I decided to go for a challenging target the past couple of weeks. I’ve been fortunate to get several great nights for observing. This image, from my backyard, is the result of over 60 hours of photos. The nebula is an HOO palette and the stars are RGB. This target was so dim, that a single 10 minute sun through O3 showed almost nothing!
Here is a single 10 minute sub through the Ha filter. Still way brighter than the O3, but you can see why it took 30 hours per filter to bring out the final result.
