Astrophotography M45 - Pleiades

Post image

My attempt on the Pleiades: Untracked, shot with a Sony A7IV and the Sigma 24-70 mm F/2.8 (exposures are shot with 70 mm).

This is a stack of 1250 3.2-second exposures at f/2.8. I've only used Siril for processing (calibration -> background removal -> stacking -> stretch -> green noise removal & color calibration).

I had difficulties processing the amount of pictures, as one set of the 1250 pictures was something between 400 and 500 GB, and due to how Siril works, I always had around 1 TB of data in my Process folder. Because of this, I had to have it on my HDD, which made the whole processing quite slow.

I'm still rather new in this hobby, but I really enjoy it and want to get a tracker, as this is probably the logical next step.
