Modded webcam vs a real guidecam
I am using a logitech C270 webcam as a guidecam on the cheap with PHD2. Even after playing with the gain and exposure of the webcam props, it really only shows me pretty bright stars such that there might not be one that is usable in the direction of the imaging scope. Would a proper guidecam such as an ZWO ASI120MC or MM be more sensitive and show more star to choose from?
I do some basic imaging with my Canon EOS M6 on a Star Adventurer mount. For my 300mm FL shots I have found that guiding has a marked improvement on the outcome. I tried to do it on the cheap by modding the logitech C270 with a 3d printed 1.25 inch nose piece and a 50mm orion guidescope I got on icetrade. It's not too bad a situation at the moment as I can point the guidescope in a different direction to the dslr using a ball head adaptor. But if I decide to get a WO Z61 or 71 at some point I'd like to go to a piggyback config and I might not get a star to use in the fov. I'm happy to buy a proper guidecam but if it's not going to give me more choice then there is no point.
I do the RA control from PHD2 via an ardiuno ASCOM/USB-ST4 convertor.
Thanks
Dave
