I have no doubt from reading these forums that high level imagers are truly enjoying this hobby in the amateur sense. I also have no doubt that visual observers are also enjoying this hobby for all the reasons they always have.
There was a story in the Sydney Morning Herald this week about a business that still services typewriters because there are some people who still like them better than writing on computers. It wouldn't surprise me if there were mathematics enthusiasts who still use slide rules. That doesn't mean we shouldn't use computers.
As far as our hobby goes, the choices are, well, astronomical
. This website couldn't exist without modern technology; it enables us to communicate our results and thoughts across the world on a minute by minute basis.
So go for it whatever way you like to do Astronomy. There is no ethics to ponder.
