You really need to look at the whole Z stack to determine the problem. Would you put the TIF stack on Dropbox along with the capture metadata?

Hello,
I am observing some sort of an aberration (looks like coma) when imaging
sub-resolution sized fluorescent beads under epifluorescence. I am using a
Zeiss Axio Observer Z1 microscope with a Zeiss C-Apochromat 63x Water Obj.
NA=1.2.
I match the collar correction to the coverslip thickness but the airy disks
are not complete. I uploaded one of the images here
(https://www.dropbox.com/s/kst4plbrqmv29hn/100nm%20100x%201.0s.tif).
Image was taken with a sCMOS Camera (Hamamatsu Orca Flash v4.0) attached to
the side-port of the microscope. Particles are excited with SpectraX light
engine from Lumencor through a GFP filter set from Semrock.
Has anyone come across such problem? Let me know if you have any ideas about
what might be the possible causes?
Thanks
