First Narrowband

Post by gardenfish » Fri Jan 13, 2017 1:55 pm

I tried the flame the other night between clouds. I only got 3 ea of Ha and OIII. Stacked inn DSS and followed a video that put Ha-red, OIII -blue and Ha/OIII combined for green. This is what I got in PS.

I do not think there is a lot of OIII in this object but was wondering if with proper processing if the color could change a little. This was my first attempt at a bi color image in rgb so I am not totally dissatisfied but wondering if anyone could try it in PI and show me what could be done. I have a link below to the 2 subs. ... 9lAHa?dl=0" onclick=";return false;

Verrry Nice Rick!

Narrowband, my first thought was Hubble Pallet:
SII = Red
Ha = Green
OIII = Blue

Nice surprise because this looks like a traditional LRGB shot.

BTW, if you do decide to try Hubble Pallet, I found this to very helpful:" onclick=";return false;

Congratulations. Welcome to the dark, dark side...narrowband imaging. If your anything like me when I started, I tried getting that first tri-color image asap. Consider slowing down a bit, sticking with the Ha filter grabbing many many hours of data on that filter. Use ONLY the good, in focus, hi SNR subs for stacking. And then learn a minimal process for Ha that is meant to be displayed in Black and White. Now that you have the rig, you will find, if you haven't already, a new appreciation for B&W. You could start to focus on bringing out fine details and keeping background subdued. You may obsess on star shapes, or field flatness. There is a boatload of skills that simply shooting H-alpha will teach you. Then when you got that nailed down, add the Oiii for a BiColor. Look at RV's Bicolor skills. The great thing about AP is that you will use this years Ha data on any given target with next years Oiii and Sii. That is IF you plate solve to get your framing perfect.

Once again great job, keep them coming!
