I had a couple of tries imaging Neowise a few nights ago. The best results were obtained by using my Ioptron Skytracker. I attached my Sony A57 with a Minolta 100-200mm zoom lens we've had for about 35 years!
The images are taken at 3 focal lengths, I couldn't decide which was best. All taken at ISO1600, F5.6
100mm. 26x5s
160mm. 10x15s
200mm. 15x6s
I started with the 200mm exposures when it was still slightly light, hence the shorter exposure, then the 100mm ones and finally the 160mm ones.
F = 100mm
F = 160mm
F = 200mm
