M8 NGC6523 Lagoon Nebula and Cluster, M20 NGC6514 Trifid Nebula in Scorpius - 17/6/2017 (Processed Stack)

Imaged at Perth Observatory

Second light in darker skies for 0.6x Long Perng Reducer with recently acquired Skywatcher ED80 reducing it to f/4.5 FL=360mm.

The corners also show notable flare in the star mages, so whilst the extra field is appreciated from the 0.6X Focal reducer, flatness is lost compared to .85X or .8X options available.

Compare to 3/6/2017 'flat' version from suburban skies. Also see cropped version of this image.
