Sun from Melbourne 18th May LT

[Maurice]

Hi

Attached are some solar images taken on the 18th May LT from Melbourne.

102mm f/9 refractor + home built spectroheliograph.

Data selected & stacked with AutoStakkert3!
Deconvolution with AstroSurface.

I have included images in Ha, CaK, Na (D1 & D2) and Mg (b1)

Seeing varied between 2.4" to 3.3".

Better Ha image here: https://flic.kr/p/2pRLrRB that can be downloaded.

All images reduced & compressed to fit here.

For interest I have also added spectral fit lines against a reference standard also showing the dispersion.

Cheers
Maurice
