NGC 7000 Bi-Colour - Re-Process

Recommended Posts

I thought i'd revisit this one, as i was never truly sure abut the processing originally. 

So with this one, i sought to improve the stars (they're a big improvement) but also bring out more of the dark nebulosity. Did i go too far though?! Looking at it again today i think i may have. 🤔

Details:

Ha: 7 x 480s, 6 x 1200, 13 x 1200 (a little over 7 Hrs)

OIII: 9 x 1200s (3 Hrs)

RGB (with IDAS-D1 filter): 20 x 60s

The usual Flats & Bias, stacked in APP and processed in PS. 

Gear used: Nikon D5300 (modded); SW 80ED (522mm FL); HEQ5-Pro; SGPro and PHD2. 

The original version can be seen on the Astrobin link.

C&C welcome and clear skies folks!

ps - At the moment this is still at 100%, but i'll probably end up down-sampling it to about 50%. I don't think it can hold up to 100% tbh. 

 

Edit - Here's the new, now much more toned-down, version. It's a clear improvement, so i'll have to keep reminding myself not to try and go for big & bright, when subdued nearly always ends up looking better!

Original, nasty over-bright version:

Looks great to me!

Thanks David. 

I wanted to see how far I could push the  brightness range, so I pushed it quite hard.

Nice! I've tried that region in Ha but now you've got me wanting to point an OIII at it too.

Thanks Rick.

There's tonnes of Oiii in the NAN so go for it 😎

Very nice version of this large target, it may be a bit too big for me to have a go at it, I was looking at it last night while sitting at the scope, couldn't see mind, but knew it was there.

Thanks Alan.

I've done so little actual observing since I took up AP a couple of years ago - I really need to get back into it!

I actually managed some subs this weekend on this also. 9 x 900s ha on my WO GT71. Almost identical FOV and framing as you have! It surprised my how big it is.

It is indeed big Alan. Although i actually now wish i'd framed it in Landscape, then i might have got the Pelican in the frame too.

Came back and took another look at this and, yep, saw immediately that it was waaay too bright. I know i was intentionally trying to go for bright and bold, but even then it was still way too much.

New and vastly improved version now in the OP. 

Thankfully i had the image saved with the Lum, Colour, and Stars all in their own layers in PS, so it was easy to fix without messing with other elements.

      Having upgraded from canon 1000D to Nikon D5300  how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens ,  do you use in manual mode  and look at histogram ? .

      Hello!
       
      I'm from Hungary. This is my first post. I am glad to be here.
      Recently I'm trying to sketch some deep-sky objects. I've made this observation yesterday. Cygnus was near to the zenith and the sky was pretty dark.
       

      NGC 7000 is one of my favourite target. I like to observe it with any telescopes, especially with RFTs and with UHC filter.
      Please excuse my language errors.

      Hi guys
      First things first, apologies for posting this one out of season. A combination of no astro dark, crappy weather, and being busy at work has meant that there's no imaging getting done at all these days. So, i've had to turn to old data to re-process, and this data set was an obvious candidate as i was never happy with how it came out originally. And looking back on it now with fresh eyes, boy did it need it! 
      Nikon D5300, SW 80ED, HEQ5-Pro. 
      3 x 1200s, 2 x 1380s, and 4 x 1500s of Ha
      9 x 1200s of Oiii. 
      11 x 480s with an IDAS-D1, for RGB stars only
      7 Hrs 54 Mins in Total. 

      Stacked in APP and processed in PS. 
      Combined as SHO (using a 70/30 blend of Ha/Oiii for the Sii). 
      The main differences this time were, using Starnet++ to create the starless versions, using more Ha in the synthesized Sii (70% instead of 50% last time), but mostly the improvement has come from toning down the stretch a lot (ok, a heck of a lot!) before making the colour map for the tone-mapping. From then on it was immediately apparent that i'd made a massive boo-boo first time round 🙈
      I've included a 1080p rotated crop too, as i quite liked the framing.
      Feels like ages since i last did any NB imaging. I almost forgot how much i enjoy it! 🙂 


       
       
      And rather embarrassingly, here's the original. Try not to laugh too hard! 😂 😂 😂

      Back in early Feb I tried imaging Markarian's Chain, but after 2 subs I encountered guiding issues (a first for me) so had to give up. 
      So just for kicks and giggles, I decided to process them! ? 
      So this is 2 x 10mins. With the D5300, 80ED and HEQ5-Pro. 'Stacked' (if it's even right to use that term!) in APP, and processed in PS. Then reduced to 75% for posting. 
      Why oh why oh why..... I honestly don't even know myself ?

      Hi guys
      I'm breaking the cardinal rule here of posting late at night, right after finishing PP, so let's see what sense the dawn brings! ? 
      I shot this in the early hrs of 29th of March. There was no moon present (i think!) and conditions were pretty good, AFAIK. 
      This is 28 x 360s, so about 2.75 hrs in total. Taken as usual with the D5300, IDAS-D1, and SW 80ED. 
      APP used for stacking and gradient reduction, everything else done in PS. 
      Would have liked twice, or 3 times, the data, but it's just not happening, so i've just decided to process what i've got. 
      Thanks for looking, and all CC welcome as always ?
