Here we go!
I got the opportunity to get back to sorting the L200 and ST8 today. Here's the first spectrum off the rank - Fraunhofer F. I've got C, D, E and G to process yet.
These were first light after focussing the ST8 on the slit. It was a cloudy day so the L200 was just pointing through the window - no scope. 3 x 30s images were stacked after dark subtraction only, preprocessed in IRIS (another learning curve
). Slit was roughly 20 um (I need to check it after having the pull the L200 apart to refit the shutter after I broke it fitting the neon reference lamp
). Dispersion is about 0.92A/pixel. No flats or bias, no instrument response correction.
