Description

The Double Cluster, captured with a T4i and 80mm ED APO with 0.8x focal reducer (480mm F6). Tried my first attempt at dithering with BackyardEOS and PHD2. I only got 28 minutes of good data before a strong fog settled and the glow from the fog killed good light, so I dropped all that data and worked with the 28 minutes. Since it's a wide star field I figured I didn't need much time anyways, just good calibration frames. I did 41 flats, dithering, and 41 bais frames to take care of gradients and noise where possible. Minimal processing.
