This is a work in progress I only managed to get around 42 mins of data before the clouds moved in.
It really needs a lot more data so I hope to be able to add to it soon.
I think I am pushing close to the limit of my setup and skills with the alt/az mount with no guiding setup ,
I am hoping to push this one to 2 hours or more of data and see what results.
Eta Carinae Nebula NGC 3372
100 x 25sec subs at iso 1600, darks and bias (42mins total)
12' LX200 (alt/az setup, no guiding)
Sony Nex-3 DSLR
Stacked in DSS
Processed in GIMP
Slightly Higher resolution here ( 44% reduced and JPG compressed to 1.96MB)
