Spectroscopic capture of Vega

[+Graham]

Not quite sure where to put this.

First Spectroscopic image I have taken.

 

The box on the left is the captured image of Vega and the spectrum it produces.

The large box on the right is the calibrated result.

The spike on the left is Vega the rest is the calibrated spectrum.

 

This shows the Hydrogen absorption lines in Vega.

Processed from a 30 second AVI file.

 

 

This is the full range including the background noise from space.

Processed from a single Jpeg image.

Well done on getting a good result straight off from the start, Astro stuff usually has a big fight before it gives in and works.

 Interesting stuff ,so what else does this tell us Graham I’m assuming the other colours relate to other chemical compositions is that correct

[+Graham]

The colours are the wavelength of the light. From the blue end on the left to the red end on the right. 

The chemical elements are found in the base of the troughs. 

If you measure the reading of this trough it will relate to the chemical element 

You can also work out the temperature of the target and by comparing two images taken a known time apart you can measure whether the target is moving towards or away from you and at what speed.

Fasconating stuff Graham

[+Derbyshire Dave]

Amazing and fascinating. Never seen anything like this before Graham.

[+RonC]

Could you discern the correct filter for a target using these results Graham?

[+Graham]

I cannot see why not Ron.

[+Glafnazur]

This is really interesting stuff Graham. I am looking forward to seeing more results.

What I especially like about this is that it is a departure from the usual shots that most of us post and is very original and brilliantly thought out.

Excellent stuff Graham.

Vega is a multiple star system, (not often listed as such) so this is the right section to post this on
