Canon LX mod

Is there a generic Driver for a USB Serial converter hooked up to the LX mod cable ?

I've had it all working but then overwrote the 350D driver/software with 400D and surprise surprise, the LX converter can't be found.

Nebulosity sees the camera and works in 30 second mode but doesn't see the LX.

If Neb can't find it you may just need to change a COM port number in the Neb settings - the port number will change if you plug the USB/Serial adpator into a different USB port.

If you have really lost the USB/Serial driver you would get a "New Hardware" message when you plug it in.  Then you will almost certainly need to have a specific USB/Serial driver.

What a plonker.......................

COM ports - Now sorted, cheers Mark

If you are using Nebulosity, I highly recommend the "Fine Focus" routine to get your focus correct - I demonstrated this to Fay at Kelling.

Take a preview image, hit "fine focus" and select a brightish star near the middle of that image.  It comes up with a new window and will download an image of just that star in a very quick endless loop while you adjust focus - it will display the star and a couple of statistics to help you get it spot on.   Can also be used in conjunction with a Bhatinov mask (but that may confuse the stats).   Exposure time and ISO can be adjusted on the fly while you do this.

I use a Bhatinov mask to get as close as possible then remove it to do the final "tweak".

Thanks Mark I'll give that a go, never used fine focus - which probably explains a lot

Yes, was really pleased Mark showing me that
