Attempting to Observe Jupiter/Venus

Hey guys! I'm a relatively new amateur astronomer and tonight I tried to view Jupiter and Venus through my Celestron AstroMaster 130EQ. So, when I managed to get it in my scope this is what I saw:

Apologies for the crude ms paint drawing. The grey is the planet and the black is the structure of the mirror holder (as far as I can see). So, my questions are:

1) Why can I see the struts of the holder? I've observed the moon many times and it's never been in the way.
2) I couldn't get either planet into any recognisable focus, and ideas to why?

Thanks!

Not quite sure, new to this myself, what power eyepiece were you using? Did you use a barlow? To my untrained eye it looks like too much power.

Hi this looks like the 'scope just needs to be focused. If you are using a barlow or an eyepiece with magnification that is too high you wont be able to get it any better then that.

your eyepiece is not in focus, so turn that wheel to turn it in/out until you get focus. Maybe you cannot reach focus, then your distance to move it in/out is too small, but then your eyepiece is not suitable on your scope.

I've tried it with a 20mm, 10mm and 7mm eyepiece and all with/without a barlow lens and I got relatively the same thing.

have you tried focusing on the moon and then moving the scope to jupiter without changing focus,
On bigger dobs, you do get the vains holding up th secondary as spikes on the brightest stars.
