Enter the telescope aperture (mm) into the Calculator. The calculator will evaluate the Max Resolution From Dawes Limit. 

Max Resolution From Dawes Limit Formula

MR = 116 / TA

Variables:

  • MR is the Max Resolution From Dawes Limit (arc seconds)
  • TA is the telescope aperture (mm)

To calculate Max Resolution From Dawes Limit, simply divide 116 by the telescope aperture in millimeters.

How to Calculate Max Resolution From Dawes Limit?

The following steps outline how to calculate the Max Resolution From Dawes Limit.


  1. First, determine the telescope aperture (mm). 
  2. Next, gather the formula from above = MR = 116 / TA.
  3. Finally, calculate the Max Resolution From Dawes Limit.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
