Description

Cave Nebula in LRGB. Experimented with various star reduction techniques...still a work in progress on that front. MT with cross element structure seems to avoid dark circles around star (from the star mask and circular element). Also have better results with smaller sized structuring elements. Too much star reduction on luminance results in dark halos around combined LRGB...avoid that.
