I just completed work on modifying a Lifecam HD to work as an astroimager. The work involved removing the front lens and reassembling the camera in an eyepeice extension tube. You can find detailed instructions on how to do this on the web. It looks a lot harder than it is. The hardest part was getting the lens assembly off the circuit board; the screws are very stiff. My standard mini screwdriver did not have a long enough shaft to give the leverage I needed to get the screws out. I managed to borrow one with a long and thick plastic handle; it worked very well. My tests with the cam imaging interior objects with a camera lens indicate that the imaging chip does well in low light and noise seems to be well controlled, especially for a CMOS imager. Stay tuned for details on testing; so far, the weather is not cooperating (of course).
And before I forget--seasons greetings to everyone who stops by this blog!
