Cloning?

I would like to get rid of the lights that are poking out of the dome on the left side of this photo but have minimal PP experience. I have access to Adobe Elements, Gimp and PhotoPlus.
Anytime I have attempted cloning it sucks royally!

Any suggestions as to best fix this?

Thanks!

 

You can fix that in photo elephants lickity split.

Thanks--here's my attempt.

 

Not a bad attempt!
You can still see a few bits on the edge of the dome

 

Nice work... Pretty good for not being used to cloning. Skies like that make it much easier to work in as well - the cloud as so much detail, you can easily hide a little sloppiness in cloning the cloud just using a soft edged brush...

 

Thanks, I have tried it before with little success, but this was the first time using Elementals and I found it much easier for some reason. Now to work on all the other things in PP
