Ah! Pixel & frame size. That's the answer, of course. Thanks, all makes sense now.
So just to recap:
I currently have an 8" f/5 Newt on a NEQ6, shooting with DSLR. I also have a spare laptop with PHD2 installed, and a cable that goes from the mount's serial port to USB. I need a guidescope & camera and a way of attaching them securely to the imaging OTA.
Once everything is acquired and solidly in place & properly balanced, I do a normal drift alignment and 2- or 3-star align. Then I connect the camera's ST4 port to the mount, and its USB port to the laptop. Then I connect the laptop (USB) to the mount (serial). Then I run PHD2 at which point magical wizardry magically happens with magic and I can take 5 min subs forever.
... Right? Or am I missing a few steps? Something about EQMOD (which I'm completely unaware of)? And where do programs like Stellarium come into play, ie how do I locate targets?
Sorry for all the questions,thanks for all your patience!
