Lagoon more time

[xelasnave]

I took some more of the Lagoon Nebula and stacked 170 at 30 seconds thru the 8 inch using the nikon camera.
No darks and played with first in photo shop and then in gimp to the point where I am not sure any more ..I probably over did better images along the way but I had to put it up and see how it turned out here downsized and ready for pointers on the colour...But I think it has more detail by reason of more frames and the second lot were in better seeing so added to things hopefully...its all practice.

Nice Alex! I do believe that yours is quite green though, as the nebula is supposed to be red from hydrogen alpha (but also a bit of green 03!)

Thru my careful imaging I was able to show more oxygen you see
I think I did have a redder version
I guess being in the bush so long I now see in green.

Thanks Leon I am happy with getting the detail for the moment..colour will always be a guess but why let that hold you back.

Thanks Kevin I though it was maybe another tweet and aim for red.

here is a short Triffy only 47 30 second frames. Had to take something whilst waiting for whatever which I did not get...I did a few of these I think this was the final attempt.

hi alex,

that definitely looks the colour of O3! i've used an O3 filter on DSLR and you pretty much have it exact!

reckon you could post a pic straight out of stacking somewhere? pre colour editing? I'm not sure if it is your stacking parameters or the image processing that is causing the difficulty with colour balance?

Cheers

Hi Russ

Here is the last stack which is some 1.5 hours from a huge stack of 30 second captures.

thats a lot of 30 second subs alex! and the date is quite good

the stack is quite nicely colour rgb colour aligned.

therefore colourwise it is probably something happening in your processing routine - all you really need to do (if you wanted some more colour vibrance that is) is drag the saturation slider across to the right somewhat, to your taste - and it should stay pretty true from a balance perspective (will work in photoshop or gimp).

cheers
