image quality will depend upon the instrument that forms the final image. <

The advice given is correct, and there is no need to be sarcastic. 
If the imaging instrument is very well corrected for coma and astigmatism, 
it will handle well large incoming angles created by the secondary. 
Also, if the field is narrow, the field correction requirement for 
the imaging instrument are comparatively lower. 

It is simple a good piece of information to know.
