1. The problem statement, all variables and given/known data A telescope with aperture 10 times the human eye could see stars down to magnitude? 2. Relevant equations I was not given an equation with the question but I have found the following but I do not know if it is correct. M=Log(2.51188)*(A2/A1)^2 3. The attempt at a solution A1= aperture of human eye-7mm A2= 10* 7 (10>human eye) Log(2.51188)*(70/7)= 40 (to 2 s.f.) I am finding the concept of stellar magnitudes difficult to grasp so any help would be appreciated.
