First attempt at a long exposure

I was hoping to get some star trails. But I obviously need more time to really get them to arc. It was a full moon so it was too bright to get it. It is amazing what shows up in this type of shot. There are highlights on the bikes from our campfire that was probably 100ft away. Not what I was really going for but I like it anyway.

What do you think?

    How long an exposure was it? You can always get a longer shutter time if you use a neutral density filter. Or take multiple long exposures one after the other and layer/blend them.

    Not sure on the exposure time. I looked at my watch....then forgot about it. We had a few drinks by that time....... I know I did have the ISO way down and was at something like f20. So I think a ND filter would help a lot. So would a lack of a full moon.

    On a side note. How important is in camera NR for a shot like this? I had the long exposure NR set to normal and it took as long to do that as it did to take the picture. What I found is it KILLS batteries.

    I'm pretty sure an ND would have the opposite affect and diminish the star trails rather than enhance them. I've never tried it, but intuitively it doesn't make sense. The sensor is not going to continually accumulate light from the stars because they are moving, so the ND will dim them. The rest of the scene is a continuous source of light and will continue to gain brightness however.

    I would think the trails would be longer but dimmer. A better solution is to shoot when the moon isn't so bright.
