Galactic core

This is a view of the core of our galaxy, roughly in the constellation Sagittarius.

 

This image was constructed from multiple 30 second exposures shot with a Nikkor 105 mm f2.8 lens at f 5.0, ISO 5000, on a D610.

 

Tracking was with an Ioptron star tracker.

 

Roughly 10 frames per field of view were stacked to reduce noise, then stitched to cover a wider field. This image is a small section of a larger project that I'm working on to create a large high resolution panorama of the central part of the milky way.

 

I've learnt a lot about processing astro images, but I think I still have a great deal to learn.
