Hi!
It's cool to see that more and more microscopy people start to use Julia (publicly) :)
Cool package!
There is another package, called PSFs.jl which @RainerHeintzmann also presents on the upcoming JuliaCon.
Further, there exists this organization https://github.com/JuliaMicroscopy/ to which we wanted to move our packages.
Would you be interested in joining that org?
Best,
Felix (from Jena ;))
