Using a cheap 50mm refractor as a finderscope?
I have been having a go at webcam astrophotography of Jupiter with my 10-inch GSO dob. I've been following Iceman's article which is a great help, but as he says, it is very hard work repeatedly relocating the planet through the finder. I was thinking that a higher magnification finder would help a lot (mine is an 8 x 50).
As a cheap solution, could I use a department store cheap 50mm refractor as a finderscope? Then I could comfortably get 20x or 50x magnification rather than 8x. The view would be terrible but it would be good enough to centre on the planet. The aperture would be the same as my current finder, so it could hopefully just fit into the existing finderscope holder. I could use the existing screws to align it. But maybe it would wobble too much?
Any ideas if this would work or not?
