning. Somewhat surprisingly, all optical surfaces were totally without visible scratches!

This fixer-upper scope will be used partially for educational purposes (how to make the most of the least, etc.) and partially for me to take notes and make sketches regarding what can be seen with such a telescope.


Note the stopped-down aperture of the finder: The purpose of a stopped-down aperture is to mask aberrations (distortions) that would otherwise be visible when looking through a telescope that has a poorly designed objective. Such finders can be useful under daytime and twilight conditions, but used under a dark sky for anything other than the brightest of targets they can become liabilities. I found it easier to see poorly illuminated terrestrial objects with the naked eye than with this finder! If your child's telescope has a finder like this I would suggest replacing it with something more useful such as one of the many 1x red-dot finders (or a 5x24 finder that is not stopped down) that are available now.

I'll keep the original finder on this scope for educational purposes and for those occasions when it remains of some use. An experienced observer would have little difficulty in sighting along the primary scope's tube to successfully point it as long as the telescope's magnification isn't too high, but a child might easily become frustrated without a more useful finder.

The telescope's objective is clean and scratch free, though when the scope was first acquired the objective was filthy!

At some future date, when weather and time permit, I hope to re-paint the telescope, re-finish the wood tripod legs and make some final tweaks to enhance the scope's usefullness.

I too acquired Meade model226 60 mm Refractor. It was given to me as a house warming gift to a new apartment in the city of Philadelphia which has a roof top patio. I believe that it was purchased at a tag sale in, great find in my eyes!! My refractor also had to be extensively cleaned, but no scratches on the lenses.
