Basically you view a in-focus star through a 4x powermate or barlow/equivalent with a webcam/planetary/guide cam (not a DSLR) and Metaguide stacks 10 or more frames continuously to form a live video of said star, but because it is stacking it the seeing doesnt matter anywhere near as much. Then you adjust screws until the star looks like a perfect dart board.
I have a hubble. It is only useful for coarse collimation (ie making sure the secondary is roughly centered in out of focus star image to form a donut). As such it is pointless, because that is super easy to achieve anyway with any star under any conditions (except for clouds  ). |
ah ok krishan, i have a lodestar mono and my brother has an orion ssag, i looked up this metaguide site but they did not mention either of these two cams, what would you suggest? / bit disappointed about me hubble 5 star there fella ha ha!
