QSI 500 SERIES USER GUIDE

Internal Color Filter Wheel

A five position filter wheel is available for some models of QSI 500 Series cameras. The

filter wheel is designed to hold five standard 1.25" filters, and on some models, optional

unmounted 31mm filters. The following image shows filter positions 1-4 occupied by red,

green, blue and luminance filters respectively. Those are the standard filter positions if your

camera was configured at the factory with LRGB filters.

Note the reflection of the complementary colors

with this set of LRGB dichroic filters.

Note: QSI offers LRGB filter sets from a number of respected manufacturers, as

well as other specialized filters for astronomical imaging. Alternatives can be

specified at the time of order.

The filter wheel is designed to be removed and replaced easily. After detaching the camera

cover, the filter wheel can be removed by loosening a single shoulder screw. This allows the

user to have additional filter wheels populated with different combinations of filters and

interchange them quickly while operating in the field. See the Care and Maintenance

section for details.
