Excellent professor ,made a dummy like me understand...Also I had no problem understanding him, even though English is not my native language... Very interesting subject, well explained. Recommended

We learned this fantastic method for analyzing astronomical images using ds9. Dr. Matilsky is a great teacher, he made the difficult topics fun and correctly showed how to solve the problems.

Amazing detail, amazing insight. Take your time with this course, and dig in. I may have to take if a few times if I have time.

I love the way the professor explains things, and the fact that this course is evidently tailored to the Coursera audience. Strongly recommended!

Thank You! Very good course, different with actual data to handle. Thank You Terry Matilsky for your lessons. They were excellent.

While the subject matter is great, the prof does not go over the maths you will need. He presents a formula, works it out without much explanation, then it's up to you to pull algebra manipulations on a "practicequiz". You don't get to practice before the quiz! You don't get a final exam! You don't get a good explanation until the last week of something you needed a month ago! I found myself reviewing videos and reading material, confirming the answer was NOT to be found there, and then researching online over and over and over again. I passed the course yet I STILL don't understand the quick energy analysis peaks, etc. The DS9 suite is outdated and very Win 3.x style of clunky. There is no "undo" button, and so you can find yourself restarting everything several times. It also doesn't magnify the font; available only in eyestrain-o-vision. While this has nothing to do with the course execution, it's an additional annoyance not to have a current tech program. I was resolved to understand Xray analysis, otherwise I would have dropped such a poorly taught course in the third week entirely due to poor "teaching".

Use of DS9 tool to explain the science is spot on !

An amazing course. I learned a lot of tools for an astronomical analysis. The topics was very well explicated and the lectures was very helpful.
Will be awesome if there were a week/topic where explain all the ds9's tools and options, or at least a tutorial on a web page.
