It’s a Sky Watcher tube, with only a few accessories. When we bought it 3 years ago for my son, the shop suggested camera adapters either for Canon or Nikon. Having the D5100 I took the Nikon adapter without actually knowing, that it will be useful or not. I need to screw it in the place of the Barlow lens. So either use the tube for watching using any of the Barlow lenses, or take a photo using the camera. To set the focus there’s knob on the side of the tube. Moon is actually easy to photo, as it is bright enough. (If you look at my desktop posting, my wallpaper is a self made shot of the Moon, just made it blue because I like it so 
) The main trick is using self timer on the camera set to only 5 seconds (almost the shortest time my camera allows for self timer) . Just pressing the exposure button introduces so many vibrations, that otherwise ruins the image. I found 5 seconds is more than enough for those vibrations to attenuate, but short enough, that the target doesn’t “fly away”.
Next time I’ll do some photo of the equipment, but probably will send it you private
