iOptron Alt-azimuth Adjustable Base 80mm Vixen saddle -30 to 65 deg latitude +/-5 deg azimuth

SKU CH-DSNJ-RT6V9

Adjustable alt-azimuth base with 80 mm Vixen saddle, -30 to 65 deg latitude and ±5 deg azimuth for precise polar alignment

  • Robust 80 mm base minimises vibration for steadier views
  • Vixen dovetail saddle accepts a wide range of telescopes and cameras
  • Latitude adjustment from -30 to 65 degrees enables accurate polar alignment
  • Azimuth fine-tuning of +/-5 degrees allows precise tracking alignment
  • Built-in bubble level ensures quick, accurate horizontal levelling

azimuth Base for SkyTracker and SkyGuider

The iOptron Alt-azimuth Adjustable Base attaches to SkyTracker Pro and SkyGuider Pro mounts as well as other small camera mounts. It provides a stable 80mm diameter platform with a Vixen-type dovetail saddle for telescopes and optical instruments. The base is built for astronomers and photographers who need precise polar alignment during imaging sessions.

Installation uses standard tripod threads

Mount the base to your tripod using the existing mount hardware then secure the optical tube in the Vixen saddle. A built-in bubble level helps you level the platform quickly before adjusting altitude and azimuth. The main difficulty is achieving fine polar alignment when the mount is already loaded, so adjust latitude and azimuth gradually while watching the polar scope or alignment routine.

Verify your mount accepts the base

Confirm your tripod head or mount has the correct threading to accept this base before ordering. Ensure your observing latitude falls between -30 and 65 degrees so the altitude adjustment can reach the celestial pole. Check that your optical tube uses a Vixen-compatible dovetail bar and that the total payload does not exceed the capacity of the underlying mount.

Questions about this item

How can I verify the base is level after mounting it on my tripod?

Use the built-in bubble level on the base; centre the bubble to confirm the 80 mm mounting platform is perfectly horizontal before attaching your instrument.

What comes with the adjustable base and what must I supply separately?

The base itself includes the Vixen-type dovetail saddle and integrated bubble level; you must provide a tripod, a Vixen-format dovetail bar for your telescope or camera, and any mounting hardware for the tripod head.

Which latitude range should I set on the base for my observing site?

Adjust the latitude scale between -30 and 65 degrees to match your site latitude; the +/-5 degree azimuth fine-tuning then lets you dial in precise polar alignment.
