In the camp at the Rotunda Pass, my plan was to acquire hours of light on the Heart and Soul, but the sky thought otherwise. I squeezed out about 8 fair exposures, 4 being with good and 4 with decent transparency (ie less contrast). So the instruments: Canon 1100D mod, 8×3 minutes, ISO 1600 at 200mm F/4 on the HEQ5 mount. I reprocessed the picture with the new star removal tool I developed a few days ago.
