When should I choose the Baader Mirror Diagonal over a prism diagonal?
A mirror diagonal, like this one, is generally preferred for deep-sky observing with any telescope, especially those with focal ratios of f/7 or slower. It provides excellent light transmission across all wavelengths. A prism diagonal can sometimes be a better choice for high-magnification planetary viewing in refractors, as it introduces no scattered light, but it may not perform as well at very fast focal ratios.
How does the Baader 2" ClickLock Diagonal handle heavy eyepieces on my Celestron 8" SCT?
The Baader ClickLock diagonal is an excellent match for a Schmidt-Cassegrain Telescope (SCT). Its secure, three-point grip is specifically designed to hold heavy 2" eyepieces, such as wide-field Naglers or Panoptics, without any wobble or tilt. This ensures that the collimation and alignment of your SCT's optical path are maintained perfectly.
Will the ClickLock mechanism scratch my eyepiece barrels?
No. In fact, the ClickLock system is designed to prevent the very scratches and gouges that traditional thumbscrews cause. It applies firm, even pressure using hardened rollers against a compression ring, never making direct metal-on-metal contact with a sharp point.
Is the Baader 2" ClickLock Diagonal compatible with both refractors and SCTs?
Yes. This diagonal comes with a standard 2" nosepiece that fits into any 2" focuser, common on most refractors. For use with an SCT, you will need an SCT-to-2" adapter that threads onto the rear cell of your telescope, which then allows you to insert the diagonal.
What is the advantage of the Baader ClickLock Diagonal in cold weather?
The large, knurled locking ring is easy to grip and operate even when wearing thick winter gloves. This is a major advantage over tiny thumbscrews, which can be difficult or impossible to turn with cold hands or gloves, making eyepiece changes much faster and more comfortable during winter observing sessions.
How do I clean the mirror on my Baader ClickLock Diagonal?
The mirror should only be cleaned when absolutely necessary. First, use a bulb blower to remove any loose dust. For fingerprints or stubborn residue, use a dedicated optical cleaning solution and sterile cotton balls or optical wipes. Apply the solution to the cotton, not directly to the mirror, and gently wipe in a single direction. Avoid excessive pressure or circular scrubbing motions.
