Here’s my first ever narrow band image using the Hubble pallet. This is only about a 3 hour exposure. I wanted to collect more data, but a multi-day storm has come through CA and there won’t be a clear night for about a week, so I figured I would get this done as best I could and consider it version 1. Here is a great tutorial on how to compose Hubble Palette images using data collected with Ha, Oii & Siii narrow band filters. I’ve gotten most of the bugs out of my system, but my tracking is still not 100%. I’m currently dealing with a 2 arc second guide error peak to peak, and I’d like to get that down to 1 arc second. Other than that, things are working pretty good.
Approximately 3,000 light years away, the Elephant Trunk Nebula is part of the emission nebula IC 1396. It was given this name as the gas cloud resembles the head and trunk of an elephant. While the entire nebula covers 5 degrees of the night sky, the trunk part of it is estimated to be 20 light years long.
