Two 'bright' comets in one shot. Stack of two 2-min subs taken with Canon 400D piggybacked on 4.5" f8 reflector on EQ1 and hand-guided with NexImage. Tuttle is green spot at left. Murky-brown from sky-glow from Albury-Wodonga
. Rough levels adjustment, crop & re-size in PS CS2.
Tuttle appeared as a small round smudge in binocs, bigger smudge in scope, and no sign of bright core or any tail. Holmes was naked eye (just) and huge!! Excellent in binocs, but didn't put scope on it as I know the magnification kills it.
