Couldn't think of anything better than this classic trio for first light for my RedCat51.

Pictured are the the Lagoon Nebula (M8), the Trifid Nebula (M20) and the fainter NGC 6559. Imaged in narrowband with the Optolong L-enhance filter. The data was collected over 10 hours on multiple days - with the first 3 hours under Bortle class 8 suburban skies (Brisbane) and the remaining 7 hours under Bortle class 1/2 skies on K'Gari / Fraser Island. (You've got to love work field trips in winter!)
