Nice HD image Marc. Looks pretty smooth to me and a similar field of view to what I got with my refractor. I reckon your could just do a bit more contrast work yet though.
Though that is personal taste.
I totally agree about your comments regarding how these scopes are made, but the important thing as you point out is the quality of the optics. Every GSO scope I have looked through produces very good results optically. It is the crap focusor and minor parts that can let the side down.
Nice work.
