I don't know if two minutes is too long for this object but even after applying lights and darks I can't get a good image with about 1 hrs worth of exposure.

(the first image was compressed to 8 in PS7 whereas the second I had to set as 4 to get under the size for posting both where saved at 800 x 532)
