130mm F6.9 reflector: spherical mirror?
My first telescope was a Saxon 1309EQ; a 130mm, F6.9 reflector. I still have it, though use it less frequently now that I've upgraded. When I bought it, it was advertised as having a parabolic mirror; on the website, the box etc. However, I'm aware that the Skywatcher 1309EQ, a VERY similar scope with the same aperture and focal ratio has a spherical mirror. Since it appears that Saxon and Skywatcher both source their optics from Synta, it would be a reasonable assumption that they are in fact the same telescope, raising the question as to why one claims to have a parabolic mirror while the other has a spherical mirror.
As a result of this, I emailed Saxon and was told that while the scope used to have a parabolic mirror, the latest batch has a spherical mirror, though they could not confirm whether mine (bought early 2012) was parabolic or spherical. Soon after, the entry for the scope on their website was changed to remove the claim of a parabolic mirror, though some retailers have retained it. All a bit odd...
Does anyone know anything else to do with this? I realise Saxon scopes are rather more obscure than other brands, but I'd really like to clarify this, if only to know what to say if I ever sell it off (I doubt many people would be interested in a spherical mirror reflector). I'd also feel a bit cheated to have received a telescope with a claimed parabolic mirror that did not in fact have one.
