A very cost effective alternative is one of the 3D printed "Sol'Ex" mini spectroheliographs.
This allows you to image in any visible wavelength - Calcium, Magnesium, Sodium, Hydrogen etc etc.

Hi Ken,
The Sol'Ex looks interesting. Way cheaper than a dedicated solar scope but I don't think I'm that good at the DIY type thing at that level. So I'll have to save for some time for anything more than white light.
Cheers,
