Details:
I had prepared myself both with the Ha filter and with the Herchell Prisma white light filter, both combined with the Televue Genesis refractor. However the adverse weather conditions did not allow me to use the filters: the diffused light of the veiling of the sky did not allow the correct focusing and sometimes the solar disk appeared too dark. It follows that I was forced to abandon the use of the telescope and try to shoot with a Canon EF 300mm f / 4 lens without filters. In doing so I managed to focus properly and also expose on the solar disk, which was filtered through the clouds.
The site where I stationed myself is located under the approach path of Fiumicino airport, but the standard procedures begin in the North-East with respect to the path of the Sun. However, today, the misfortune of bad weather has caused the controllers to have vectors sea arrivals right in the direction of the Solar disk. I noticed that there was a dense approach sequence that passed under the Sun, but that the planes went higher and higher as they approached the Sun. This happens because in the approaches the aircraft in the queue are authorized at higher altitudes than the first. Considering this rule (my job is Air Traffic Controller), I waited until an aircraft arrived at the same apparent height of the Sun to take a pass near the disk. At this point, luck also allowed the clouds to thin out as much as they needed to focus on transit too.
In the elaboration I assigned a false color to the solar disk because in reality it was whitish. Time of shooting: 14:44, Canon Eos 1DxMk2+Canon EF300 f/4L
