The advantage of a Toucam!
The tiny chip only shows a close up of the centre of the FOV, acting as a 6mm EP. So, what you see on screen is just like a 6mm EP.
Place the curser on a star, or the centre of the object itself, or open a guiding program and use the programs crosshair, and BINGO, an illuminated reticle
Well, that's how I do it anyway.
Don't have to stare into an EP, just sit back and see if it moves on the monitor.
