Toscanelli more or less lived all the time in Florence.
He's called a mathematican, cosmographer and astronom.
He made observations for comets in 1433, 1449/50, 1P/Halley 1456K1, 1457 I und II und 1472, which didn't reach great public. His opinion was well respected by Cusanus and Alberti.
Regiomontanus, famous (young) astronomer, came to Italy in 1461 on the invitation of Bessarion. He stayed here till ca. 1468. He returned 1475 and died 1476 in Rome. Naturally he also had contact to Toscanelli, how intensive, that is hard to say. Likely they did first met in the period 1461 - 1464 (Regiomontanus lived in Rome, but made journeys). Regiomontanus already had a name then, especially as his teacher, Peurbach, had impressed Italians already between 1448 - 1450.
Toscanelli, born 1497, was then already rather old. He reached a very high age with 85 years and died 1482. Regiomontanus was born 1436, 39 years younger than Toscanelli.
Naturally it should have been a Florentian interest to make Regiomontanus look as a pupil of Toscanelli.

(this source suggests, that Toscanelli had Chinese inspirations)
Quote:
"Toscanelli predicted and made accurate observations on Halley’s comet, which passed by the earth between 8 June and 8 July 1456." ...
“The only piece of his own that we have is his computation of the comet of 1460. It is an excellent computation, as Celoria has shown, and agrees with the figures of Regiomontanus quite perfectly,” says Girogo de Santillan. ...
"Still, he was widely acknowledged as the most distinguished astronomer of the 15th century in Europe. Much of his fame came from a monument to his astronomical skill that still exists at the Cathedral of Santa Maria del Flore in Florence in the well-known gnome, which he constructed about 1468. A marble slab, having a small opening in it was placed at the height of 277 feet in the dome over the middle of the left transept. By the shadow Toscanelli can determine midday to a half-second and could accurately determine when the sun was as its maximum height. (When the sun’s shadow is at it’s shortest)."
"Toscanelli’s friend, Regiomontanus was himself a great admirer of Toscanell. In a correspondence to Toscanelli, Regiomontanus even called him as a “second Archimedes”."
Alexander von Humboldt: "Paolo Toscanelli was so distinguished as an astronomer, that Regiomontanus, the teacher of Martin of Bohemia, in 1463 dedicated his work, de Quadratura Circuit, directed against the Cardinal Nicholas de Cusa, to him."
