I have been messaging with a few other owners of the Japan made C102 refractor, and we thought it would be nice to start a thread about these achros. In my opinion, I do not think you can find a better optical performing 4 inch for the money. These are outstanding, and you can get the OTA for around $300. Reading the reviews on excelsis telescope ratings ( they rate about every scope ever made)
these scopes have about the highest ratings from owners that any other scope they list, nearly all 10's. I know there may be better performing refractors out there, but you have to pay dearly for them. I have mine on the astro tech voyager mount, with the long vixen wooden legs, and the astro tech mount extension. This removes the painful task of bending over, which makes it so easy to use.
I can go to 275X when we have a pretty descent night, and still have sharp views. If taken care of , these scopes will last a lifetime.
