Instrument Selection25 ptsThe two chosen instruments are a defensible best fit for the three requests, given what's actually on the shelf.A reasonable choice with one questionable call.Selection ignores an instrument's clear strength or weakness.No clear selection made, or selection is arbitrary.
Technical Justification35 ptsCorrectly applies light-gathering power, resolving power, and (where relevant) what a spectroscope needs to function, to explain each choice.Mostly correct application; one concept is thin or slightly off.Contains a real misconception (e.g., treating the spectroscope as useful without a telescope).No real technical reasoning given.
Defending the Trade-off25 ptsClearly explains what's lost by leaving the third instrument behind, and why that's an acceptable trade for tonight.Trade-off is named but the reasoning is thin.No real acknowledgment of what's being given up.No trade-off discussed at all.
Clarity & Process15 ptsMemo is well-organized, professional in tone, submitted on time.Mostly organized and on time; small issues.Disorganized or late.Not submitted.
