I observed pass of the ISS and Progress MS-16 spacecraft with Pirs module at 12:41 UT on July 26, 2021, from Yuzhno-Morskoy, Primorsky Krai, Russia. I managed to take this photo (in a small gap of large clouds) and I observed them with the naked eye. My estimates: it was +3 mag. at distance about 0.5 deg. before ISS.
I used my camera Canon EOS 60D (with broken display: I used optical viewfinder) on unstable stand (so tracks are wavy in the photo): ISO-2000, 3.2 sec., 75mm, f/5.6.
