I finally got my tripod (not the best) but maybe when I can take pix like 99% of the members I'll be worthy of a good pod... Anyway I'm outside my balcony and trying to get a detailed shot of the half moon, through the view finder I see most of the craters and stuff, but my pix I only get a bright moon. I'm set to 1/5, F5.6 ISO auto and using the 55-250 lens. I've moved the shutter and appeture around but still no go... I am on a bright busy street, cloudy night w a bright moon... Any help would be awesome thanks

yeah, that auto ISO is the problem...mostly because of how much black there is in the frame. If you're using spot metering though, that would help, but I find for astrophotography, manual works best.

If you want a bit more zoom (for relatively cheap), how about Celestron's C90external link? Granted, you're probably only going to use it for moon shots, and maybe other planetary stuff like jupiter...but at least it isn't that expensive.

My friend went and got one of those and when he gets his adapter, he'll put his 5DmkII on it to take some moon shots. Interested to see the difference in detail compared to my 400mm. Since the design is basically the same as a mirror lens (has that weird donut bokeh) and that rather slow aperture (f/14) I don't really expect him to use it like a normal lens though...

Did you want details like this where the moon doesnt just look like a white dot?

I suggest you use either Av or Manual. In Av, use spot metering with the focus point on the moon.

For this shot. I used 1/400 sec, f8, iso200, -2ev. Evaluative metering will not work on the moon as the camera will think the scene is dark. The moon is basically reflecting bright light off the sun. To counter that, you need to run a fast shutter speed to underexpose the moon to see the details. I didnt use any fancy lens, just the a kit lens. I've also done this with a point and shoot with similar results. try it out.

hmm....I guess I should've said "metering" instead of "auto iso", but oh well. I think you got the idea.

your camera has live view, feel free to use it to get the exposure right as well as for manual focusing.

Looking for a manual zoom on the cheap end? Then check out the 500-600mm mirror lenses on ebay. Find a Sigma if possible. They produce a reasonably good image, and can be had for under $200. You can always add a teleconverter if you need to.

If you find a mirror lens that you like, don't forget to pickup a EOS adapter so you can mount it to your camera.

on my 55-250mm i used f/8 and 1/250s at ISO100 to get a good exposure. It moves pretty fast when zoomed in 10x for manual focusing.
