Did a version last night, to improve the colour in the core region. Notice that especially when the highlights are bright, the colour tend to be washed out as in the previous versions. With careful control of the tonal range, and a little more central saturation, the core now looks a little better, instead of it being a little 'greyscale' like in the center.
Orion Nebula (LRGB)
Hi all!
Think this is about all. Gathered more 10 minute subs today, mostly on green and blue channels. Can't believe that the sky cleared long enough this week complete this project with only less than 2-hour permissible window period (before the object is obscured from view from the balcony). Each consecutive night, the clearing window thins as the nebula rises earlier each successive night. Tonight there was only a 1-hour permissible window period where there was no time to waste, yet again, no drift alignment was done, mount was there where it was from previous nights, quick calibration, and then data collection began. It was becoming ritualistic by now, and as more data is accumulated, the processing became easier, the colour balancing began to "click together" and "make sense" without much effort in figuring out what is overdoing, or under-doing, if there is such a word...
Total cumulative exposure time is about 4 hours total. Luminance no change, taken from old data from mersing. the rest of the colour channels are all taken from spore at the balcony, ranging from 5 min subs on average nights, to 10 min subs on better nights (like tonight and two nights back). tonight was spent obtaining more green and blue data channels, as such the colours are almost there! (hopefully it is!) And the luminance from mersing is not so overbearing by now, as compared to earlier attempts posted in this same thread.
think i will stop here, and end this project for now (until the opportunity to take colour data from mersing).
here goes, final! adios! getting tired of this image already! ciao! lol....
