Here one I made ages ago on my old Refracter.
Made out of some scrape aluminium bar .
Note the camera strap raped around the scope just incase.
Good job on yours there.If it works and saved you money that's all that counts.
Try a free ware program called Irfanview to get your pics smaller..

There is a very good resize and batch resize and compression function in it.
