Narrowband

H-eta: 383.54 nm
Ca II: 393.37 nm
Fe I: 404.58 nm
Ca I: 422.67 nm
Fe I: 438.36 nm
H-beta: 486.13 nm
Mg I: 518.36 nm
Fe I: 558.68 nm
Na I: 589.0 nm
Ca I: 612.22 nm
H-alpha: 656.28 nm

These images are the first to be processed by a mainly automated process which is still a work in progress. The narrow lines of Fe I (558.68 nm) and Ca I (612.22 nm) expose electrical interference that needs to be addressed:

The Ca II & H-beta lines look interesting - would you pls be able to share closeups of those?  Thank you if so!

Try repeatedly clicking on the image.
The first set is tiny but then I get large disks. :thumbsup:

Hi Apollo,

I'm about to construct a camera with smaller pixels and will attempt Ba again after that and solving the interference problem. No Hg lines present in the solar spectrum according to the reference I use.

The UV mercury I-line would be hiding somewhere inbetween 365nm and 366nm, and the green mercury  e-line is exactly 546.073
