I may as well post these... these are the system charts for the Takahashi FSQ-85EDX scope.

System charts explain all of the combinations of crap that you have to screw on to the end of the scope to achieve whatever you want to achieve.

The scope is just a series of glass lenses within a tube... and they focus at a precise distance from the end of the last bit of glass... so when you want to do something you need to get the final bit, the eyepiece or camera, a perfect distance (within a fraction of a millimetre) from the end of the tube.

The scope publishes this distance, but most scopes (and all refractors) come with system charts too... and if you want to add reducers (reduce magnification) or extenders (extend magnification), these take different lengths to achieve their function and thus require different adapters to still reach the perfect focus.

And so... system charts.

The way to read these:

• Green are the outcomes I want to achieve... visual planetary and deep space, as well as imaging for deep space.
  
• Pink are the things already included with the scope.
  
• Yellow are the things I need to buy to walk the system chart and achieve the outcomes.
  
  

So yellow things become the shopping list.

There is an error though, 33, which is TKA02154 T-Mount DX-WR, this isn't needed... as I'll be using a ZWO camera and not a DSLR, and so there I needed the Takahashi OU073 adapter to attach the ZWO camera.
