SCT and DSLR

Hey all,

First time Astrophotography poster, so be kind

I just purchased a Celestron Nextstar Evo 8 SCT and am very happy with the visual observing that it has given my family.

The plan is to do simple astophotography, yes I know that I need an equatorial mount to do it properly, just dimming my toes here :-P

I have a T adapter that fits my Canon 6D and the telescope, however Im having a focus issue that I cant out, hoping someone in here can point me in the right direction.

When using the DSLR and trying to focus, I can go from blurry to not so blurry, and back to blurry again, without transitioning through an in focus area.
It gets close to in focus, but never really gets there.

All I can think of is that the T adapter is not long enough as it is shorter that the ones that Ive seen on youtube vidoes for this telescope.

Anyone have any ideas?
