Yes , the Mewlon's awesome 1/20th wave guaranteed mirrors ,, Strong Japaneese build quality
yes , my old M210 gave the best 'Refractor' like images from any reflector I have ever looked thru up to 800x on a good night , but ,, yes there is always a but and here it is for me .

Diffraction spikes , , for me I would personally put up with CA on a good Achromat ( iStar ) , hence I sold that awesome scope and now have an easy 96% of the Mewlon's quality of Luna / planatery views in my sweet C9.25 XLT starbright that I have now , and zero diffraction spikes
