Wasn`t aware of this subject posting. The most critical thing you should be doing is keeping a logbook so you can learn from your successes and failures. If you are an astrophotographer though, one shouldn`t need to tell you that, nor how to expose the moon and planets. You should keep in mind that as you double the image scale your exposure time will increase by the square unless you also can increase your aperture.

One little trick I have for exposing the moon is to meter the brightest part and then the sky next to the moon but completely off to the side. I average the readings and use the results as a bracket-point. I bracket two stops to increase my range and waste less film.

Have Fun,
-Rick
