Patrick Winklers Observatory

Roll-off Roof Observatory

At the beginning my equipment was small and I only took photos mobile. But with the continuation the demands grew and the idea of ​​building an observatory came up. Also, sitting in the cold all the time and loading/unloading the equipment was laborious. So it was a matter of finding a suitable location that was not too far away from home and offered ideal conditions.

My observatory is fully automated and controllable via the internet. In addition, it is equipped with an
All-Sky-Camera, SQM, weather monitoring system, a seeing monitor and a lightning protection system.

Size: 3 x 3m
Location: Joglland / Styria

Telescope and Mount

My current telescope is an ASA 400 16" RC (Ritchey-Chrétien) with a focal length of 3200mm (0.24"/px) on an ASA DDM 100 direct drive german equatorial mount with absolute encoders (load capacity 100kg). For imaging the night sky i use a ZWO ASI 6200 MM Pro camera with a FLI CFW5-7 filter wheel.

Additional devices

When doing remote astrophotography it is important, that you have as much information as possible about the conditions from your observatory site. Therefore I installed - as mentioned above - an All-Sky-Camera, a weather monitoring system and a seeing monitor. These devices provide information about the degree of cloud cover, temperature, wind, relative humidity and precipitation. In addition, the All-Sky-Camera provides an up-to-date image of the sky and the seeing monitor measured values ​​about the current seeing conditions.

All this information helps to compensate for not being there and to better assess weather situations. And to be honest, I don't want to miss all of these little helpers.
