Logitech Quickcam Pro 4000 & Astronomy
If you want to get into using a webcam for astronomy, then most people recommend the Philips SPC9000NC webcam, but luckily I already owned a webcam which I use for Skype, from Logitech called a Quickcam Pro 4000.
I knew that webcam adaptors existed so that you can insert the end of the webcam straight into the telescope eye piece area and then use a laptop to record your footage. What I needed to know was if the Quickcam Pro 4000 could be used with one of the stanard telescope webcam adaptors.
I decided to try and take the Quickcam Pro 4000 apart, this can be easily done by inserting a screwdriver into only one of the holes on the webcam and unscrewing the screw in the webcam.
Now prise apart the webcam and then you should be able to take the webcams main front ring off and then unscrew the lens out of the webcam.
This image below shows the webcam after I have opened it by unscrewing it and then taking off the rubber surround, I have then just screwed the webcams lens back in.
Now you can unscrew the lens from the webcam, which will leave the CCD sensor open to the air. It is advisable to not let a lot of dust get into the webcam, so do not leave the CCD chip in the webcam open to the air for too long.
I then purchased a webcam adaptor for £20, luckily the webcam adaptor I required for the Quickcam Pro 4000 was the same webcam adapter which is used for the new Philips SPNC9000 webcam.
You can also purchase ends for the adaptor or filters that screw into the end of the webcam adaptor in order to protect the CCD sensor from dust.
Now you are ready to try your webcam in your telescope and get some photos and video.
All you need to do is insert the adaptor end into the telescope eyepiece area, and use some video capture software to get some great images.
