So, apart from photos of the moon, what else would you use the lens for?

Is there a TC that would work with my 18-200mm VR?

A closeup of a rose

If you're lucky you won't get any doughnuts in the background, but
there can be dougnuts in the foreground too :)

The lens is just about impossible to focus precisely on a Canon 20d if
I don't take my time for each shot and it's too slow without a tripod.
Like I said too inconvenient for me.
I'm right in the process of selecting an affordable equatorial mount
with driving system for astrophotography. And that's pretty much all
I'll be doing with this lens in the future.

To tell you the truth I don't even know how to find saturn yet.
I wasn't going to share this "beauty", but just to show you what I was
able to photograph with minimum knowledge and preparation, here's
Jupiter on may 19th 2005 at 9:30pm ISO1600 1/500s
http://www.ejarm.com/photo/images/jupiter.jpg
If you know how, you can check if Jupiter was near or far from earth,
but my guess is (by the time of the photo) it was pretty far away, so
it should apear larger in perfect conditions.

When I used the lens as a telescope I could make out bands on Jupiter,
that are just barely visible in the photo. I also tryed with 2x TC but
200x magnification was just too much for my tripod. So there I ended
planetary observations.
No matter how useful the viewing attachment for the lens is, I think
it's necessary to invest in a diagonal, it's very difficult to observe
verticaly.

Here's a link on astro usage of the rubinar

Thanks for pointing me to it. I found it with no problem.
Unfortunately the weather here is a bit cloudy and turbulent. I had to
work quickly and this is one of the shots at iso1600 1/50s
http://www.ejarm.com/photo/images/saturn.jpg
I'm sure with more time, better visibility and sturdy tripod I would
get a much better photo.

When observed visualy it was a LOT clearer and much brighter than I
expected, with clearly shaped gaps between the planet and the ring,
but as for cassini division I can't say I saw it. The tripod I'm using
is beyond critique and the image shakes just by observing, so I realy
couldn't concentrate on faint details. It's pretty frustrating. A
sturdy tripod and equatorial mount is a must.

All in all I consider it a success :)
