That is a bit odd, its pretty much what you would see through the focuser tube when there is no eyepiece inserted, or with just a Barlow lens inserted.
The glass seems to be awfully wide in that 25mm eyepiece. Whatever your problem is, collimating it almost certainly won't fix it. Really need
to see what you get outside at night.
