My relatively ancient Sony makes the Sun pink. In both cases I used
the same old, Baader foil, full aperture filter.

Even further off topic, is it true that you can get a colored glass
"hydrogen alpha" filter that does not cost thousands of dollars, but
has a wider FWHM that the serious ones?

You can get something like

which costs a few hundred dollars and has a 12nm bandpass; or 50% more
for a 6nm bandpass; they'll get you lovely pictures of hydrogen
emission in the Milky Way and the Local Group but are no use for solar
work. The cloudnights forum suggests that 1nm bandpass is absolutely
the bare minimum for visual solar work.

http://www.daystarfilters.com/Quantum.shtml are tunable etalon filters
with down to 0.03nm bandpass, but price is roughly inversely
proportional to bandpass.
