Goodbye Cassini

Here is an image of the planet Saturn as seen from our back garden in Brisbane, taken through my telescope on the evening that the Cassini spacecraft made its fateful plunge into Saturn's atmosphere, ending this incredible mission just one-month shy of Cassini’s 20th launch anniversary.

The spacecraft and its impact are well beyond the ability of my telescope to resolve, so no live crash-and-burn photos.:-)

It was a poignant evening, gazing at the images on my computer screen as Saturn appeared to dance to the tune of the scintillations caused by the jet stream’s impact on the Earth’s atmosphere.

Cheers

Dennis

Will be interesting to see what they publish tomorrow, if they do. They tend to publish within a day or two of receiving data and releasing to the public.

Will be super interesting to see the atmosphere right before it crushed Cassini.

I don't think any terrestrial telescopes will be able to resolve Cassini's fireball on Saturn when it happened around 8am. It's smaller than some of the ice crystals in the rings, and we can't even begin to resolve those.

Very best,

If it were bright enough, we could see it but larger than "actual size". It would appear at whatever resolution allowed by the sensor and lens system.

Single molecules are mostly much smaller (I'm not including polymers and some large biomolecules in the discussion) than the resolution allowed by light microscopes, yet we detect the light emitted by these routinely. See https://www.microscopy​u.com ...e-fluorescence-microscopy (external link) for a list of references.

I understand that as there is little/insufficient/no oxygen in Saturn’s atmosphere to support combustion, NASA were not expecting a fireball event?

Cheers

It is possible to quote any post, with multiquotes it is easy to pick them around the forums. It is wise to check the preview before posting, though. I'll edit the post for the correct quote now.

Hi Folks

I just added some more IR 642nm data to my Saturn LRGB image and after performing “Digital Development” in Lightroom and “Add Space Object enhancement” in Photoshop CC, noticed a strange, geometric object in the bottom left hand corner – I wonder if this could be a candidate for the Cassini Spacecraft!:-);-)a :p

Cheers

NOPE !! You would never see that Cassini even in the worlds largest telescope . Nice copy/paste edit , nice try tho .

This is absolutely amazing. I never new a home based telescope could get that up and close view of some of the distant planets in our solar system. unfortunately, living in NJ, mid-way between NY and Phily, we have way to much light pollution to get celestial images.


Thanks -
Justin

Hi Justin

If you want to see some awesome amateur Planetary & Lunar images, have a look at the website of Damian Peach (external link), one of the best amateur astro-photographers on the planet.

In terms of the solar system objects, you can take photos from badly light polluted sites as those objects are so bright. Galaxies and Nebulae will suffer as they are dim and extended so are severely affected by light pollution.

Our Moon in particular is quite rewarding as you can capture some lovely detail even with relatively small telescopes.

Cheers

Dennis

Dennis,

Thanks I will definitely check out Damian Peach's pics. Thanks for the link. I am just diving into macro photography so once I need some new subjects, i'd love to look to the skies. I've been out west and also have also been offshore on small yachts and it truly is amazing what you see up in the sky once you are a few hundred miles out and away from the light pollution. 3 years ago I was about 200 miles north of Bermuda at the helm (my other interest, sailing) when the moon broke the horizon. It was almost a full moon but at the horizon, it looked about 10 times the size of a 'normal' moon view. Unfortunately, the seas would never let the boat be stable enough for a good picture!

Justin


Thanks -
Justin
