There had been a post created over a year ago about the benefits of an 80mm refractor over a 127mm Mak
but it left some elements out that were not discussed such as 80mm APO. The topic primarily involved discussion an 80mm achromat.
So I will try to be more specific. Since we are at the 102mm optics level the 102 APO is out of the picture as that definitely is in another league.
But what about comparing long and short tube 102mm achromats against the 127Mak?
I now only have a short tube (f/6.5) Celestron 102 with XLT coatings and I prefer it over my prior 127 maks.
For some reason the Mak levels out at about 120-130X when viewing the planets where I live. One reason is the limitations of the focuser. The other is my location. My refractor gives me more clear viewing and I can reach higher magnifications as well.
For those reasons I sold my Maks. Yes, I purchased one and was disappointed with it and sold it. Then I had regretted selling it and purchased another one but sold it too and replaced it with a SV 80ED. No regrets here.
Where I live and the EPs I use can have an affect on viewing experiences.
I only use the scope for visual and not AP. Unless I would be doing AP the achromat wins hands down overall-- planets, moon and DSO
