AUTOSTAR CCD PHOTOMETRY 33
APPENDIX A
Modifying the DSI Pro Camera
Introduction
The color versions of the Meade Deep Sky Imager (DSI) CCD
camera cannot be used for astronomical filter photometry, but the
monochrome DSI Pro (and DSI Pro-II) can. To do serious work
requires some simple modifications to the camera. These
modifications include replacing the stock filter slide with a filter
wheel (or turret), and adding a simple thermoelectric cooler (TEC).
With these modifications, the DSI Pro (and DSI Pro-II) provide the
means to do professional-level astronomical photometry with a
modest telescope, even in a light-polluted suburban location. This
chapter describes these modifications and what is needed to do
BVRI CCD photometry with the camera.
