Unlike most filter drawers, the OGMA UFD allows the precise positioning of an Off-Axis Guider, ensuring optimal performance and ease of use.
What sets the OGMA UFD apart is its versatility. You can connect it to a wide array of cameras either by using screws on both sides or the large thread around the center.
You can download 3D-printing models of the drawer to accommodate filters of different sizes and threads.
The OGMA UFD adapts to your specific astrophotography needs now and in the future.
When using an OAG, it's crucial to position the OAG's prism exactly above the camera sensor. Traditional filter drawers often pose a challenge in predicting the final prism position of an OAG because they are connected to the imaging train using a large thread at the center. While tightening the tread, it is hard to know the final position of the prism.
This OGMA UFD can be connected using screws that are precisely placed to make sure that the prism of the OAG will fall at the required angle, consistently—no more guessing where the prism will be after tightening the threads.
Compatibility
- All cooled OGMA cameras
- Most cooled cameras from Touptek
- Most cooled ZWO cameras featuring six M2.5 screw holes distributed around a 62mm circumference on the front face around the sensor
- Some Player One cameras
Back Focus Considerations
This product can take either 20mm or 21mm of back focus.
The main body of the UFD has a width of 20mm.
An included thread adapter/extender adds 1mm of back focus and adapts the thread from M54 (F) to M48 (F).
