My home backyard observatory was custom designed and built by Gardensheds Inc of Lambertville NJ ( The precision-engineered roll-off roof allows ready access to the night sky when weather permits. The main telescope for imaging is an AG Optical corrected Dall-Kirkham design with 12.5 inch diameter mirror and integral thermal control system. The fast f/6.7 focal ratio and very wide flat-field of this telescope are ideal for astrophotography. The Software Bisque Paramount-MX sitting atop the custom Advanced Telescope Systems pier ( is a state-of-the-art robotic equatorial mount controlled by TheSkyX software. The CCD camera is the Santa Barbara Instruments Group ST10-XME with the KAF-3200 sensor and thermo-electric cooling.
