Research-grade Saturn image March 18, 2007

Marco Vedovato, a (not-just-) amateur astronomer with an interest in planet imaging, distributed yesterday a great image of Saturn in a mailing list I subscribe to.

Marco, who is a regular contributor to ALPO , usually works with lesser instruments than the one he used for the picture shown below, a 80 cm (31.5″) Cassegrain telescope from the Max Valier Observatory. Even given the large diameter, the quality of the image is really good:

Please note – among several other interesting tiny details – the Encke division, a feature I recently claimed to have glimpsed with my scope, which has a diameter half the one used for the image above. The Encke division is the first dark band one finds from the edge of the rings, a fifth of the way to the much wider Cassini division. Encke has a width of only a few tenths of an arcsecond, so it is really, really at the limit of the power of a 16″ scope, despite being much longer and a feature of quite high contrast.

T!!!! I have finally found access to you. I think that i have your email wrong. Email me at intlwmnofmysteryxxx@yahoo.com so we can reconnect and so i can give you my new phone numbers. When you called me last I was sitting in an empty house, with my family, a big truck outside with my things and there was no way for me to naperville. and i understood you couldnt come to morris😦 so alas, another missed opportunity. I am SO glad that i found a way to contact you. Everything is actually going well. I am finally doin more than surviving, we are actually thriving and little by little things are good. I actually can afford a trip there, perhaps at the holidays? .(without the kids, im not doing so well that i can afford all that but i could for myself). PLEASE get in touch. I miss you so much. I need new pictures of the children for my refrigerator and would love to talk to you. Now that i have this website i can read all that is going on with your work. By the way, Nicholas was just speaking of you a couple weeks ago because he was in a chess tournament and WON and he was so excited. We love you and miss you guys so much.

Hi Alex,

you can ask for the original to Marco Vedovato. Send me your mail address or leave it here (I will then erase it) and I will forward you the address of Marco.

Cheers,
T.
