The formula: 
- Objective lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification 
- Objective lens focal length / eyepiece focal length = magnification 

Installation sequence: 
1. Put up tripod, then attach the lens tube. 
2. After the tube is fixed, install the finderscope (for preliminary search of the target object), then install the eyepiece (choose one from the two). 
3. After find out the big goal, then debug with different eyepieces. 

Note: 

1. Multiples of course are not the only, and it depends on the combination of factors aperture and focal length. (For example, if the window is big, the natural light is good, and the view is clear.)
