As most of you already know or have noticed, I'm a big fan of photography and I practise it myself aswell. Over the years I've gotten myself some nice equipment and photography has become a big hobby of mine. I make photos at work, at home, during my holidays, weekend trips, etc. Pretty much everywhere I go, my camera bag is there with me. My equipment consists of a wide variety of lenses (ranging from 100mm up to 400mm, with a possibility of getting up to 560mm), 2 bodies and a fair amount of batteries, memory-cards and a few other accessories.
I created this topic because, like the vast majority of the photographers out there, I like to share my work with other people. I'd like to share some of my material with you guys, so when I make a photo I really like and want to share, I will post it here. Comments/tips/hints/positive criticism are all much appreciated.
If you have any questions, if you don't understand something, if you want me to explain a certain technique, etc., please don't hesitate to ask. So if you see a photo somewhere and wonder how it's done, just post it here and I will try to explain. I can't promise that I can have a definite answer (I don't know everything), but I'll do my best.
And last but not least, if you have some nice images yourself, feel free to post it here! Just don't spam/post many photos at once. If you made a series of nice photos, pick the best 1 or 2.

So I'll start off. I took the photos below at work this morning, the sky was kinda clear and so I decided to try and go for a moon shot. The set-up looked like this:

My 40D (w/ battergrip), mounted onto a sturdy Manfrotto tripod and a 1.4x Extender between the body and the 100-400 lens, giving me a total of 560mm zoom. The downside to using the Extender with that lens is that I have to manual focus. But since the moon doesn't move THAT fast, it was quite alright. The chord you see dangling from the camera is a sort of remote, so I wont have to touch the camera when pressing the shutter button, thus eliminating any vibrations I might cause.
The result:

I'm happy with it, but there is room for improvements. Next time I try this, the moon needs to be closer (so it's bigger), in which case I won't need this much zoom, which in turn will enable me to use the auto focus again
