This Summer nebula brings to mind 1960's school days - and first views with a friend's 4inch 'scope. I took a lot of photos. Yet this 2010 pencil sketch seems more natural - why? The bright stars have been tweaked with software to suggest their dazzling presence. Specs: 10in. F5. H-beta filter, at an urban site.

Planetary nebulae are elusive targets - and can be more so if sited amid bright stars. This one adorns star cluster M46 (NGC2438). Often a narrow-field e.p. helps reduce competing glare. This is a pencil sketch but the stars have been enhanced to show their true sparkle: its a beautiful cluster, but we see just a small part here. The nebula is a chance alignment and the 'central' star is unrelated to it.
