Wow
That was a phenomenally good summary, concise and extremely useful.
You are a rare author. Can I ask if you write any books?
I especially liked the short bit of history you inserted into just a few words. I have heard of Tv and Av, but never the abbeviation Sv.
I had often wondered why Tv and Av for "Exposure Priority" and "Aperture Priority" were not Tp and Ap, now it all makes sense.
The Overrides option still causes me a little confusion. I gather a good script just sets default on startup and I shouldn't be 'Overriding the Overrides' in the beginning, just set the camera on P mode and shoot. Twist the dial on top to 'P' and go.
The usage of the ND option also leaves me a bit in doubt, sounded like ND on for Star Trails is good and ND off for everything else. I guess I'll have to experiment a bit.. which is half the fun.
The CHDK description page for the Focus seems all over the map with depends on camera and exceptions to the rule, AFL and MF.. I may just have to struggle with trying to learn how to set it at Infinity.
Thank you for your very informative summary and for pointing me at the meteor2.lau Script.
I think it will be very useful.
I start my drive to West Texas tomorrow morning before Sunrise, its a 9 hour drive, but its something I've wanted to do for a long time. Remote dark skys on a lonely Mountain top with a Really big telescope.
I'll post images of whatever I get.. good or bad.
