Interested in Introductory Non-Standard Analysis Books?

[Q-1]

Hello,

I am interested in any introductory books to non-standard analysis. My highest level of mathematical education is Calculus II via community college. Any help appreciated.

Start with Jerome Keisler’s book. It’s free on his website, also available in a Dover paperback. https://www.math.wisc.edu/~keisler/calc.html

Are you interested in the more theoretical or more practical side, i.e., how to use non-standard analysis or the theory part? Or both?
