Salam,
I was fortunate to first visit Istanbul in 2002, and since been back many times over the years. By the grace of God I was once again able to visit the city in December 2021 and discover new places which I was previously unaware of.
One such place was the Kalenderhane Mosque which I had seen many times on my visit a few years back but had not taken the time to investigate. Some brief information can be found in the video below. I have also uploaded my attempt at taking a panorama picture with my smartphone as the video perhaps does not do it full justice.
