Morton i used to have a Vixen VMC110L and was nice and sharp on planets but that was about it IMO, good for terrestrial viewing though but the advantage with them is the open objective for faster cooling down time but the negative with them was difficulty in collimating due to glued screws that could easily snap if you wasn't careful and how it was a bit of a lottery to get one well collimated from Vixen so overall didn't do it for me and dd not have it long
