M20- Trifid Nebula

Hi All,

This is a first light with my QHY9-Mono CCD. Taken from my backyard suburban Melbourne on the 17/05/2015. I think it turned out ok, but my stars need better processing

Any comments or feedback/tips much appreciated.

Details are: 15x300sec Lum, 15x180sec RGB binned 2x2 on a QHY9S mono. Guided with a QHY5L-II and orion 50mm guidescope. All on a Neq6Pro mount with Explore scientific 127ED.

Repro version here: http://www.astrobin.com/full/182412/0/

Thanks for looking, Clear skies!

Lovely Goran. What does it look like if you throttle back the overall brightness?

Hi Robert,
Yes i noticed the brightness as soon as i saw it on another computer!
I usually process on my iMac and the contrast and colour is much different. I have been advised in the past to use sRGB instead of AdobeRGB but I keep forgetting!!
Anyway I have attached an edit, hope it looks better.
Goran.

Thanks Martin,
Yes I did try one with the Ha, but it only reall shows up the emission part, and i wanted to get some Lum for the whole thing so that I could get a complete image to check the new CCD But yes, i will add Ha next time out.

I wasn't game to say anything negative, as everyone was obviously happy with your image, but I can now say that I am happy that you have quietened that bright copper/ bronzish background colour right down,
however, for my taste, I think the colour saturation is now just slightly overdone. Nice job anyway.

Thanks Ray,

Yeah I fixed it once I noticed it on another computer, actually it was terrible.
I can see where you are coming from regarding the saturation. I have made some changes to this but I won't upload any more to this thread.

Greqt images Goran. I'd be happy with either of those last 2. As Ray says, it is a matter of taste.

(with camera soaking up photons outside - clear in Melbourne! Encroyable!

I took the time to look at your latest image; that's better.

Possibly still a little overly-contrasted for my tastes (I probably under cook mine to be honest) but really nice colour and saturation in your final image.

Good job Goran. You have a good set of data there, so it will worth your while to have another crack at the processing when ever you are in the mood. Practice makes perfect.

One thing I have done is to look for a good image of the same target by someone else, and then try to replicate it with my own data. I have learnt a lot this way :-)

Thanks James,

Yes I have seen lots lately, I think somewhere in the middle of my original and my final would have been best, but, I think I'll wait until I can get some more data for it, perhaps some ha for the emission area and the fainter nebulosity which I think I processed out

excellent start to the Trifid Season Goran
You really have dug out the detail with your second image and tamed the background well.
The colour vibrance is a little on the high side but does make the nebulosity pop out well.

Hi Goran, nice image! Possibly just a wee bit too saturated for my tastes in the repro - I quite like the gentler nebula colours in the first image, but the overall effect of the repro is probably better.
