Cameras and diagonals

[GrampyG]

What are the advantages/disadvantages of connecting the camera via the diagonal rather than 'straight through'?

Thank you

Any extra glass or mirrors can only take away from the image quality.  Best avoided by using a suitable extension tube.

If you are using a refractor or Mak without a diagonal you will see a correct orientated image in either the viewfinder or live view screen of the camera.

The biggest problem is that a diagonal can not hold a camera very well so the whole lot is liable to rotate causing the camera to go crashing to the ground. A two inch extension is much better.

Surely the image would be vertically inverted without a diagonal? Going through the diagonal corrects the vertical direction and leaves it left-right reversed?

That apart, totally agree it’s better without the diagonal, extension tube is the way to go.

The scope would act exactly like a camera lens which too gives an inverted image if you looked through it, the electronics in a DSLR flips it to provide a correct image on the live view screen and the prism in the viewfinder does the same.

The beauty of this is that I can use my WO scope as either a 400mm  camera lens or 320mm ish with the FF/FR for wildlife imaging...same with the Mak although at around 1200mm f/l is only useful for imaging ants on a far away wall
