Milky Way Mosaic

This a portrait-mode crop from a mosaic that used a total of 11 panels. (Given the cropping some of those frames are seen only partially here.) The mosaic was constructed using Microsoft's Image Composite Editor (ICE). The camera was mounted directly on a tripod, with the camera's Astrotracer feature providing tracking internally. Even though this was shot in the country, there was a considerable amount of light pollution on the horizon from a mid-size city roughly 25km SSE. This is the best I could do to eliminate it using a program called Sequator. Further improvement will require a more sophisticated gradient-reduction tool.

_Imager: Pentax K-3II DSLR (APS-C). _Lens: SMC Pentax-M 28mm f/2.8 @ f/4 _Exposure: 120 seconds x 11 panels @ ISO 800. _Tracking: Astrotracer (built in) _Date: August 11, 2018. _Location: Near Conestoga Lake, Ontario, Canada. _Sky Conditions: Bortle ~3.5, average transparency.
