Its a good question and one that was partly behind my own search. I saw the eVscope and wanted to see if EAA could be achieved for me in my situation (light pollution on the rise, running out of low hanging fruit targets in my garden), without real added complexity (setting up, learning curve etc) but at lower cost and with wider pathways for the future.
I don’t own a laptop and have no plans to own one any time soon.i have my ipad/iphone and they are both quite powerful if exploited well. I don’t want to teach myself software that only plays nicely on Windows etc and that may be free but takes effort to learn the basics because its not set up to be a supported product. I don’t want a “set up” that takes effort to set up!
The answer so far for me is that no alternative exists imho and partly because as soon as you start EAA you realise your goals change. You realise you want to see more depth, wider skies and sharper images and this drives you towards bigger, more complex set ups but also routes to better experiences in the longer term.
So, most alternatives are compromises. To be honest the more i look into EAA the more i realise eVscope has tried to make something play “nicely” in all its bits and pieces every time its used. But at a big price. Perhaps it will be a forerunner of a truly “killer” system in future years.
As an alternative, Asiair Pro is perhaps the best route forward in many way - all in one package (in theory) but in my limited experience it does not always “play nicely” as advertised across the components. Still a work-in-progress.
So, closest equivalent to my mind could be a Starsense-enabled 6” GOTO Evolution, an asiair pro, an asicamera, sky safari and an ipad. But its not what i need for my own journey going forward because, once you start down this rabbit hole...
