CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
doesn't change. wat u would be more interested in is how much larger the image becomes. take the area of the film/area of webcam image sensor. so if u have maybe a 1cm x 1cm sensor, u will get an image maybe ~2.5x larger.
How does the sensor size relate to the image size?
My Creative webcam sensor is very small.. something like 5x7mm. I get an image that is roughly equivalent to the view through a 2mm eyepiece.. I'm trying to figure out what magnification my webcam/scope combination gives me.
hmm...sqrt(5^2+7^2)=8.6mm , that is the size diagonally. divide focal length by the diagonal size, 2200/8.6=256x, that should be ur rough magnification. wat scope and wat focal length?
