Michael,
They are not impossible. They just take some patience, mostly in polar aligning the telescope with an equatorial wedge on the tripod. Good planetary images can be taken with a webcam and some stacking software. Check out my profile or web page for some examples.
I don't believe that the exposure was as long as 4 seconds. It was probably close to 1/125-1/250 sec., as the moon is a sun lit object. Since it is made of dark stuff, the sunny-11 rule is used: 1/ISO for f/11 as the starting point. You may need to go up or down a stop depending on phase.

I have a celestron nexstar 12". I got it a week before the gps system came with it. I would recomend the gps system. It is great for photos of the moon, and sky watching. But those deep space photos that you see on magazines and websites. those are near impossible to do, and you either have to take multiple exposers or have great computer equipment to develope the colors and detail of planets or nebulas. Over all though I love to use telescopes to just look at the sky, and with a better eyepice, I can look at a larger crater that would take up the entire field of sight. :)

Great work Michael, very sharp and detailed. Good exposure too. What kind of scope do you have?

I used my small digital camera it doesn't tell me what I used once I have taken it off the card. I useually set it for 4 or 5 seconds though. I took that shoot through My telescope with a 40MM lense on it. I took the moon filter off to take or or it adds a yellow tint to the photo.
