VENUS TRANSIT 2012 (June 5-6)

Venus transit images taken by my son David in KK, Malaysia

Probably the best maximum image (processed from .NEF) ...click on it for a larger one...

Best 3D transit reconstruction from time interval images at maximum transit :

Click on image for full size anaglyph or here for full size // vision, here for interlaced and here for cross-eyed

New ! Color versions from original RAW (Nikon NEF) pictures !

Click on image for full screen anaglyph or here for full size // vision, here for interlaced and here for cross-eyed

Click here for a short egress avi (animation in divx).

Now images of the third and nearly fourth contact ...

All pictures taken with a Nikon DSLR camera and very old white Meade 100/1000 mm mak on a tripod

3D transit reconstruction from time interval images :

above cross-eyed view ... click here for // and here for anaglyph views.

A little experiment with live streams !

Both live streams present on same PC with 2 monitors captured at the same time (PrintScreen, many screen captures done).
Distance of observatories broadcasting live on Internet (Exploratorium, San Francisco, California, USA and Weizmann, Rehovot, Israël) ~ 11940 Km (from Google Earth mesurement). Yellow image from Exploratorium, grey image from Weizmann, two versions after approximate rescaling, orientation and superposition.

Hint : if you want to see the best pictures available of the Venus transit see this great site : http://legault.perso.sfr.fr/

Previous VENUS TRANSIT in 2004, June 8 (IDF France) in H-alpha and 3D

Click on above picture for a large size in anaglyph 3D mode

Using the links provided below you will be able to see in full screen other commun 3D formats suitable for your monitors or 3D TV (via HDMI) :

Parallel

Crossed

Interlaced

You will have the impression of seeing the black disk of Venus somewhere between you and the Sun !

Some explanations :

Telescope : Perl-Vixen 4", F=900mm, H-Alpha 90mm Coronado filter, Canon EOS 10 D and Philips webcam (moded with BW CCD)

This is not a real picture ! It is a photo montage realised from two shots separated by 20 min.

Intensive post-processing with RegiStax, Corono and especially SPM (Stereo Photo Maker).

It nevertheless gives an idea of what we could see if our eyes were separated by about 40 000 km !

Please have a look at my astromovie of the full transit here.

H-ALPHA INGRESS

State of this latitude of the Sun ...

Click on one of those pictures to see (or save as with right click) a high resolution H-Alpha astromovie

of the ingress (6 x accelerated, DVS stabilized)

In the sequence just below (40 registered frames then an interval of 8s in between pictures),
I did not see the so called "black drop" effect (click on image for full size) ...

Below a cross-eyes 3D vision showing Venus shadow floating in space (time interval used 40s):

H-ALPHA EGRESS

H-alpha environment at egress time :

Jet prominence :)

Click on one of those pictures below to see (or save as with right click) a high resolution H-Alpha astromovie

of the egress (6 x accelerated, Registax6 + Registax5 + DVS stabilized ... due to very windy conditions !)

Caution : due to the high quality, length and framerate of those astromovies, their size is just below 50Mb !

Just after egress from the chromosphere, Venus was not seen (should be center of red square)
even when greatly increasing the webcam gain
