I had upgraded my mount to an EQ6-r so decided to replace my 8 year old skywatcher 200mm . When fully equipped the Mn190 weighs in at 16.3 kg (scope, Altair guide scope and camera, Atik383 mono and filter wheel) so was a bit concerned about tracking as the kit is set up and taken down each session. The scope holds its collimatiion and the mount tracks well.
I have added a skywatcher remote focus kit to the standard focuser and it holds the camera and filter wheel firmly but you can override the tube friction if you push too hard when inserting the camera.
The field of view is slightly larger than my previous scope. I have added a lifting handle to make handling easier so I don't have to bear hug it when lifting it on and off the mount.
