lads, this only just started happening the last couple of times using my bintel 2x barlow. Prior I wasn't getting this problem. Not sure if it's focal train issues or something out of whack. I have cleaned the barlow and front element of the refractor. Haven't touched the bolts where the front element or lens is locked into place of the eon 130. I looked through the barlow while still attached to the canon camera at out of focus lights and couldn't replicate this. Any thoughts?

notice the lines in the out of focus stars top pic then they change as focus gets sharper then at focus there is a spike one side of the stars.
