General

This manual provides observing guidelines for the 1.2m Oskar-Lühning-Telescope (OLT) equipped with the CCD camera. It describes the oltcontrol software to operate telescope and camera written by Hans-Jürgen Hagen.

The OLT is currently operated with an AP8 camera from Apogee Instruments for direct imaging. The camera is equipped with a SITe 1024x1024 CCD chip with a pixel size of 24$\mu$m, allowing imaging of a 5.4'x5.4' field with a resolution of 0.32''/pixel. The CCD is cooled by thermoelectric cooler with forced air. Broad-band Johnson filter B, V, and R, and a narrow-band H$\alpha$ filter are provided. Guiding of the telescope is done with a second CCD camera (Apogee KX260) mounted on a movable carriage. The CCD is a 512x512 pixel array with 20$\mu$m pixel size.

Figure 1: OLT control main window. Below the main button bar the window is divided into sections main camera (control of the main CCD-camera), guiding camera (control of the guiding camera), dome (dome control), sky (telescope pointing control), and telescope (with display and operations panels).
