Explore Scientific 80ED vs Evostar 80 EDS Pro


Recommended Posts

I am about to add a refractor to compliment my 127Mak and have short listed the Explore Scientific 80ED and the Skywatcher Evostar 80 EDS Pro.

My use will be partially as a grab and "see-between-the-clouds" scope and also as a good scope to start imaging, initially with a Canon 1100.  (Yes I know it will be a slippery slope with guidance, better mount, CCd, etc, etc - but hey, that's part of the "fun" - right!)

Ignoring price differences and the accessories that are included, the question that remains is whether the shorter focal length of the Explore Scientific (480 mm, f6) will be more sensitive to eyepiece quality etc for visual than the Skywatcher 80 EDS Pro (600 mm, f7.5).

I note also that the Explore Scientific uses a totally different finder mount and wonder if this limits choice significantly for guiders, etc.

Any other comments on the two scopes would also be very much apreciated.

f6 is well within the tolerance of most decent eyepieces. As to the merits of the es ed80 I wouldn't know for sure only guess. what makes the synta unit so good is its colour correction. How it achieves this is by having a slightly longer focal length. most of the ed80's I have read about which have shorter focal lengths have problems bringing the blue channel to focus causing bloating when imaging. i hear this can be processed out but it still doesn't appear to be something that's wanted. I am sure that the es ed80 is the same unit as the altair starwave
