i built a solar spectroscope with variable slit to do same
40mm scope just like PST
how come they did not make something like this then?

Re: A 19th century PST
Browning made many solar spectroscopes which could be mounted on any refractor to allow observation of the proms using Huggin’s method.
More like a Quark than a pst.

Re: A 19th century PST
I have some illustrations back home.....
Basically a multi prism spectroscope with adjustable slit mounted on an excentric rotating adaptor which fitted the telescope.
The adaptor could be rotated to bring the slit onto the edge of the Sun and when proms were found, the slit opened to allow a full view of them.
Some details in “Imaging Sunlight”, p 60.

Re: A 19th century PST
my scope rotates up to about 200 degrees
then it has a variable slit
i use eq mount with goto to position
slit and track
