Phil, absolutely stunning images! For self-made filters obtaining this level of high resolution, you should really consider custom making and selling them to people. Can't wait to see part2. Thanks for posting them

Regards,
Steve

Alex, here an image of the 150 mm self made coronograph on a big secia mount (very good precision)
lenses made in BK7, first one 150 mm F/15 lightly aspherical and the second one 64 mm F/2 hardly aspherical also.
then a 100 mm doublet (25mm diameter) and h-alpha filter 5 A bandpass.
for a normal coronograph, you have to use mine lens as possible (ideal 3 or 4 lenses)
first lens can be realised with schott red filter (610 or 630 nm) max
