[jordan20]

what one is better for astrophotography i know the D3000 has a 10.2 mp CCD but the D3100 has a newer 14.2 mp CMOS. So what do you think

My D3100 works fine in astroimaging. There is a bit of noise at the higher ISOs, but that is expected for a entry level camera. Megapixels are a little overrated in this field, most people use modded Canons with low megapixel counts but get great images. I think it comes down to whether u want the extra resolution? If you are going to use this as an all purpose take every type of image camera, than it might be better to get the D3100, otherwise the other should be fine.
