The transit of Mercury – May 9, 2016

Sometimes objects fly in front of the Sun: bees, birds, planes, the International Space Station…and sometimes planets also.

Today it was Mercury that transited the Sun.

Not the best conditions for this imaging session, but I did manage to observe the event with my wife, Eli, from the Comana Woods, south of Bucharest.

For now, only a few shots are posted, since the 200Gb of data will take some time to analyze.

The image below, was acquired using the 115mm F/7 APO Refractor and 3x Barlow lens, full aperture Baader solar filter, ASI 174MM camera and a Baader Red filter. Seeing was 4/10, with a lot of clouds passing rapidly.

Eli did a time-lapse transit evolution with Mercury in different positions. Note the unequal distances between the positions since she captured the shots between the clouds:

And a short animation showing the great differences between white-light and H-alpha  in solar imaging:

Thanks to Adrian Sonka, I could use a Coronado PST (40mm) which “sees” only the light emitted by the Hydrogen atoms. It offered the best views while observing the event at the eyepiece.

A wide view with moderate resolution (for 13:42 U.T.):
