More Spectrums

[johnb]

So here are some more captured recently, all caught with a QHY5 and Skywatcher videos processed in Registax and processed in RSpec.

I'm getting better but still need to capture better spectrum's, mine tend to be under exposed, also now I have caught a few I will need to create a new instrument response as I removed to much. Anyway thanks for looking and feedback always appreciated.

Two images per star, the instrument corrected and then normalised.

Vega - A0v 

Algol - B8v

Capella - G8iii

John,

Looking very promising...

I think there's still some work to be done on the instrument response. There's still a "beat/wave" showing in the Vega spectrum which should not be there.

You may have over smoothed the correction curve.

Onwards and Upwards.

You may have over smoothed the correction curve. - Which will of course impact all other spectrum's

beat/wave in Vega - err where ?

John,

In the vega spectrum you seem to have four waves/ dips between Hb and Ha which I believe are artifacts.......

(We have seen similar issues/ problems with other cameras.....)

Hope this helps
