Description

This is an "All-Backyard" project - all data from my bortle class 9 backyard under the moon, including Ha, S-II, O-III and R/G/B star layers. It took 7 nights to collect all the data for this project. It's quite unusual - one whole week with clear night sky. Right after I failed miserably trying to capture some data for the SH2-129/Ou4. Now I do admit that some targets are not practical for backyarders.

Learned quite a lot from imaging and processing the RGB stars. Intentionally, the stars are decreased a lot to expose more nebulosity. Three versions are made and uploaded - star spikes, no spikes and no stars. Don't know why one is better.

Comments are welcome!

Thinking about Western Veil as the next target.
