what telescope was the CCD hooked up to?
I'm not sure...
I don't own a CCD, I was going to buy a $330 Imaging Source CCD, but I have no idea how you hook them up to telescopes, and I don't even have any laptop yet or anything. Most of the CCD's also have 2" nosepieces, which I assume goes into the eyepiece? I have a Celestron Nexstar 114, and that uses 1.25" eyepieces, filters, and everything.
Someone also said you need a much more sturdy telescope, and when you upgrade to the good ones... They are $3000, more than some of the decent CCDs out there... So you might as well then get an SBIG or something.
And the 114 is an AltAz mount, so it wouldn't work with the celestial sphere or something, it would move the wrong way. I'm not sure what mount I'd need then...
