Additional blind filter designed for Astrodevice filter drawers. With the blind filter you can take dark and bias frames without removing the camera from the telescope. To cover the sensor, just insert the blind filter instead of the filter slider.
To maintain the correct position in the drawer, the slider is equipped with two side magnets.
One blind filter is included with the Astrodevice drawers. If you would like to have a spare one, e.g. in case you lose your original one, you can buy an extra one here.
The slider comes in two variants, differing minimally in size. The first variant works with drawers FD 900 M87 and FD 900 M42 and the second with drawers FD 860 M87 and FD 860 M42. Depending on which drawer you have, choose the appropriate slider variant.
The base of the product are 3D printed elements made of PET-G CF filament (polyethylene terephthalate glycol-modified reinforced with carbon fiber).
