The Solar EUV Rocket Telescope and Spectrograph (SERTS) obtains imaged spectra of solar features with resolution around 0.04~\AA\ and high sensitivity. Its spectral range of 170 -- 450~\AA\ overlaps large portions of the Medium Wavelength and Long Wavelength Spectrographs on EUVE, and so may provide help in interpreting the lower resolution EUVE spectra of late-type stellar sources. As an example, we compare SERTS observations averaged over a typical solar active region with EUVE calibration spectra of Capella, a G6 + G2 binary. The Capella spectra include prominent spectral features at 256.5, 284.7, 304.2, 335.4, and 360.3~\AA. The SERTS spectrum indicates that, although these features are generally dominated by a single emission line, they may also be contaminated to some degree by blends of other lines at the resolutions of the EUVE spectrographs, which are approximately 1.0 and 2.0~\AA. This high-resolution solar active region spectrum from SERTS is now available electronically by request to thomas@jet.gsfc.nasa.gov, as are emission line catalogs derived from it.
