Schmidt-Newtonian collimation different?
I've become comfortable checking collimation on my Dob. But I'm wondering if collimation is done the same way on a Schmidt-Newtonian. I just bought a used 6" Meade LXD75 and after getting it home and looking through my site tube, the secondary was not centered at all to the focus tube. Anyway (I'm rambling)... I thought I'd read somewhere that the secondary mirror should be 1/8" off in two directions from regular newtonians??? Does that sound right?
I guess what I'm asking is can I collimate my new SN like I do my Dob?
