Hi Helen, Good to hear you are making some progress. I assume you are now using the faster lens (6mm f0.8) coupled to a Watec 902H2 Supreme. This document provides recommendations for the various settings on the camera: http://nemetode.org/Technical%20Notes/TechNote%2001%20Watec%20Cameras%2020150127_03.pdf Can I just confirm that, having applied 12VDC to the connector on the lens, the iris opens fully (you should be able to see this happening as it takes a second or so for it to open) - and disconnecting the 12VDC, the iris closes again. Assuming the iris opens fully, you should get a reasonably bright image that in turn means that brightness and contrast can be reduced (thus reducing noise levels). Any questions, I can talk you through them - my mobile in on my 22nd Mar email. Best regards William

Hi Helen, I have a selection of fast (f0.8) lenses that are ideally suited for meteor work. They're suitable for 1/2" sensors and come in a range of focal lengths (3.6mm to 12mm). Would recommend starting with a 6mm. Please send me a PM if you would like more details. William (co-founder of NEMETODE).
