Cool!  The OP should keep in mind that the spectral range may be limited by the glass and the IR filter in his camera.

<p>I was wondering if it would be possible to record the emission/absorption spectra of stars without expensive spectroscopy equipment. Would it be possible to somehow utilize diffraction grating? I own a Newtonian with a 130mm aperture if that helps.</p>

Here is a link to a [diffraction grating](https://www.rspec-astro.com/star-analyser/) that can do what you want. It is mounted in a 1.25" filter ring that attaches to an eyepiece, or to most astro cameras. I believe they also sell adapters for other cameras and software to extract spectra from the photos.
