Temperaturabhängigkeit des photographischen Farbsystems der Tautenburger Schmidtkamera

The coefficients of the colour equation for the blue magnitudes determined with the Schmidt telescope at Tautenburg show a correlation with the temperature in the open air. Possible causes if this effect are discussed.     

Die Herabsetzung der Schwärzungsgradieten astronomischer Aufnahmematerialilen durch das FAH - Verfahren

Photographic astro-plates were FAH-attended, in order to prevent developments effects by a large gradient of the characteristic curve. The influence of the FAH attendence on the photometric error was researched too.     

Nova Cygni 1975. I. Beobachtungsmaterial und Entfernungsbestimmung

From the strength of the interstellar H- and K-line in the spectrum of Nova Cygni 1975 its distance is determined to 1.2 kpc.
