Well now that both Saturn and Jupiter are out of my field of view , I will wait for tomorrow.

@Marc The "Tyranny" of Earth's rotation for astronomers ;-) It takes some patience, I used to practice using a far away light at night, or top leaf on a far-away tree during the day. This is a good answer. Stick to lowest magnification first (don' worry about seeing detail on the planet) where the planet will appear star-like. Only after you get good at finding it, then start working your way up in magnification.

5mm eyepeices on the cheapest celestron hurt my soul... I coughed while aligned and had to switch back to 20mm to find mars again.

# Finding Jupiter, Saturn

(Asked by: username_0 on 2018-10-19)

I have a Dobson Omegon with a 640mm focal length and a 102mm aperture.  
My finderscope is broken but I can do without.  
I have located the planets with the naked eye but I do I do not see them through my eyepiece.

I can focus perfectly on the moon, using a 20mm eyepiece. (I have a 6mm eyepiece as well.)

How should I proceed?
