Stars for Your Buck 85/100

Recommended 25 Sep 2026 Updated 25 Sep 2026

Rank: #8 of 46 accessories
Verdict: Damon's pick

Written by Damon Scotting 2 min read

Buy it if

You guide a longer focal length refractor and want a finer guiding scale than a 30 or 50 mm guide scope gives
Your mount has payload to spare for a 790 g guide scope

Skip it if

Your mount is close to its payload limit: a 30 mm mini guide scope weighs 342 g
You want the smallest rig for travel

For a 60 mm guide scope I point to the SVBONY SV106 60 mm: 240 mm of focal length at f/4 with a helical focuser, 790 g by SVBONY's figure, with two rings and a dovetail bar in the box.

85/100 Stars for Your Buck

Pros

240 mm at f/4: about 3.2 arcseconds per pixel with the ZWO ASI120MM Mini's 3.75 micron pixels
A helical focuser with 8 mm of travel and a 30 mm telescoping drawtube
Two guide scope rings and a 3.5 inch dovetail bar in the box
A fully multi-coated 60 mm lens

Cons

790 g is more than twice the 342 g of a 30 mm mini guide scope
270 mm long, so it overhangs a small refractor
The AliExpress listing I link to opens on the 50 mm SV106: pick the 60 mm option

For a 60 mm guide scope, the SVBONY SV106 is the one I point to.
