Orion shorty plus

I have the Orion shorty plus barlow, a 25mm, 10mm, and Orion epic ED 2
5.1mm eyepieces. The scope is Orion skyview pro 8 EQ. I'm observing
Jupiter in this exemple.

If I use the 25mm eyepiece I have 40x magnification and Jupiter is
nife-sharp.When I set in the barlow lens on, I have 80x, Jupiter
become wery blur, unsharp.

I renmove the barlow and I shange to 10mm (100x) eyepiece or 5.1mm
(196x), Jupiter is whit both eyepieces wery sharp.I can see a black
dot and I think it is the shadow from one of the moons.

If I set in the barlow whit any of these eyepieces, Jupiter is
unsharp. So it seems that this barlow is a waste of money.

Any other expiriense?

We use an Orion Shorty Plus with a number of scopes, including 60mm and 75mm
refractors and 6"-10" dobs, with excellent results. Maybe something is
defective with the one you have.
