|102mm achromatic refractor operating at f/9.8 with a focal length of
Large 102mm achromatic refractor that ships with a 25mm Plossl eyepieces, 6x30
finder, mirro diagonal, and a CG5 equatorial mount with an
no longer own this telescope, but looking back I now consider that this scope
may be one of the best buys.
Of course there was always a mild violet halo around bright objects and this
could be eliminated by using a yellow or orange filter which also would improve
contrast on planets.
The double-double was cleanly split. Cassini's division very evident. Very good
contrast on brighter deep-sky objects.
The CG5 is a copy of Vixen Polaris mount. It can be improved by removing its
glue-like lubricant and replaced with bicycle lithium grease.
I found that the Vixen controllers and motors were much superior to the
Celestron, s-Chinese made motor systems. The Vixen motors were a perfect fit.
The mount will be vastly improved by replacing the shaky aluminum legs with
I also lined the inside of the dew-cap with felt.
This telescope will accept 2 inch eyepieces and diagonals.
Easy to use, good-looking.
A true beginner's (and old-timers too) telescope.
P.S. Aries of Ukraine, through APM is marketing fluorite lenses that can
convert this telescope into an APO (about $500.00).
