Greg.
Indeed...I mentioned the RAW data was not perfect in an earlier post. The de-con routine definitely causes the stars develop processing artifacts. I'm hoping oversampling will mitigate this. All I can say is: watch this space.

The best I get here is about 1.8 arc sec seeing. In general terms, deconvolution works best with oversampled data, which hopefully will avoid the artifacts mentioned above.
