Dark-frame filters block all light from entering your camera, making it easy to capture fast and accurate dark frames for astrophotography.
It fits in your filter wheel and makes it easy to switch in and out during your imaging sessions. No need to cap off your telescope, and no need to worry about light leaks that will ruin your frames. A must-have accessory for CMOS and CCD astronomy cameras to eliminate camera noise and hot pixels.
This filter has standard 2" male threads for use with 2" camera nosepieces, 2" filter wheels, and 2" filter drawers/sliders.
This dark filter is made of black anodized metal to ensure a long life with no fading or discoloration. Some other cheaper dark frame filters on the market utilize a black plastic substrate in a regular fitler cell, and these can bend or crack over time. Our dark frame filter is machined as one solid metal piece. In fact, you can also use this as a 2" dust plug for 2" female-threaded astronomy accessories if you want to.
Specifications:
- Male thread specification = M48x0.75 (2" filter thread)
- Male thread length = 2.5mm
- Total length = 7.5mm
- Opitical length (same as cell height excluding male filter thread) = 5mm
- Maximum outside diameter = 50.75mm
