Re: Bubble Nebula

Here is the Bubble Nebula done 2 ways. All 900s subs. 13-Ha, 14-OIII, 11-SII. 15 Darks and 15 Flats each. The first is HSO and the second one is SHO Hubble palette.

Which do you like better so far?

I did a print of each off of the Tiff file and it is really nice.

Re: Bubble Nebula

Very nice i like the second one a bit better but that is just a matter of preference. Great Job!

Re: Bubble Nebula

Thanks Zach. These are just 10min processes in PS to see what I have. I have the 3 subs in PI now and got them rgb combined and aligned, now just need to do all the processing. Hoping to get one half as good as yours and If all goes well in PI hope to have a pic done by at least the 4th of July :16:

Re: Bubble Nebula

What if you blended BOTH?

I love the first red, but, I really like the orange bubble with it's teal green too. Make layer mask and blend with a gaussian blur. Personally, I'm not in it for the science. For me I like creative colorful photos!

Either way, still a great job Rick!

Re: Bubble Nebula

I got them on my flats as well. I had to cut the ADU down to 20K to make them go away. The banding on the astrodon's is so bad that if you over expose your flats the bands will burn into the image and actually print them out on your image. Re shoot your flats at a lower ADU until you see them disappear.

Re: Bubble Nebula

Doug,

I'm trying to understand what the formula you have up there is. You should be able to take your Ha image and put it into the Red box and the OIII image and put it into the blue box. For the green all you are doing is blending the Ha and the OIII to create the green. Whatever amount of red you want in it will be determined by the number you assign in the parenthesis. .09 is a good starting ground. I've used as much as .15 on some of the images depending on the color that came out. What I usually do is do several different ones. I'll do one with .03 then .05, .09, .12, and on and on if I need to. After that I just pick the one that I like best and close out the other images.

I am pretty sure that if you put a check mark in the box under the math equation it will open a screen that will allow you to scroll to the images you want to use on the right side of the box.

Re: Bubble Nebula

Not sure what you mean? I have HSO = hA-sII-OIII and SHO which is sii- Ha-oiii respectivly in the r-g-b channels. I have not done the bi-color with pixel math yet.

Re: Bubble Nebula

Sean,

My notes tell me you provided this formula for star colors...

Re: Bubble Nebula

I don't think I posted those equations. I would guess Jeff or Mike might have posted those.
