Features

 

Micron-Precision Filter Positioning

Both the Standard and Self-Guiding versions of the STXL filter wheels incorporate the same micron-precision filter positioning mechanism as the STT Series cameras.  When taking flat field frames of filtered images, the flat field frame must show exactly the same optical characteristics to be the most effective. If there is dust on the filter, or uneven illumination caused by the filter, this must be represented precisely as seen in the light image to be corrected by the flat field frame. The STXL filter wheel is designed to provide a new level of accuracy when taking flats through filters by repositioning filters to within a few microns every time. This allows the imager to take extremely accurate flat field frames even after rotating the filter wheel several times, or even after a loss of power.
