Philippe do you have some pics with your home made coronagraphs or some constructive detailes? I'm interested in building one. Thanks

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
and my observatory...

That mount is like nothing I've ever seen
Please, you have to post more about your coronagraphs in the ATM section with lots of pics .
So few amateurs build this scopes it would be a fantastic inspiration to us all, especially with such results .
