Transit of Venus. June 8, 2004

Transit of Venus
8 june 2004, 9h44 UT
25cm Newton, f/D=5.7 with Mylar sheet
FTT1010-M in prime focus
Additional ND3, RG630 and IR filter
Exposure: 0.1 seconds
(Eclips sequence here)

Second (inside) contact of Venus
8 june 2004, 5h39 UT
Images separated by 15 seconds
25cm Newton, f/D=5.7 with Mylar sheet
FTT1010-M in prime focus
Additional ND3, RG630 and IR filter
Exposure: 0.1 seconds

The black-drop effect is mainly caused by the (limited) resolution of the optical system and the image contrast (or contrast perception of the observer). More regarding this effect can be found here.
