Hi


Attached are some images of the Sun taken this morning through an ED 100mm f/9 telescope + spectroheliograph + ASI 183MM Pro Camera at Ha, Hb and CaH wavelengths.


Frames reconstructed using Doug Smith's SHG Main software.
Best frames selected and stacked with AutoStakkert 3! then deconvolved using AstroSurface. Frames reduced in size and heavily compressed to fit here..



Wavelength plots compared to reference standards for dispersion evaluation.


cheers
