I took my travel scope to Lapland to my home place, which I hadn't visited in 10 years. The sky there was beautiful with the Milky Way visible with the naked eye. I had a problem with the declination motor breaking and the filter wheel not wheeling, so I shrugged and shot luminance. Now after returning home I got the colors for this.
