Forgot how to attach DSLR to telescope

[MartinF]

Oh well... I guess I´m not really a beginner at astrophotography. But when you can no longer remember how to connect the darn gear, this is the right forum section?

I have the TS Photoline 80mm f/6 refractor, a TSFLAT2 corrector and a TSFLAT2A adapter. I also have a Canon EOS T-ring adapter plus a whole lot of distance rings and stuff.

I also have a TS Optics 0.79x reducer/corrector.

HOW do I attach my Canon 550D DSLR to the telescope? For the life of me, I can´t remember or make it make sense when googling. Can anyone help me? It can´t be that difficult, right?

The gear:

Let me state the obvious: T-ring goes into the Canon bajonet, FF adapter is screwed into that for the proper backfocus, TS-Optics FF screws into it, that goes into the 2.5" to 2" adapter that must have come with your telescope - though you did not reference it. All parts have 42 mm threads on both sides except the T-ring outside thread, right?
