Hello Paul,
If you use the telescope with the reducer then you should be good with an M48 x0.75 (T-ring) to Canon EF/EFS adapter since that reducer is specified as having a M48 MALE thread to connect to.
If you are using the telescope WITHOUT the reducer then you also need a nose piece which screws in to the aforementioned M48 to Canon T-ring. That assembly ( nose piece and M48 Canon EF Tring) goes in to the telescope focuser tube which in your case supports either a 1.25 or 2 inch interface (according to the specs you listed). Since your telescope supports a 44 mm image circle l would suggest you use a 2 inch nose piece, which threads on to the T-ring and then is placed in the focuser and is held in place by the focuser thumbscrews.
You may find these nosepieces sepately or even with the relevant t-ring on say ebay or purchase via an astronomy website such as Bintel or Andrews Communications. You may also choose to buy 2 Trings: one which could remain on your reducer and one to use with the 2inch nose piece.
Best
JA
