Sadr region in Cygnus 22 July 2011
The area of nebulosity around the star Sadr in Cygnus. Sadr's "formal" name is γ Cygni, or Gamma Cygni, and the area takes the name Gamma Cygni Nebula, IC 1318. The nebula immediately below Sadr is commonly known as the Butterfly Nebula. About 1500 light years away - as the crow flies :)
Nikon D70 full spectrum, 55-200 Nikkor at 200mm (cropped) , f6.3, 1600iso, Baader Neodymium filter.
27x180sec subs for a total of 1hr 21mins, unguided EQ5
Darks, flats and bias
Stacked and processed in DSS and CS5, with a little help from Noel's tools.
The new filter seems to have given me more star colour, which is nice, and the new mask seems to have kept the stars reasonably under control (by DSLR standards).
