The OGMA 2’’ Zero Light Leak Filter Holder is an affordable option to place a 2-inch mounted filter in your imaging train.
Modern astrophotography sensors are extremely sensitive to light. That’s why the most minor light leak could ruin an entire night session of astrophotography.
The OGMA filter holder is relatively similar to a product called Filter Drawer. While a filter drawer is designed with convenience in mind, this filter holder has been designed to provide a similar functionality while totally preventing the entry of stray light into your imaging train that sometimes happens while using a filter drawer.
- Zero light leaks.
- It's probably the most affordable solution for adding a 2'' filter to a dedicated astronomy camera.
- Version 2 can also work as an adapter between threads M42, M48, and M54, commonly found in astronomy equipment. The version 1 couldn't be used as an adapter for M54 threads.
Specifications
- Material: High strength aluminum
- Filter diameter compatibility: 2 inch
- Telescope side thread: M48x0.75 (F)
- Internal thread (for filter): M48x0.75 (F)
- Camera side thread: M42 x 0.75 (M)
- Thread that connects both parts: M54 x 0.75 (M & F)
- External diameter: 59mm (v1 was 62mm)
- Internal diameter (clear path): 35mm
- Width (for back focus calculations): 21mm
- Weight: 72gr
