Thank you
Update: Just using my 4mm eyepiece, I was finally able to spot Moon in its full glory! it was so majestic!
But the only problem now is the telescope assembly isn't too sturdy. I still need to figure out how to keep it steady.
Should figure that soon!
I've contacted the seller for replacing the barlow, he too suspects its faulty.
Let's see how that goes.
Congratulations with the 4mm.
This is the 3x-barlow that comes with our "PowerSeeker" kits, and with
all "PowerSeeker" kits...
This is the bottom of the barlow, the end that's inserted into the focusser; you can see the lens there...

Let's have a closer look at it. Here, the camera and a pen-light approaches the top of the barlow, and where an eyepiece is inserted...

Down we go into the barlow...
I see a black-plastic retaining-ring with notches. Let's unscrew that and take the lens out...
It's only one lens, and of plastic. It is flat on one side, which points down into the focusser; and bowl-shaped on the other side, where it points towards the eyepiece and the eye. It is a plano-concave lens. It's rather thin, therefore I assume it's a singlet. It could be a cemented doublet, but being of plastic it's difficult to tell. But for all practical purposes, it's a single lens.
I had to use a tool to remove that single lens from the bottom of the barlow. Are you certain that you're having trouble with the barlow?
This is the 20mm erecting-eyepiece, which comes with our "PowerSeeker" kits...
Many who purchase these "PowerSeeker" kits have problems with that eyepiece, as it contains two lenses and two black-plastic spacers. Quite a few accidentally, or intentionally, unscrew it from the top, then the lenses and spacers fall out onto the floor. Is that the eyepiece that you have?
