Today's moon
Nikon 1V3, Nikkor 200-500 + TC14e II + FT1, handheld, no stacking, already improved
The 1V3 is a neat little camera, almost the resolution as D500 and D5, has an electronic viewfinder and allows for a burst capture of up to 60 fps (1/2 second)
1J5 has the same resolution as D5 and D500: 5588x3712 px. But no EVF, so I did a little modding and I was able to attach a chimney finder to the LCD screen, and voilà: now my 1J5 has an EVF!
