Image taken on 16 April 2016 from Mersing, Malaysia.

Even though the sky is not spectacular on that night, I managed to grab some RGB data to produce this image. RGB image with four 6-minutes subs each filter. Located in the constellation of Sagittarius, the Trifid nebula is a beautiful combination of red emission nebula, blue reflection nebula, open star cluster and dark nebula. Further to the lower left of image is the open star cluster M21.
