This 3 credit course deals with basic topics in the instrumentation of astronomical telescopes and back-end instruments. There are no formal textbooks for this course. Readings will be posted from time to time on this site. Those and your lecture notes should be sufficient. But I urge you to read the relevant portions from the books listed below to gain a wider and deeper perspective on the various topics.

(1) Observational Astronomy, Edmund Sutton

(2) Astronomy Methods, Hale Bradt

(3) An Introduction to Modern Astrophysics, Bradley Carroll & Dale Ostlie

Course Grading Policy

  • Written examinations will follow the usual pattern of two quizzes and a final

  • Occasionally short articles or journal papers relevant to the topic will be posted on this site. A date for class discussion based on these reading will also be posted. 15 minutes of some class hours will be spent on the discussion. 5% of the course grade is allotted for your participation in these discussions.

  • Assignments will carry 5% of the course grade

  • Scribe Notes: You are expected to take turns to act as scribes for each class. The scribe note for each class has to be put together as a formal lecture note with figures and tables included. A LaTeX template for this will be emailed to you. The notes are due on the third day after the lecture. Your notes will be uploaded on this page. The correctness, quality, and promptness of submission of these notes will amount for 10 % of the course grade.
