This is the first light of my brand new iOptron SkyTracker. Just a single raw 5-min exposure on a standard Canon lens at 55mm f/5.6, no calibration file. A little bit of Photoshop for basic enhancement.

The objective was to check the tracking quality after a reasonable polar alignment. The result is very satisfactory.
