New scope

[CedricTheBrave]

OK so I purchased my first refractor the Star Wave 80ED TR as a grab and go for camping holidays etc

arrived today looks really well made quite impressed with its solidity and the smooth focus tube etc and the nice case

now I did expect to stick my 17.5mm morpheus eye piece in and focus reasonably quickly on the moon tonight but no!

i can get focus if I hold the eyepiece about 3 inches out of the draw tube when its extended fully!

is that right? do I need an extension tube that big?

Are you using a diagonal? If not the. You will need an extension tube instead.

Maybe you're partially Japanese.  They tend to prefer straight through viewing of planets since any diagonal adds some scatter, decreasing contrast.

being closer to the ground would also help
