Solar spectrum

Post by Montana »

As it was wet and cloudy at the weekend I managed to put together the spectroscope that Mark T gave me at the International astronomy show. I was blown away at how good it is, I threw away my champagne box one as this one you can clearly see the lines (rather than guessing) and you can see them cyrstal clear in cloud too. I look forward now to taking this on outreach events as it is compact and obvious, I didn't like to use the other as it was not at all obvious. I managed a photo although the yellow seems absent. Any help identifying which line is which would be a blessing.





Such a lovely little instrument, thank you Mark :)

Woohoo! Glad it's working for you, they work ok :)

You can easily see the dark line of Ha in that spectrum. Great picky too!

Glad was of use to you :)

Alexandra,
Well done!
I think you're picking up the basic Fraunhofer lines (just google for details)
What does the slit at the front look like - if the focus is OK then may be a narrower slit will make the lines a little "crisper"

Thanks guys :)

My slit was a little large and bent, so I used my two razor blades from my champagne box one and this made the lines much more distinct :)

Hi Alexandra,

I believe you have identified the major ones, although the bottom two look like they might be oxygen and then H-alpha, but Ken and Mark are the experts.




You might also be interested in seeing the full spectrum!

Please tell us more about the spectroscope you are using.

Thanks

Regards

Alexandra,
Looking better...
With such a low resolution some of the lines are blending...
I think you've identified the main ones.
The dark "dip" you show, just above the Sodium, is an artifact of the DSLR. This is caused by the overlapping of the Bayer filters - reduces the camera response in this area. It can be processed out using an instrument response curve.
(Looking again...your focus may be a smidggin out - the vertical edges should be a bit sharper....)
