Crater Ptolemaeus - Stacking versus selecting the best frame

The technology of processing AVI sequence was enhanced during last years. Before Registax release it was considered, that the best method for Moon photos was to select the best frame from AVI sequence. The result produced by Registax shows very clearly, that now we have even better method - stacking several best frames and wavelet processing.


The single best raw frame selected from AVI sequence.
 
37 frames best frames stacked and wavelet processed in Registax

Conclusion

The stack result produced by Registax is much sharper and less noisy than the best single frame.
