====== Low‑Cost Telescope (LCT): Active Learning Astronomy ======
<label type="default">Project Lead: Inseok Song</label>

<WRAP group>
<WRAP left round info 90%>
The Low-Cost Telescope (LCT) Project addresses a critical gap in astronomy education: the lack of scalable, hands-on observational experiences. Traditional astronomy labs heavily rely on expensive, department-owned telescopes, severely limiting individual student access and reducing opportunities for student-driven learning.

Our solution provides a model where each student has access to an individually operable, low-cost telescope setup paired with accessible digital imaging detectors (like smartphones or low-cost CMOS modules). This methodology shifts the paradigm from remote data consumption to authentic, end-to-end scientific processes—including instrument physical setup, target alignment, calibration, and data reduction.

The LCT project democratizes observational astronomy by pairing affordable telescopes with student-owned cameras. Learners plan and execute real observations—operating instruments, acquiring data, and analyzing results—to build genuine scientific proficiency.


===== Why LCT? =====
  * **Hands-on instrumentation:** Students learn telescope setup, alignment, camera operation, and calibration.
  * **Authentic data pipeline:** End-to-end workflow—from observing to preprocessing, stacking, analysis, and reporting.
  * **High access, high skills:** 1:1 student-to-telescope model supports repeated practice and deeper learning.
  * **Scalable & affordable:** Four budget tiers (B1–B4) adapt to K–12, undergraduate, and outreach contexts.

===== How LCT Compares =====
Traditional campus observatories offer strong hands-on skills but limited access; robotic telescopes provide access but little instrument proficiency. LCT uniquely delivers //both// access and skills.
