Hi
With a new update to Star Atlas Pro,
http://www.skylab.com.au/version_6_2.html
I went after some of these new H alpha regions. Heres RCW 102, the large faint arc near top, with the much brighter Planerary MZ3 lower left.

1 x 10 min and 1 x 15 min ISO 1600, EOS300d, 10 inch F5.6, baader UHCS and Lumicon Coma corrector.
I have never known that MZ3 was near a larger faint H alpha region. With the new Star Atlas pro update there are literally heaps of new H alpha regions to be imaged that Ive never known of before.
