the June 6 New Moon festivities at my place near Frazier Mtn

Dark Frame = Average of 3 images
Flat Field = Average of 9 images
Unsharp Masked and Stretched
False color rendition
The distorted star images are thought to be
caused by a very bad Al coating. This defect
was not noticed until the AO system was used.
The mirrors are now being recoated
FWHM on the star images is 2.0 arc-seconds
The image below has been run through a modified
Lucy-Richardson Deconvolution Algorithm
It has also been unsharp masked and stretched
after the L-R processing
