Captured NGC 6357 Lobster Nebula for the first time at my South Coast Obs on Monday night as conditions were excellent, little or no wind , no dew , low humidity , good seeing and transparency in Bortle 3/4
My set up just squeezed in the main body of the lobster in the FOV but a wider field would be more interesting

Managed 4 hours ( 3 minute subs ) of good data with the 8” f5 newt and my 2600MC using the L Extreme NB filter, camera cooled to -10C
Guiding in PHD2 was really tight for my low end mount ( EQ6-R pro ) at 0.70 arc sec total error most of the night ( Dec around 0.50 and Ra around 0.65 or thereabouts with a few random tiny spikes in Ra )

Data stacked in DSS
Processed in Startools V1.7 ( OSC Linear data set )

Synthetic Luminance version
Colour version RGB

Comments welcome
Thanks

Great guiding performance there. And with a result to match. Nice work, Martin. This isn’t an easy target

OK M, here's a proposition...

I'll catch the lobster, and you can cook it!

Thanks Adam
Yes I needed plenty of data to bring out the fine detail, my 8” is a good all round scope for most objects
Conditions were great which helps

Peter,
Thanks mate
Strangely enough lobster is not my favourite seafood , a nice piece of flatty will do me , still happy to snag the celestial variety
Cheers

Nice result there Marin.

It is such an intricate and fascinating nebula, almost a bit of where's Wally feel, so many little complex details :thumbsup:

Thanks Mike,
Appreciate it
A fun object to image
Bit of bad weather heading down my way now so locked up the Obs for the next 3 or 4 days , hopefully clearing by Tuesday / Wednesday next week
