Hi.
I am a beginner. I recently got a telescope. Its nothing fancy just something to get started, but I am having trouble focusing it on anything. I tried looking at the moon with it and I couldn't see anything but a white circle. At the rate I am going I'll never get it set up to look at anything else like the sun. Some advise would be great if anyone can help me.
Thanks so much.

A little more detail would help...

@ SwissWalter If I get a chance this weekend. I will take a pic. If you google it. I have it set up just like it looks online.
@marktownley Yes I am using the diagonal. I tried it both ways and with all three eye pieces. I'm still not seeing much.
@Bill Thanks for the advice. I haven't really used it much during the day. (Mostly bc Im not home) But if I have a chance this weekend I will try it again. Just so I am clear I use the 20mm eyepiece not the 4mm starting out?
@everyone Thank you for your help and advice.
