NGC7000 Cygnus Wall
NGC7000 Cygnus Wall by Dean Ashton
M3 – NGC5272
5hrs of total exposure using 10min subs. This was to get the very faint stars at the far periphery as well as the brighter centre that would require lower exposure. I used an extended full-well-depth mode on the camera from this to give a full well depth of 75,000e to prevent the core blowing out in the 600s exposures. by Dean Ashton
M33 by Dean Ashton
M33 with Ha and RGB combined. Specifically 11hr20m (68x600s) of RGB and 4h20m (26x600s) of Ha combined. As you see, combining the Ha makes a big difference to the image. M33 is very active in star formation. THe Ha is also providing greater resolution of some of the larger nebula in M33 with structure in NGC604 becoming clear.
