I filmed Jupiter with my Nikon D5100 mounted on my telescope with two stacked Barlow lenses (2x each). Total Focal Length is 4560mm. Looking to extend this 6840mm with a 2x stacked on a 3x barlow.

This is the setup I used:

I also Used a Bahtinov mask to reach perfect focus. First time doing this, the result is amazing...
