Moon aperture comparison

[Radman40]

Thought it may be fun to compare my WO 72mm Megrez refactor with my OOUK 250 mm f6.3 Newtonian to see what the difference in resolution may be.  I tried to keep everything as equal as possible e,g, focal length, image acquisition parameters, processing etc. 

You can certainly see a difference but I thought it would have been more marked.  The seeing was 'average' at best so I guess the newt was not operating at its full potential.  

The target is the Theophilus/Cyrillus/Catharina trio which was well paced last night.   Both scopes are easily able to resolve 8km craters but the the 72mm cannot resolve the 4km craters in Mare Nectaris which the 250mm is just managing (though it may not show in this compressed image).

Makes you wonder that for the average guy like me, who enjoys a bit of back garden astronomy under light polluted UK skies, a modest aperture scope will go a long way to . Certainly cheaper and easier that lugging large aperture scopes and their mounts in and out of the garage.   I hear so often on SGL that the best scope is the one you use most often.   I think when I get too old to haul the Newt around I may settle for a 102mm refactor.  

I shall repeat the exercise under good seeing to see how things stack up.
