Well, I was 20 feet away from Ivan, same night (01/26)(27F). We have the same camera, a 20D. However, I was using a Takahashi Epsilon 160 on a G-11 mount. I took 9 pictures of 5 minutes each at ISO 1600, processed with Photoshop with my own version of flats. No crop.
I'm like Ivan, I would like to see more reds from H-Alpha one day...
