Visibility I / V
5 years ago, I photographed the Makemake dwarf planet from my home balcony.
When these domestic climates have been extremely bad again, I decided to try to see if it could get an object about 2 magnitudes dimmer than described with half the optics.
Yes, as long as you shine enough.
With a 10 minute exposure, the subject was barely visible but the other night I stacked 10 10 minute exposures and showed a little better.
The images taken every 2 hours did not show the movement of the dwarf planet but required a day difference.
Another image is a slightly rugged animation where the movement stands out.
I measured the brightness of the dwarf planet with the ASTAP program on 18.8.
This is not the object I photographed dimly , but the quasar i I photographed in 2018, whose brightness was mag 19.08, gets its honor.
