What is the primary purpose of the Baader 3.5" Quick Changer for PlaneWave?
Its primary purpose is to allow for the secure mounting, precise rotation, and rapid exchange of heavy instrument packages on large PlaneWave CDK telescopes. It addresses the mechanical challenges of handling large-format cameras, spectrographs, and other heavy visual or imaging accessories without introducing flexure or losing collimation.
Which specific telescopes is the Baader Instrument Rotator compatible with?
This rotator is designed specifically for PlaneWave CDK 14", 17", 20", and 24" telescopes that are equipped with the 3.5" Hedrick Focuser. It is not a universal rotator and is engineered for the mechanical and optical requirements of this specific telescope series.
How does the Baader 3.5" Rotator help when imaging with a PlaneWave CDK17 and a large format camera?
With a PlaneWave CDK17 and a heavy camera, achieving perfect framing is essential. The rotator allows you to precisely orient your camera to compose your shot of objects like the Andromeda Galaxy (M31) or the Veil Nebula (NGC 6960) without having to physically rotate the entire telescope tube or risk loosening threaded connections. The quick-change capability also means you can remove the entire imaging train as a single block for storage or maintenance and re-attach it with perfect alignment.
I want to switch between a spectrograph and a visual setup on my CDK20. Is the Quick Changer suitable?
Yes, this is an ideal application. The Baader Quick Changer allows you to pre-configure two separate instrument packages—one with your spectrograph and another with a 2" diagonal and eyepieces. You can then swap between these entire setups quickly and securely in the field, knowing that the mechanical connection will be rigid and repeatable each time.
What does "adapts to M68 and 2-inch systems" mean?
This means the output side of the rotator is designed to connect to accessories that use the Baader M68x1 thread system, a common standard for large-format correctors and accessories. It also allows for connection to standard 2-inch accessories, like diagonals or camera nosepieces, via appropriate adapters, ensuring broad compatibility with your existing equipment.
Is the Baader 3.5" Quick Changer difficult to install?
Installation is straightforward for users familiar with the PlaneWave Hedrick focuser. It threads directly onto the focuser's 3.5" collar. The primary consideration is ensuring your entire imaging train remains within the back-focus requirements of your specific optical configuration, which is a standard part of setting up any imaging system on a CDK.
