Max Multiples: 350 times, be able to see the annular island on the moon clearly!
For the other possible Multiples: (the focal distance is 700mm)

CAUTION: NEVER TRY TO OBSERVE THE SUN DIRECTLY THROUGH THE TELESCOPE, IT WILL HURT YOUR EYE SERIOURLY!!!

How to use the finder scope?
1. When using the telescope for the first time, need to calibrate the finder scope, make finder scope and the main tube in the same direction.
2. First of all, find a more obvious goal in the main tube barrel, it is best to fill the entire eyepiece field of view
3. Then adjust the Finder scope so that the crosshair of the Finder scope is also aligned with the objective of the main tube.
4. Fixed finder scope
5. When you use it later, first find the target with using finder scope, then fine-tuning to locate the target

Multiplying power calculation
magnification times = physical focal distance / Eyepiece focal length
Change the telescope’s physical focal distance to 700mm, take the 20mm eyepiece as an example.
Telescope multiplier = Focal length 700mm/ Eyepiece 20mm = 35X
