Let's Kick Off Nebula Season! M16 The Eagle Nebula in Foraxx without GHS!

- Kicking off nebula season with the very famous M16 Eagle Nebula. This is an object I originally imaged over a decade ago when I first got my Nexstar C8 with a DSLR and never really went back to do it justice. After chasing very dim nebula I was shocked at the high dynamic range this actually presented. I'm presenting mine in a Foraxx palette. I utilized my NB to RGB star script for the stars and did my initial channel stretching with my Statistical Stretch script, I didnt have to use GHS at all during the entire processing!!
There are some really less known tiny objects around the field of view as well. Multiple Planetary Nebula / Emission Objects. A relatively bright Emission Line Star with the gas cloud interacting with it. Many dark fingers of dark dust columns where new stars are getting born as well.

I will say my scripts did very well for this image. Didn't have to use GHS even once :)
I did re add my Ha as a Luminance into the image for a revision 2, as the Foraxx Palette Utility script tends to blow out very bright areas. Please take a look!
Frank, thanks for the ‘kick-off!’ Nothing like comparing past results with current accomplishments (I have a red blob image I took with the Revolution Imager!!!). Your scripts allow us to leap-frog into more sophisticated post-processing. Can’t wait to see what you come up with next.
Spectacular image, it must be very satisfying to see it compared to your earlier version. Thanks for uploading.
Thanks for the informative video and love the Foraxx . Nicely imaged and processed
Onwards and upwards to 2,000 subscribers. 🎉 Hopefully that will be a lot faster than the first thousand. Thanks for the fantastic things you're doing and sharing Franklin.

Quite nice.
I recently photographed my first nebula, the North American Nebula. Used a Bresser 102/460 with a x0.8 generic reducer (f/3.6) and an SvBony dual band filter on my Star Adventurer GTi on Sharp Cap pro for 60 minutes worth of 8 second exposures. Came out pretty with billowing clouds of glowing gas.
Thats great news! If you want to email me a copy I would love to see it. First nebula is always exciting!
Very nice! What settings did you use on your Ha Statistical Stretch? Thanks for the good work.
I did 0.25 with no extra curves stretch. I then had to use HDR transform to bring some more detail back to the core. I do show that in my script video as well
Got it. Thanks.
Many people with OSC cameras that already have dual narrow band filters (HA and OIII) are now purchasing the filters that offer SII and OIII or SII and Hb. Can you look into creating a script that can split then combine the channels accurately to create SHO or HSO?
Those work becuase the dual channels are widely seperated. Just a standard channel extraction and use the Red for Ha or SII and Green for OIII or Hb, whatever combo that particular filter is using. Once you have your seperated channels you can combine them in channel combination and then use my Statistical Stretch script in unlinked mode.
Also View Into Space just posted this script too. czcams.com/video/h8o0s6PFQyE/video.htmlsi=ghaVIy5FU_dBdVVQ
@@setiv2 thank you so much. I will be sure to mention you and highlight your scripts in my upcoming videos
On what scope it was captured? On astrobin it shows 120mm achromatic refractor, is it real?
It sure is real. Orion 120ST achro native f5 and I have an astrotech 0.8x reducer on it to step it down to a fast f4. I call it my secret weapon scope. I shoot with a mono camera so there isnt any real problem, especially in narrowband.
@@setiv2 did you modify it somehow? Maybe focuser? Also did you look at any parameters when choosing an achromat, or you just picked by focal length?
Before your picture I couldn't even think that narrowband + achromat actually will work, this is genius!
I got it years ago used. No real modification, just slapped an EAF on it for autofocusing. I do also offaxis guide with it for guiding instead of a guide scope. Even my Andromeda image on astrobin was done with it. All my tutorial videos are images from it too.

This shows it.
Was your dslr modded ?
Not at that time. I did get it modded and built a cooler for it too. Now I use it as IR cam for landscapes since I use my asi cameras.
@@setiv2 was the opening image taken with your un modded dslr? If so ill give a go with mine :)
No. That is my new image. I show my original old school image at time stamp 03:00
@@setiv2wow id be very happy with that image myself as a beginner. Ty for the answers, will put this on my list to try when/if its high enough
It is an easy first target. Very bright and has that wow factor. If you havent imaged it you should.
