It appears this crossing will last less than a second.
You are correct. Much less than one second. I'll have a device hooked up to the system that receives the time signal from the GPS constellation and puts it on the video. It's good to .001" so from that I should be able to say exactly how long the transit takes.
Will you have a real-time display for the video? The video signal from the camera feeds into a combination TV/VCR so, yes, real time video will be available.
How magnified are you planning to observe? My C-5 with an f/5 focal reducer gets the focal length down to 625mm. Unfortunately that still does not show the entire disk of the Sun so I'm looking around looking for something around 300mm. (Ideas, anyone?)
What do you expect to be able to see? Probably not a lot. Not only will it cross the disk very quickly but because it will be fairly low in the sky it will be about 1,885 km away which will make it pretty small. I saw a lunar transit a few weeks back using just my eyeball and ISS was just a blur.
One of these days we're going to get a transit high in the sky which will put it less than 400 km away. Much bigger target then. Personally, however, I'm looking for it to cross a crescent Moon when it's high in the sky. That would make for a very pretty picture. Patrick
