What I've been doing lately is working many hours to improve the camera control softwawre - SebebTec. I am making it more reliable, and adding more features. Next on the feature list is a Starlight mode. Really it is just a long time exposure that will engage when it detects the scene has become dark after sunset. Now we can watch the moonrise and see the stars track along the night sky.
I can hold the camera eye open for 60 seconds. I'm working on setting the ISO to 800 which for some reason doesn't seem to 'take'. So more experimenting is needed. It does do a pretty good job though as it is. Soon we can see how well it works.
