Here are my two main telescopes. The telescope on the left is an Obsession 18" ultra compact dobsonian reflector. This telescope folds down to a compact size that fits in the back of a car, which allows me to take it to dark observing sites away from city lights. The telescope on the right is my primary imaging telescope--a 14.5" Ritchey-Chretien from RC Optical Systems in Flagstaff, Arizona. The primary mirror is "ion beam figured," a special process that achieves optical smoothness down to the molecular level. Notice that I have the truss model rather than the tube model. The telescope is mounted to a Paramount ME mount by Software Bisque. It is a premium mount that easily supports my payload (nearly 90 pounds of telescopes and camera), and can be operated robotically. The small telescope on top is a Takahashi Sky 90 apochromatic refractor. I use it for wide-field imaging. The black pier beneath the Paramount ME mount is an ATS portable pier. All of this equipment rests atop JMI 5" Wheeley Bars. I roll the equipment out of my garage onto the driveway for each imaging session. This requires me to polar align the scope each night, which takes several minutes. I live in Springfield, Missouri, and the skies have a limiting visual magnitude of 4.5 to 5 on the best nights. I use the SBIG ST-10XME and STL11000 CCD cameras for imaging, and I control my telescope, camera, and mount using Maxim DL and TheSky6 software. |

| Takahashi Sky 90 (3.5") apochromatic doublet refractor on a Takahashi EM200 German equatorial mount. This telescope, with the SBIG ST-10XME CCD camera, produces a wide field of view (85 x 126 arcminutes). I use a Takahashi flattener/reducer to reduce any distortion at the edges of images. This telescope is now mounted on top of my 14.5" Ritchey-Chretien. I use it both as an imaging telescope and a finder scope. |
