Occultation of Jupiter - 2012/11/28

[jsmoraes (Jorge)]

I went late to imaging and I captured the first image.

But I would like it had been the second image.

Nice work, Jorge! Still a great sight to be captured in one frame.

Based on your simulation, I started playing around in Stellarium to find out where the best vantage point might have been to view/image the occultation.

If we had been in the middle of the South Atlantic Ocean, near the Rio Grande Rise, then we would have seen a partial occultation of Jupiter by both our moon and Ganymede at the same time!

WOW!! Great captures Jorge I love them both!

Is this imaging done by way of composing 2 or more images or is it one capture? I wonder if you could point my in the right direction so I may attempt one at next occultation

Carlos, it was 3 photos, iso 100, direct focus:

1) one with 1/25 second to Jupiter's moons and they were enhanced with distort-shear and distor-spherize from Photoshop

2) one with 1/200 second to Jupiter and it was enhanced with unsharp mask from Photoshop

3) one with 1/500 second to Moon and it was enhanced in Registax

I loaded all photos on Photoshop and aligned them. With ressource of select, copy, paste and layer mask I hide or reveal to get Jupiter from one, Jupiter's moon from other and Moon from another. Flatenned image... and ... that is it !

Jorge, is there another occultation of Jupiter by the Moon on Dec 25, 2012? In CdC it looks like one happens around 20:49-22:04 (local time) for the area around Rio de Janeiro.

[jsmoraes (Jorge)]

Yes, Andrew. And I live near Rio de Janeiro, 100 km. I hope I will be ready on time.

But if a I see something like Santa Claus and his sled I will consider it will be an UFO with an ET

Muito obrigado Jorge

They are very nice compositions! I hope to try something similar soon. An occultation with Saturn would look beautiful too

Fantastic images Jorge, the second has superb detail!
