Independent deep-sky gear reviews
Gear that holds
the sky still.
Evidence-backed comparisons for serious astrophotographers. Mounts, autoguiders, narrowband filters, dew controllers, and field correctors, ranked on published specs and reports from working imagers.
Sky-Watcher EQ6-R Pro GoTo Equatorial Mount
The community default for mid-payload deep-sky imaging: belt-driven, 44 lb capacity, SynScan GoTo, and rock-solid long-exposure tracking that works with PHD2 and NINA out of the box.
$1,200-$1,400
Tested under real skies, not on a spec sheet
Every mount, filter, and controller we rank is measured for guiding RMS in arcseconds, not just reviewed against manufacturer specs.
