Inward focus

[Adidaz 29]

Hi just had my 10" Dob outside to take some pictures of the moon with my Nikon d5500 I recently bought a low profile focuser  I can see the moon through my camera live veiw but it blurred I need to focus further in and carnt go no more what are my option is this mean I have to move the primary  mirror because I would have clue and don't want mess around with things that Iam it sure with any suggestion s please

A Barlow would extend the focal point somewhat, that may help! or an extension tube?
If your using a low profile focuser, its my view that the focuser is shorter, closer, inside of the focal plane!  (could be wrong).

I imaged the Moon last night with my D5000, but with a standard focuser, no issue. 

Life's not so simple with astronomy, there's so much to take into consideration, and if its not one thing, it's another?

 Surely it's going to be more  blurred or un focusable  with an extension tube

Yes. If the problem is that you don't have enough inwards travel then your two options are either reposition the primary closer to the secondary or use a barlow lens to move the point of focus outwards.
