The Pearl Cluster (NGC 3766, Caldwell 97), in Centaurus, from my backyard, 15 km North from Sydney’s city center, on 4th June 2020.
This image compiles 30 x 180s images (1.5 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.
