First, I tried retried the region around Antares that I had attempted last month. Using the new 200mm zoom lens, I took a series of 10 min frames. I was disappointed in the SNR of the final image. I was not able to stretch the image much before it was swamped by "hairy color noise."

Danielle imaged the Pipe Nebula with a 400mm lens. She did not have a guider that evening and the 6 minute frames were a bit long for the PEC of the Atlas mount. She processed the frame with the least tracking error.
