Astrophotography Diagonal Mirror

The Baader Planetarium 2" ClickLock Diagonal Mirror is built for astronomers and astrophotographers who need a reliable 90-degree light path. Its dielectrically coated mirror delivers high reflectivity with minimal light loss, producing bright, high-contrast images of celestial objects. The 112mm optical length fits standard focuser drawtubes without excessive back-focus consumption. The ClickLock clamp secures heavy eyepieces or camera adapters without marring barrels.

Upgrade from Standard Diagonals

This unit replaces basic prism or aluminum-coated diagonals that scatter light or fail to hold heavy accessories firmly. The lambda/10 surface accuracy and dielectric coating make the jump worthwhile when you demand maximum contrast for planetary detail or deep-sky imaging. The UV and IR rejection adds safety for white-light and Ha solar work, a capability most entry-level diagonals lack. If your current diagonal shows ghosting, flexure or coating degradation, this mirror restores optical performance.

Compatibility Checklist

Verify that your telescope focuser accepts a 2-inch barrel or M48 thread for direct mounting. Confirm the 112mm optical path leaves enough inward focus travel for your imaging train or eyepiece combination. Ensure your eyepieces and adapters have 2-inch barrels compatible with the ClickLock clamp. No other interface or thread adapters are included, so plan for any additional connectors your specific setup requires.

Questions about this item

Does the 112 mm optical length and 2" barrel fit my focuser?

The diagonal has a 112 mm optical path and a standard 2" barrel that slides into any 2" focuser or visual back.

How do I lock an eyepiece in the ClickLock clamp without marring the barrel?

Insert the eyepiece, then turn the knurled ring about 90 degrees until it clicks; the internal brass collet grips evenly without set screws.

Will the dielectric coating degrade and need recoating?

The dielectric layer is hardened and scratch-resistant; it does not require recoating under normal use.
