1: Introduction

When performing research you often find that the instruments needed are not available as standard products, especially in the field of astronomy. I have previously written about the astrograph at Saltsjöbaden Observatorie, you can read about it here:

• Observatory Saltsjöbaden

The Saltsjöbaden astrograph was manufactured about 80 years ago. That was 1930s solution to this problem, I now continues with a new article about another special camera. This camera which I will talk about now is an ongoing construction and continuous manufacturing (2008).
