Prism spectroscope

I am a new student and I was given a Rayner spectroscope and I am trying to learn how to
get a clear image. My question is a Diffraction spectroscope easier to use?



Prism spectroscope only need to adjust to your eye the focusing tube. the diffraction grating spectroscope I do find easier to use as no adjustment needed.
the spectroscope is not an easy instrument to use you need lots of practice to get your eye in. A lot of gemstone does not give you the perfect spectrum and if you did get a perfect spectrum you would be worried that it may be synthetic. Good gemstones to practice on Garnets, sapphire, peridot, chrysoberyl, most these are reasonably easy to observe their spectrum.
good luck
