The Trifid Nebula from Sydney

The Trifid Nebula, M 20, from my backyard, 15 km North from Sydney’s city center, on 15th June 2020.

This image compiles 40 x 300s images (3.3 hours total integration time) obtained with my Skywatcher Black Diamond 80, an Orion X0.8 focal reducer (f/6), the ZWO ASI178MC camera and an OPTOLONG L-Pro filter.

I used the ZWO ASIAir to control the camera, the mount (Skywatcher AZ-EQ6) and the guiding system (ASI120MM + Orion 50mm finderscope).

Flats and darks included. Data processed with Siril software. Color / saturation / levels / contrast / smart sharpen with Photoshop.

Full resolution image in my Flickr.
