Equatorial Mounts For Budget Astrophotography?

RogueScientist Motorized Equatorial Telescope mount free. (85 comments)

I have a motorized equatorial mount that is of very hefty precision design. You would have to pick it up from Santa Fe NM, but its perfect for astrophotography. -Simon.

Extracting Digital Video from LaserDiscs?

RogueScientist method of digitizing a laser disk (92 comments)

A laser disk has pits on the disk that vary in length and position in the sequence. So essentially you have a time and amplitude domain that generates a analog waveform. Why would it not be possible to construct a special apparatus that reads the length of the pits as accurately as possible and store that information in a data file with a 64 bit number for each pit with a time? Once you have this the data you have captured is digital and can use the necessary analysis to generate the image information from that data? It seems a lot better than dealing with disk players that are taking this information doing various filtering on the information and working with the generated analog frequency waveform.
