I observed, with my friend Costantino Sigismondi and his students, the occultation of BY Cancri by Saturn and its rings on 2006 January 25. This star is a delta Scuti variable with a very small amplitude, is catalogued as HIP 42705 or SAO 98054 and its brightness is 7.91-7.92 mag. This star belongs to M44, also called Praesepe cluster (Latin for “manger”).
I have shot some picture of Saturn like this:

thanks of Costantino’s reflector telescope and realized with a time exposure of 1/10 seconds at 400 ISO and f/4.9.
Later, with a longer time exposure (1 second at 400 ISO and f/2,8), I’ve captured the image of 3 Saturn’s satellites and of 2 star of the Praesepe cluster, including BY Cancri, labelled with its SAO number, barely visible out of Saturn disk:

Saturn Occultation

Of course the elongated shape of Saturn and the line-like stars are due to the Earth rotation and, consequently, to the rotation of the celestial sphere.
For further infomation on this occultation, I suggest to visite the IOTA page on this event.

My friend Giulia was traveling by train on the seat in front of me when I’ve captured this photo (exactly 8 days ago).
Her thoughts was lost not merely in the reading of a magazine, but they was running through the space while her reflection was merged in the landscape dragged by the train motion.
This picture evokes peace because of the transparency of her ethereal image, but she evokes also worrying because of the message of restlessness provided by the speed of the train.

This picture wasn’t graphically manipulated, and it keeps some blur on the window and some unaesthetic glints come from a carriage’s lamp. I’ve chose to keep this impefections to preserve the orginal atmosphere of the moment.
