Hey thanks guys
Paul, the settings for the Lagoon: (I use Desire to capture, & with the capture settings it refers back to the standard software Philips Vrecord)
Brightness 55%
Gamma 95%
Gain 15%
Maxed out on exposure of course ( 1/25th) @ 5FPS.
The Lagoon was the first shot I took after drift aligning, but not accurate enough so I had to stay under 30 second exposures to stop star trailing. Taken at 20 seconds each with about 20 captured.
The swan & M42 were captured at longer exposures & therefore different gain & gamma settings. From memory, 10% gain 70% gamma.
Desire has optional amp off/on time settings as well as others & one will have to experiment in this area extensively, finding the best settings for the webcam used, that took awhile to nut out but I got there in the end.
One of my major problems is having to move my mount out of the driveway each night I've finished, so I'm making a pier to fix that wee problem; I will be able to get the car out with at least 5" to spare each side
I can then drift align to my hearts content to get it accurate enough to get up to 60-90 secs.
