Ze Prawn!

[Addos]

Milky Way season is back again!

Ze Prawn Nebula - also known as IC 4628 is an emission nebula located in the Sagittarius Arm of the Milky Way, around 6,000 light-years from Earth in the constellation Scorpius.

S,H, and O blended with some PIP functions for a 'sort of' natural palette Synthetic Lum from Sii and Ha.

That’s actually outstanding. Really nice shot and beautiful processing.

And gosh those stars are nice and tight!

lovely image Adam. the colour blending worked well - agree it has a naturalness about it.

[pkinchington]

Wonderful image!

One of the best Prawns I've seen Adam - beautifully done. :thumbsup:

[Addos]

thanks again guys!

re the star shapes - must concede that did require a touch of work. triplet and the little 4/3 sensor help alot, and the eq6 giving me really good guiding numbers (from memory this set averaged 0.5-0.7" error) did most of the work, but a low cost 7nm Oiii filter in a bortle 6 did leave a noticeable difference to the size of the Ha stars.

Futsed around for about an hour trying to reduce the Oii stars with unsatisfactory results. Ended up just pulling out the Ha stars, blowing them up to match the Oiii star sizes and then combining.
this took care of a little bit of the soft edges on the larger, brighter Oiii stars, though I'm sure a few have noticed there is still a slightly blue 'aura' left in some the of the larger stars. The CBD is also south of my location so any target around SCP does result in a fair bit of background glow in the Oiii. I'm using this as justification to stick my hand in my pocket for a 3nm Oiii filter :)

anyway, thanks again for the very kind comments. all this rain the last 6 months did leave me with much more time to learn and play with processing techniques, so silver lining? also take much inspiration from some of the works already posted here, so thanks for that as well!

HUGE congrats on the IOTD award, Adam!!

[Nikolas]

Got an IOTD award on astrobin nice work!

[gregbradley]

You nailed that one Adam.

Greg.

I dont understand why you futsed with the stars. OIII stars are always bigger than Ha in NB (even with 3nm OIII), and anyway star colour is irrelevant in NB. Why didnt you just go with Ha stars only (as white) given they are smaller?. If you want proper star colour then do some short RGB exposures, extract the stars and insert, either as is, or as a colour channel for the Ha stars as lum.

[AdamJL]

I've done the RGB star thing on NB data, and could never get it to look right.

[Addos]

Hi Fred

Futsing around with my data is what I do :P I had actually intended to grab some RGB for stars but clouds rolled in so I just worked with what I had :)

Next project I'll make sure I grab some RGB data too.

Cheers!
Adam

Thanks Adam, Nik, Greg, Steve, Mike and Stephane, and everyone thats been so generous with their comments! Huge surprise! I can't quite believe 15 months ago I was staring at my first star tracker and DSLR and wondering WTF with it all :P

Learned so much from these forums and youtube contributors. Its really amazing that we share so much info in the astrophotography community - I look forward to learning lots lots more!
