Orion Jewel
NGC 2022 is a gem of a planetary nebula in Orion. It glows with a nearly spherical shell and inner structure.
It also features an very faint outer shell- but this data isn't deep enough and it is too noisy to show. At this resampled image scale of 0.15 arcseconds per pixel careful deconvolution allowed some of these delicate details to be enhanced. Compare with the HST image of the same to see these structures even more clearly. (

One important technique I employed here was to upsample (x2) the data before deconvolution. The result is good enough I left it at this image scale of 0.15" per pixel. The original data had stars with a roughly 1" FWHM. The data was not appropriate for drizzling- but the deconvolution proceeds with much more control with the upsampled image.
