Re: Fun with the AstrHori 25mm

Hello Doug,
First of all, congratulations on buying a new lens.
I can well imagine that it's fun to work with.
I don't have this lens and would like to see what photos can be taken with it.
Best, ADi

Re: No sharpness when using mitutoyo 10x (also halo, low contrast)

Hi,
OK, if everything is OK with the lighting, then I would check the rail.

2) Is the rail sufficiently well centred?
There is a long red artefact worm in the top right of photo 5x.
