Review: Stellarvue SV102ED

Four-inch refractors engross the astronomic sweetly mark for yard Galileos: boastfully plenty to prepare expectant detail, size plenty to set up on simple, non-motorized mounts. The SV102ED2 uses low-dispersion glass in its two-element lens to minimize color aberrations that can cause annoying halos around luminous objects. Views are bright and crisp, with plenty of detail.

Stellarvue SV102ED

7/10

Wired

Every unit is personally inspected and tested by either company founder Vic Maris or his senior technician. If you want to save a few hundred bucks, you can skip the two-speed focuser — Stellarvue's standard unit is also very smooth.

Tired

Lens shield snags when extended or retracted. Logo is a slapped-on decal instead of being painted on — petty gripe, but it diminishes an otherwise marvelous rig.
