I am just curious if a quality 70mm refractor will show the small disc of Uranus.
I previously owned a 60mm F15 Unitron, with ortho EPs and it showed all stars with a aerial disc similar in size to the planet, thus making the identification impossible.
Last night, I used my 80mm Vixen (F7.7) Apo with a Fuju orthoscopic EP, and its color and disc was unmistakable at 50x. When I used some basic plossl EPs, I needed 83x to be certain.
So, I am seeking personal experiences about what was smallest-sized, quality refractor that was used to see and identify the planet?
