Thanks Les, Phil, Coen! Must admit, objects like NGC 1535 are the only ones that give me a twinge of aperture fever (or more correctly 'aperture envy'!), and thoughts go to one dark night at Snake Valley, cruising a number of small PNs with tnott's 16"! The rest of the time I'm happy with what I've got - there's just so much out there!
Thanks for your wonderful description of 1535 Les, and hope you get to eyeball it again soon!
Cheers -
