iOptron Camera Adaptor 1.25

This adaptor connects a C-mount camera to the iOptron iE5100 Planetarium Imager. It fits 1.25 inch focusers or visual backs for direct telescope attachment. The metal construction provides a stable platform for astrophotography.

Replaces improvised C-mount connections

The UNC 1"-32 male thread eliminates wobble that can blur long-exposure images. Upgrade when your current setup lacks a secure, precision-machined interface for the iE5100 imager. The rigid metal body maintains alignment throughout extended imaging sessions.

Suits astrophotographers using C-mount cameras

Users with non-C-mount cameras or different thread standards cannot use this adaptor. Builders needing larger focuser diameters or alternative mounting systems should look elsewhere.

Questions about this item

Will the 1.25" barrel fit my focuser or visual back?

The adaptor has a 1.25" barrel designed for standard 1.25" focusers and visual backs, matching the iE5100 imager specification.

How do I attach my C-mount camera to the adaptor without cross-threading the UNC 1"-32 thread?

Align the camera's C-mount male thread squarely, turn gently by hand until fully seated, then lock the adaptor into the 1.25" focuser before tightening any set screws.

Does the metal construction require any lubrication or corrosion protection over time?

The all-metal body needs no lubrication; wipe threads clean after each session and store dry to prevent oxidation on the UNC 1"-32 and 1.25" surfaces.
