Title: WIP - JellyFish Neb - IC443
Post by: JohnP on Jan 04, 2009, 17:51:37
This is an interesting looking Neb. I grabbed this Friday night - it's my first in about 4months & it actually took me longer setting all my equip up & getting it working than it did to get the subs... :-(

Mark - My stuff was all still packed away from when we went to Riberac...

Anyway - Atik 16ic + ZS66 & 0.8X flattener. Ha - 24X300secs

Needs longer & more subs to reduce noise (or a Hyperstar... :-) ) but it's a start..

Cheers,  John

Fantastic image John, I had a go at this last week but wasn't able to resolve much apart from the "bell" of the jellyfish, great job!

Cheers Chris, Paul, Daniel...

Chris not sure if Olly has ever done this but I would say it would be superb from Les Granges - something along the lines of the Pacman...

Daniel - Hopefully I can add more - I really need to try & get to 10min subs...

Cheers,  John

That's really good John and it's great to see you out imaging again!  I also did the Jellyfish but on 30th - it ended up looking really noisy due to the conditions.

Must try harder Robert!

That's a very nice image John.  It's a difficult target.

Good to see you out again!

Quick update - I added another 45mins (9X300secs) of Ha data before the clouds came last Saturday. So image now comprises 33X5mins & it still needs a lot more:-(

The 45mins hasn't really made any difference (at least in my eyes). I plan on giving this one more session the next clear, moonless night..

Cheers,  John

I think it is a good image, John. I have always fancied this one.

Thks still need some more frames though to reduce noise. It would look glorious with your 314L through the ZS66 - you'd get it all in (unlike me).
