Hi all.
Paul R (1ponders) has written a
fantastic article about the hartmann mask for the
IceInSpace How-To's page.
He goes into great depth covering topics such as how the holes in the mask affect the diffraction spike patterns, the best configuration of holes to get the sharpest spikes and therefore sharpest focus, how to actually use a hartmann mask to get crisp focus, and of course how to construct one.
It's a really nicely written article, thanks heaps for taking the time to do it Paul. Read the article here:
Secret of the Hartmann Mask... Revealed!!
If anyone else is keen to write a how-to guide for the IceInSpace site, please contact me. I'd appreciate your time and effort.
