Description

I captured this target during a waxing gibbous moon while I was troubleshooting the guiding of my mount. I decided to process the data just to see how good I could make bad data look.

The signal to noise ratio on the individual subframes was terrible. The stacked data was only marginally better due to heavy LP and the 1.3 hour integration time. The biggest challenge was the incredible amount of noise. To achieve the image seen here, I had to beat the data mercilessly until it yielded an acceptable result. ;)
