A little more than two years ago I had already photographed the Pinwheel galaxy. Last night I photographed it again with the Nikkor 300mm f/4 PF and the Fuji X-T3 on the iOptron mount. Again, the positioning was not easy and finally the galaxy itself landed in the lower right quarter of the sensor. This needs more practice…

M101 – Pinwheel Galaxy

Besides, 300mm on a crop camera is quite short.
