Okay, so I got this idea from YT about a tilt laser jig; it's shaped like a square; camera stack goes on top, face down, so much less chance of camera droop than if I use a horizontal jig; laser shoots at a steep upward angle, bounces off sensor, to the paper, so I can observe and remove tilt
Like this, (and I named the top board, A, and the bottom board B, to help you understand the questions I'm about to ask):
My first question is, what happens if top board A is not parallel with bottom board B; I understand that you can place a laser anywhere, for this tilt adjuster, no matter how steep the angle, as long as it hits the sensor and bounces back, but I'm concerned if the "reference board" (A) is already tilted relative to the base board, wont it cause the jig to also display the tilt being caused by board A along with sensor tilt, and therefore make my whole jig useless?
and that brings up the next question:
if the top board has to be perfectly parallel with the bottom board, what is the tolerance for that? millimeters?
I don't want to pay 250 euros for the AstroPrecision tool, it's just too overpriced, I doubt the actual build costed more than 100 euros, seems greedy
so I would appreciate any help on building this rig
and, if anyone is wondering, in the place of the black circle (or hole), that can be seen in my design, I plan to place a spare 2" eyepiece holder that uses a compression ring, to hold my camera stack in place (it came with my astrograph, but I'm not using it; it's the 2nd adapter from the back, in this photo https://teleskopy.pl...kar_65phq_3.jpg)
thx in advance
