Description

This image of the Trifid and Lagoon Nebulae is a 3 frame panorama, with an integration time for each frame of approximately 6 hours. Optical alignment issues have resulted in some odd star shapes - so I have reduced star sizes with Pixinsight's Morphological Transformation process before a 50% resize of the entire merged mosaic.
