Good thread and good plan, Mario.
You could record short hand held videos through the eyepiece using your phone, then process them as you would a video taken with an astro specific camera. This works well enough for lunar or planetary and will teach you right from the start one of the main elements of AP: data processing
BTW dobs make awesome terrestrial scopes if you can live with the tilted view. I've used my 8" for birding several times and the detail visible was insane.
