What is the main purpose of the Baader 2"/2" Inverter Ring?
Its primary function is to solve backfocus issues by replacing the standard 2" ClickLock clamp on compatible Baader star diagonals. This creates a shorter, direct-threaded connection for accessories like the Hyperion Mark III Zoom eyepiece, allowing systems with limited focuser in-travel to reach a sharp focus.
Will this Baader inverter ring work with any 2" diagonal?
No, it is specifically designed to thread onto the body of Baader Planetarium 2" star diagonals that feature a removable ClickLock clamp. It is not a universal adapter for other brands.
How does the Baader 2"/2" Inverter Ring help me reach focus with my SCT and a binoviewer?
By shortening the overall light path, this adapter can provide the crucial millimeters of in-travel needed to bring a binoviewer to focus in a Schmidt-Cassegrain Telescope (SCT). While not a guaranteed solution for all combinations, it is a key component for creating the most compact connection possible between the telescope and a binoviewer setup.
Can I use 2-inch filters with the Baader 2"/2" Inverter Ring?
Yes. The ring features internal M48 x 0.75 threads, which is the standard for 2-inch astronomy filters. You can thread a filter directly into the adapter, placing it securely in the light path.
Is the Baader 2"/2" Inverter Ring required to use the Hyperion Mark III Zoom eyepiece?
No. The Hyperion Zoom works perfectly in any standard 2" focuser or diagonal using its included barrels. This inverter ring is an optional, problem-solving accessory used only when you need to create a direct-threaded connection to a Baader diagonal to save backfocus.
How do I install the Baader 2"/2" Inverter Ring?
First, unthread and remove the entire 2" ClickLock clamp assembly from the body of your Baader star diagonal. The inverter ring then threads directly onto the exposed threads on the diagonal body, providing a male 2" thread onto which your accessory can be attached.
