I'm sure many others have thought of what's described below, but I've been out of telescope stuff for many years, I'm new to this forum and haven't seen it yet. Maybe this will be an appropriate contribution in return for the wonderful help I've received here.
When aiming a scope, there's nothing I like better than getting behind it and lining it up on the target. I've used Telrad type finders and green lasers, but nothing beats what I came up with this week. I hooked up an old webcam to an old Android tablet and mounted them on my scope. The webcam is in a simple mount with three spring-loaded screws with thumb nuts for adjustment. For the tablet, I found a screen overlay that puts a red bullseye smack in the middle. The tablet is mounted just above the focuser. I just have get behind the scope once to point it at the desired object, then when take my seat at the eyepiece, that object is somewhere on the screen. I just move the scope until the object is in the bullseye. The ring around the bullseye is serendipitously about the same field of view as the eyepiece at 300-350 power.
The first image below is a result of aiming my camera into the eyepiece simply to capture the field of view, NOT to take a photograph of Jupiter and its moons.
The second image was taken immediately after the first, so it shows where Jupiter appears in the bullseye. You can just barely see the targeting red dot in the middle of the bullseye. Jupiter is not superimposed on it because Jupiter is not centered in the eyepiece. So you can see just how much give there is.
The third photo shows how the tablet and webcam are mounted on the scope. The webcam is in the light colored wood frame at the top of the screen just over the tablet. Just visible is one of the adjustment screw-springs.
The tablet is a Dell Venue 8, but any cheap and generic Android tablet will do. The USB camera app is USB Camera by 沈垚 / ShenYao China. The bullseye is Screen Overlays by Andrea Bresolin.
I highly recommend disabling wifi before running such apps, otherwise you'll likely see ads. Or pay $5.49 for the pro version of USB Camera.
The webcam is a Microsoft Lifecam 3000 with the lens removed and replaced with a longer lens more appropriate for high power use.
