at the moment, the toucam is operating as out of the box, I managed to get the movie capture as it slid by and then stacked in registax. The modified bit is that
http://www.telescopes-astronomy.com....am_philips.htm put a switch in the front of the toucam (would prefer it to be at the back so that the adapter can fit properly into the focuser, i have subsequently cut the switch with some pliers! ). This switch basically sets up the toucam's exposure to be controlled thru the parallel port. A free imaging program
http://www.precons.com/iis/downloads...m/Desire40.zip then can take as many images as you like at whatever exposure time you want.
I can not use this mod at the moment when the toucam is in prime focus (where you unscrew the toucam's lens, screw in a 1.25" adapter, remove any eyepieces from the focuser and put the 1.25" adapter into the focuser) it causes the telescope to act as a giant telephoto lens for the toucam. In prime focus, the toucam is viewing at aprox 6mm. The sky simply rushes by!! As i have an unmodified dob, i cannot track, therefore long exposure for me at the moment is not an option.
I knew this when i bought it. It is an investment in the future. When i can track with my scope either thru a eq mount or a

then i will employ the long exposure times.
