Shadow transit of Titan 13/04/2009

[Quark]

Hi All,

Imaged the shadow transit of Titan every ten minutes from 10:00 UTC until 11:40 UTC. Captured 22 avi files in all including 5 RGB's.

This is one of the RGB's. I will post an animation of the R channel images covering the last 100 minutes of the event. This will take some time, I hope to post it this evening.

This was a difficult event to capture as it commenced very early in the evening. My captures started at about mid transit but even then the Sun was not far below the horizon and the seeing was poor, about 5/10, as it got later the seeing improved to about 6/10. There was an abnormal amount of humidity in the air for my remote outback location. I could smell the moisture in the air, there must have been rain somewhere in the region.

That said I have some nice data and the animation should look good.

This RGB was the final one I took for the evening. I will post the other RGB's later when I finish processing.

Thanks for looking
Regards
Trevor

That's really nice, Trevor. The shadow is nice and round, as is Titan.

We were clouded out yet again so I missed this transit. It's been a pretty shocking transit series for me. There's only been one (the first one of Titan) that I haven't been clouded out for.

Thanks for sharing! I look forward to the animation.

Well done again Trevor, was raining here last night so I missed this event. Good to see you had clear skies for it!

cheers, Bird

A lovely image Trevor; talk about casting a giant shadow! The scale of these events is quite mind boggling, given the size of Saturn, its ring system and the orbits of its moons.

Cheers

Another great capture Trevor! Well done.

Very nice detailed capture Trevor.

[Quark]

Thanks Lester, I was quite pleased with this result.



Thanks Stephen, always trying to improve what I do.



Thanks Bird, mostly we have clear sky's and good seeing out here. That has been most advantageous in supplying Georg with storm data.



Thanks Mike, I am pretty pleased with how Titan came out with the RGB avi's being short enough for each channel to line up for Titan. I think the first transit is the only one that I missed.

Thanks Dennis, yes it all is pretty amazing, Saturn 120,000 km diameter and at a distance of about 1.4 billion km and to see the relative size of Titan compared to the diameter of the shadow that it throws on Saturn. To be able to see much detail of this from Earth with amateur equipment is amazing, what would Galileo have made of it, I wonder.

Cheers

Nice image Trevor,

Not clouded out here for me, I was just too soft after being ill all weekend to go out and image. I am so glad someone got an image of this event. Many events this year have been missed. Well done with a lovely image.

[Quark]

Thanks Paul,

Sorry you missed out, it is no fun being out imaging when you feel crook.
However I do look forward to seeing what you can produce from your new observatory, Clayton is a top spot and the no street lights policy must be great for astronomy.

WOW Trev!

Nice work.

Is the South at top correct though?
Shouldn't it be North at top?

Apologies if I'm wrong.

South up is the technically correct presentation method. However, sometimes a planet looks better the other way.

[kinetic]

Yes sorry Paul, I meant the orientation Trev has shown just conflicts with
his animation.

BTW Trevor, I think the animation is brilliant.
That moment of clear seeing in the middle is like a cricket bat
to the face! You are a master of your craft, well done!

Hi Steve,

The orientation of the stills and animation is the same, South up and West to the right, I have just stuffed up with the text for the animation, Ill blame lack of sleep for that.

Cheers
Trevor

WOW!!

thats fanastic! what an amazing pic

extremly well done,its always amazing to see moon shadows on a planet

to see these events in real time,or take pics and vids like these,is a nice

experience,seeing the cosmos in action,


i hope the animation comes together

cheers Chris:thumbsup:
