This is my second attempt at the Eastern Veil. This one with a William Optics 71GT with Stellarvue 0.8x focal reducer/corrector. It was done over the course of a few weeks. In the middle of the imaging session, I received my fresh 10Micron GM1000, so this became my first experiment with it. Thus, the first 20 or so frames of Ha and OIII are done guided with my eq-g, and the last 30 of each are done unguided with the 10Micron. The eq-g's guiding issues showed up in full detail with the OIII, but not so badly with the Ha. Starts were pretty much perfect with the 10Micron, however.

This is also my first venture into Pixinsight processing. When people said 'steep learning curve' they were not joking. I finally had to just say 'no more' on this one after taking days trying out new things. I personally think it looks a bit overprocessed, so I might go back and tone stuff down when I become a bit more adept at this program.
