NGC 604 Diffuse nebula and star forming region in M33. Taken Nov 30, 2006 in H-alpha with a DSI Pro
II on a C8NGT operating at f7 for an effective focal length of 1400mm. The H-alpha subframes were 3
min. each for a total exposure of 117 min. The color data was derived from my M33 shot and used
for the HA:R:G:B composit. Captured with Envisage, calibrated and sigma combined in Iris with other
processing using PixInsight LE and Photoshop CS.
