Panorama from the terrace of the Kopitoto TV Tower, which is not publicly accessible. Special thanks to the management and staff of the facility for access, patience and understanding!
The distance to the center of Sofia is 10 km (6 miles), so clear weather and low sun were key to making this quality gigapixel panorama. In this case the panorama was taken shortly before sunset, so heat haze was at a minimum. As a result of this, you can clearly see the planes at Sofia Airport which is 15 kms (almost 10 miles) away. The shooting was supported by Canon Bulgaria, who provided the best possible equipment for the purpose:
mirrorless camera Canon EOS R5 and lens Canon EF 600mm f / 4L IS III USM + Extender 2x III . For whom he is not familiar: with a 1,200mm lens it is difficult to shoot even from a tripod, and in this case there was a panoramic robot + strong wind and dimming light. As you will see from the gigapixel panorama, the technique did more than brilliantly!

Thanks to the heavy tripod, the stabilized lens and sensor of the camera, as well as the stable and precise panoramic robot Roundshot VR Drive, we were able to take this big picture. The camera was controlled by a phone - Live view for focusing and shooting, and for the robot we had two options - either wi-fi connection with the phone for programming and positioning or a radio remote for moving. Full synchronization between all components was a key moment in the project implementation. The panoramic VR Drive robot had no problem moving the large optics and the camera (its load capacity is as much as 20 kilograms!). The movement it provided for our project was between 1 and 3 degrees with accuracy 0.1 degrees. The results of this professional equipment are shown on this website!
We also used custom software to even out the exposure values and colormetric values of all photos in order to create a seamless panoramic photo.
