Using a Philips900nc;a 5x powermate & a 12"LB for planetary photography. Do I need extension tube to bring image into focus and what length?
Anyone with experience out there?
Thanks
No experience with the LB stuff, but in my 10" if I can focus an eyepiece first in the Powermate (I use both a 2.5x and a 5x) then the ToUcam is close to being in focus as well. Best suggestion is try it first.
