My image scale is oversampled on both rigs
The 6” f6 newt with HEQ5 is 0.98 arc sec / pixel
The 8” f5 newt with EQ6-R is 0.88 arc sec / pixel
I’m imaging with a canon 600D with pixel size of 4.3um
One thing I forgot to mention, when I’m away down the coast at my dark site using the 8” f5 newt and EQ6-R mount I’m usually guiding on good nights between 0.75 and 1.20 arc sec error which is a huge improvement on the HEQ5 in Sydney where I can’t get below 1.20 arc sec error
The belt driven DEC on the EQ6-R must make all the difference plus better bearings and worm drive etc...on the bigger more expensive mount
