Have a visit in my portfolio

Wednesday, January 15, 2020


I was imaging at December 31. Since my observatory locates at centrum of the city, there was lots of fireworks going on around. One of my 20 min sub frames captured a big one! Image was taken with a Tokina 300mm f2.8 camera lens, 5 nm H-alpha filter and Apogee Alta U16 astronomical camera.
