What are the three ports on the Baader FlipMirror II for?
The Baader FlipMirror II provides three connection points to manage your equipment efficiently:
-
Rear Port (Straight-Through): This is the primary position for your main imaging camera or a spectrograph, offering a direct, unobstructed light path.
-
Top Port (90° Angled): This port uses the internal mirror and functions like a star diagonal. It's ideal for a visual eyepiece for centering objects, or for a secondary camera.
-
Bottom Port (Auxiliary): This port is designed for specialized tools like a spectrograph calibration lamp or an off-axis guider pick-off prism.
Will the Baader FlipMirror II degrade my planetary images?
No. The Baader FlipMirror II uses a precise, surface-mirrored diagonal with a high-reflectivity multi-layer aluminum coating. Its optical quality is engineered to be on par with high-end star diagonals, ensuring that it does not introduce aberrations or reduce sharpness, even when used for high-resolution imaging with cameras that have small pixels.
How does the Baader FlipMirror II help with spectroscopy?
The FlipMirror II is a powerful tool for spectroscopy. You can keep your spectrograph attached to the main straight-through port while attaching a calibration lamp to the bottom auxiliary port. The back of the flip mirror is specially coated to redirect the lamp's light into the spectrograph's slit by simply flipping the mirror, allowing for quick and easy calibration frames without disassembling your setup.
Can I motorize the Baader FlipMirror II for remote operation?
Yes, the Baader FlipMirror II is designed for future motorization. It can be operated with an optional toothed belt and motor, which can be controlled by systems like the Baader SteelDrive II controller. This allows you to switch between the imaging and visual ports remotely from your computer, which is essential for automated observatories.
How would I set up the Baader FlipMirror II with my Celestron SCT and a ZWO camera?
For a common SCT setup, you would attach the Baader FlipMirror II to your telescope's visual back. Your primary ZWO imaging camera would be connected to the straight-through rear port. An eyepiece for finding and centering objects would go in the 90-degree top port. If you use an off-axis guider, the OAG's pick-off prism could be attached to the bottom port, providing a permanent guiding solution regardless of which main port you are using.
Does the Baader FlipMirror II consume a lot of back-focus?
The Baader FlipMirror II has a compact and efficient design to minimize back-focus consumption. However, like any accessory added to an optical train (e.g., filter wheels, OAGs), it does have a specific light path length that must be accounted for. It's crucial to check the back-focus requirements of your telescope and any reducers or correctors to ensure you can reach focus with your camera.
