some things just need to be in B&W. I do have multiple hours of SII and OIII data on this 2 panel mosaic, but this Ha data is just worth looking at all on its own.
I have completed the SHO version now, for a total exposure time across the two panels of 26 hours. The colour version is however cropped a little from the Ha version I posted earlier.
David - I am sure there must be a planetary nebula in there somewhere but I havent found it!
