I made one and used it with my T3i. I found on my Mead scope I had to use the Barlow or I could not get anything in focus.
Awesome! The few shots I've taken with mine have spherical aberrations and some focus issues too, but its fun nonetheless!
Thanks for sharing!
I'm such an ameture when it comes to both astronomy and photography I don't know if I would notice spherical abberation.
