Been using the three hole mask as per Paul Gittos suggestions on his
website http://cometman.com/Mask.html
This has been a great help for me and think that his site is very good.
The only thing I do in addition is to use a Sharpening routine toward
the end of the process when the exposures are shorter and also enlarge
these sharpened images. Images are focused quickly and quite well for me
at this stage. Perhaps there are more demanding focusing requirements
but this is a good focus.
I use a JMI NGFS focuser and am using a Pictor 416XT. For eyepiece
projection particularly the focuser works very well.
