Attaching a DSL-camera to Skywatcher Explorer 150p

[Yd4l]

Hi! I bought a skywatcher explorer 150p a few years ago, and I lately checked out equipment in order to attach my Nikon D-80 to it (the aim is to take pictures of the moon). I bought a sky-watcher T-mount adapter 2 and Doppler T2-adapter for Nikon F. The only problem is, I do not quite understand how to actually take photos with the equipment I bought. When I have attached the camera to the T-ring and further attached this to the adapter, the camera is unable to focus. I suppose I should use one of the lenses that came with the telescope in order to be able to take photos, but I am unable to understand where I should attach the lens as it does not fit the adapter. Does anyone else here have any tips/advice for me on how to use this correctly? :)

Does your telescope have a 1.25" focuser or the 2"/1.25" crayford ?

It has the 1.25” barlow lense
