alan potts Posted September 6, 2019 Share Posted September 6, 2019 Superb image and another commitment to data, 25 hours could be more than I did all August and every night was clear, though time out for the Moon. Not an easy target I am sure. Alan Link to comment Share on other sites More sharing options...
JamesF Posted September 6, 2019 Share Posted September 6, 2019 What an odd-looking PN. Looks like you'd need a fairly long test exposure just to be sure you had it in the frame. Well done for capturing it. James Link to comment Share on other sites More sharing options...
ollypenrice Posted September 7, 2019 Share Posted September 7, 2019 Faint? By Gad, then I do believe you've got it!!! A splendidly bold rendition. Olly Link to comment Share on other sites More sharing options...
pietervdv Posted September 7, 2019 Share Posted September 7, 2019 Very nice! There is no o3 component in the planetary nebula? Only h-alfa? Regards, Pieter Link to comment Share on other sites More sharing options...

Regards, Pieter There is a tiny amount of featureless O3 - but it is so little it wasn't worth including it. Link to comment Share on other sites More sharing options...
