Decided that I would really test out the new EOS1000D with long exposures to see if it could handle the noise and the amp glow that the EOS350D had.
So I picked out a galaxy that was new to me, NGC 6946 a spiral galaxy.
NGC 6946, also known as the "Fireworks Galaxy", is an intermediate spiral galaxy about 10 million light-years away, on the border between the constellations Cepheus and Cygnus. It was discovered by William Herschel on September 9, 1798. 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.
I targeted it with the Skywatcher ED120 900mm F7,5 refractor and used the Baader modded EOS1000D as a prime lens.
All mounted on EQ6 Pro with ED80 and QHY5 as guide.
I started with 8m subs, the absolute max for the 350D and quickly moved to 15min subs at ISO800
The Astronomik CLS clip LP filter is really good on this dslr and i reckon i could easily have got more than 15min subs.
Anyway, here she is 7 hours of NGC 6946 made up of 15min subs at ISO800 (Close to 100% crop as well)
