Lagoon Nebula

[bugeater (Marty)]

Here's the next thing I've spent processing from last weekend at LMDSS.
It's M8 aka the Lagoon Nebula.

33 x 300 second subs. Only subtracted darks. My usual setup with a 200mm f5 Skywatcher newt, Canon 700D (unmodified), QHY5LII guidecam running through PHD2. I got up about 3am to set this one up and it ran until the sun came up.

Processing is entirely PixInsight. Main processes have been a deconvolution, TGVdenoise, and some messing with curves and the histogram. For one of the two images I ran HDRMultiscaleTransform, which had interesting results, but I'm not sure which version I like best. I was messing with HDRMT before stretching the data and gave up because I couldn't get rid of artifacts, but accidentally ran it after stretching and it worked great.

Proper versions here:
HDR: http://astrob.in/full/181914/0/
non-HDR: http://astrob.in/full/181916/0/

They're great images Marty. My preference is for the image with more detail (181914/0) in the centre. Last weekend was good in Melbourne and obviously fantastic at LMDSS. (I must get there sometime!) Your result was well worth getting out of bed at that hour.

Some nice detail in number 2.

Hi Marty,

Both are great images, but I'm with Robert and Kevin in saying 181914/0 is more to my liking. The centre of the other image is a little blown out and you can't see the detail.

yep second one for me you can see the structure better, whereas in no.1 its glared out. I actually really like the unmodified dslr lagoons, much more blue comes through, the magenta is almost overpowering in other versions.

Nice job, but I wholeheartedly agree that unmoddeds look better.
