Considering how cold is was last night, I thought this was an appropriate target! I love planetary nebulas, and The Eskimo Nebula is one which gets so little attention, mainly I think because you need so many subs to get any detail out of the little blighter. This is 600 - yes 600 - frames of 30 seconds at ISO800. And what's more the 'scope was unguided, which is pretty amazing really.
There's evidence of some clumping the nebula which I think some narrowband filters would help bring to the fore, particularly around the edges of the darker, outer donut of dust and gas. I'm really pleased that I managed to get some detail in there - I've been imaging this thing for years and never been able to tease this much out of it! At 2,870 light-years away, this must be quite a large nebula up-close, and indeed Hubble images using narrowband filtering shows significant and complex structure.
Personally, I think this should be a "benchmark" object for any good telescope, or indeed imaging train. Even a modest tube will reveal that it's not just a star, and my mid-range 8" has been able to get some good detail. I'm upgrading the imaging systems over the course of the next few months, and with a little luck I'll be able to highlight the improvements using this very object!
