Hi,
I have been gathering data for a long time on this one and finally decided
enough was enough. I have 33 hours of total time invested in this one. I
like planetary nebulas in narrowband because they are usually rich in blue
(OIII). This one is no exception. I have some RGB data from a previous
image, but it has a different FOV than this image so I will have to crop it
to get the RGB stars in. I may do this later.
