Hi Troy!
sorry I'm not using either for deconvolution. To be honest, I only know iris. Will give imagej a try soon.
I'm regularly (quite always) using Fitsworks deconvolution on my H-Alpha images of the suns surface. Fiteswork is free software and does have some really nice functions. I especially like the iterative gauss sharpening

Maybe this helps
