The Pearl Cluster from Sydney

The Pearl Cluster from Sydney

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.

Full resolution image in my Flickr.
