my f5 10" fl1250 gs reflector with the 2" crayford refused to do any eyepiece projection with the toucam. could not get any focus at all.
Matt from T&A was at a loss as well. Seems to work well that eyepiece projection unit in refractors, but not my reflector.
Also the t thread adaptor for the toucam would not work with digi t to produce a focussed image. ie when you literally screw the t thread onto your eyepiece and then straight into the toucam without the lens.
No-one seems to know why, Matt has machined the t thread down and machined the eyepieces down to make sure that the lens of the eyepiece is really close to the ccd of the toucam, he offered me this, but every eyepiece i owned would have had to be machined!
I think it was bert that suggested going the other way, have 95 - 140 mm between eyepiece and ccd, but again starting to get expensive.
the williams optics digiscope at $69 gives me low mag for long exposures, and the prime focus adapter will give a 5 or 6mm fl for planets. I think i am covered!
I have installed the raw colour mod, which really tightened up the stars, so i would say yes you could get away with the exposure modded at a say 1/10 of a sec exposure for guiding. but any more than that and you are you starting to be too slow for response for guiding??? i can't guide so i don't know???
the minimum requirement are more for the software that comes with it. there are imaging this and that, which at the end of the day, if you have photoshop, don't bother installing anything else.
just a thought, for the long exposure to work the software needs the parallel port to send two signals to the toucam to say "stay on" for 2 seconds etc. the image comes back up the usb port. now for guiding, i would not think you would find guide software that would integrate well with the parallel port and usb. K3ccd does for imaging part, but in the guide section, i have seen no setting for the printer port!!!
you may have to write your own.
I have started, but i will be 6 - 12 months before i have integrated tracking, guiding, long exposure etc etc in one imaging software program!
food for thought.
At star camp, i am having a big hitout on the toucam with some of the tracked scopes hopefully, so i can answer more questions then
