I built a dobsonian telescope and I want to attach a finderscope to it. I know that usually finderscopes are attached to the tube, but I was wondering if I could attach it to the top of the tube box instead as I want to avoid drilling holes into the telescope tube. Everything is in great alignment and precision, so there's nothing to worry about there. I would just like opinion on where to mount the finderscope. Thanks!
Cool.
OK, so you have a box on the tube that is near the axis of rotation? Consider where your head is going to be, and how difficult it will be to keep it there. IMO, even the best designs often don't get this right.
One home made Newtonian Dob has a longer than required tube. The finder is mounted in front of the main eyepiece so that the 90 degree finder eyepiece is right next to the main scope eyepiece. That way you can go back and forth easily. I wonder if the owner is left eye'd or right eye'd.
I'm left eye'd. My finder scope is clearly mounted for right eye'd people. How would I fix it? I'd put the focuser on the right side of the tube and put the finder above it and slightly behind.
Which eye'd are you? Which eye goes to the eyepiece? That's all.
