Description

Now, I know NGC2438 does not belong to open cluster M46 it just happen to be in the same line of sight. Still it makes for a poetic one-line description. It is also the lowest altitude I have ever imaged PNs from Lincoln (UK), sitting, as it is, at declination -14.73 degrees and realistically I don't think I can lower the bore of my scope any further down. I didn't have it in me to go full scale and time is of the essence when you looking through this much air so I went binning so that the whole affair was over in 24 minutes, no guiding either.
