NGC 6946, 9/7/2012 from Sunnyvale CA USA Vixen VC200L+Reducer and EOS Rebel T3（EOS KISS X50) self modded　(IR/UV filter removed and IDAS LPS-P2 is in the camera) The scope was aligned and controlled by EQMOD, guided with a self-modified TASCO scope and Meade DSP PRO II color CCD camera. ISO3200、exposure 90 seconds per frame Light 50, dark 40 and flat 20 frames, are stacked with DeepSkyStacker, post processed with Photoshop CS5 and Noise Ninja NGC 6946(also known as the Fireworks Galaxy, Arp 29, and Caldwell 12), is an intermediate spiral galaxy about 65 million light-years away, in the constellations Cepheus and Cygnus. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane. Nine supernovae (SN 1917A, SN 1939C, SN 1948B, SN 1968D, SN 1969P, SN 1980K, SN 2002hh, SN 2004et, and SN 2008S) have been observed in NGC 6946. – from Wikipedia 天の川円盤の上縁にあり, ケフェウス座アルファー星近く。 最も近いイーター星からは２．１度南西の空。天の川の星にちりばめられた星雲。 腕に沿っての物質密度上昇が顕著で数々の超新星誕生が観測されている。
