Lagoon in LRGB + HA

[DavidNg (David)]

Hi,

My old imaging computer crashed, it took me over a month to setup and fine tuned the new system.

This is the link to my test image of the popular Lagoon nebula. It consists of L: 8x15m RGB 2x15m each and HA: 1x20min, all 1x1 bin. This is also my first colored image, processing in LRGB is a little overwhelming for my head. Once the system is in working order I hope to get more RBG data of this nebula.

My equipment: 6" refractor, cooled CCD, guided with a guidescope. Captured with Maxlm. Processed with PixInsight and Photoshop.

Thanks for looking.

that looks cool, a fine first effort, almost 3d-ish with some whisps of gas.
Is the core of the nebula a little blown out?

Thanks Josh, PixInsight has some sort of core brightness reduction, which I still dont know how to apply.

There's some really good data in there. There's two algorithms in pixinsight you might want to try, one is the local contrast equalization, or alternatively the HDR wavelet routine. In the scripts section there's also a dark structure enhance algorithm that can be effective too.
Just start with the default parameters, and experiment with the various knobs one at a time!
Cheers,
Andrew.

Thanks Andrew, I have been busy collecting more Ha data last few nights, once integrated data available I will do as your advice.

Thanks Andrew for your advice. I've managed to somewhat reduced the core brightness using HDR Wavelet without starmask. Some folks in Youtube suggested starmask in PixInsight when using HDRWavelet to protect the stars, I tried for many hours, yet to understand exactly whats I got to do. I also added in another 5x20min of Ha data.
