I used my TV-76 and the TV 0.8x reducer for this pic that I took from my porch ... He was about 20 yds away from me. While not exactly a portable setup for heading into the woods, I'm certainly happy with the results!

I was following the buck up past my observatory and suddenly there was two does and two fawns right in front of me.

You should see how much detail can be seen in the full-rez version!
