thanks Greg,
i know where your coming from with the SV90mm and ive taken a good long hard look at it but in the end ive just thought well the views through a short tube refractor dont really excite me no matter how sharp the optics are and 3k is a fair bit of cash (to me) for a scope that your only going to stick a camera in, even if it will produce superb images.
i guess what im after is a contradiction in itself being that id like some nice planetary views through the same scope id like to image through without spending big $$
where are all the 6" ED's
i guess the EON120 is still in front for me, even though it may not be classed as a premium scope it certainly seems a winner on the price vs performance front. some of the reviewers claimed to hit 300x+ before the image quality degraded and i wouldnt be pushing it that hard unless the seeing was superb which is almost never here
@renormalised, after first getting the QHY8 in my hands and having a good look over it the first thing that comes to mind is how solid it is.
not that im trying to defend the QHY but i dont get the same feeling from seeing the Orion version and i spot a problem almost straight away with the tiny cooling fan, anyone that has been into computer hardware will tell you that those small (40mm chipset) fans just wont last at all and when that goes you will have a passively cooled peltier (also when these fans die, its usually the bearings in them since they are farily high rpm, that will give you a lot of noise and vibration when the bearings grind around) as your probably aware a peltier could be best described as a heat pump, without sufficient cooling the peltier will do next to nothing especially when compared with a 2 stage peltier setup with a ~120mm fan on a huge heatsink or it could even have the opposite effect and heat the camera up since the heat is no longer being actively removed. i cant comment on the rest of the build quality of the orion since i havent seen one in the flesh but i can tell you that the QHY8 is built like a tank and no doubt will last for many many years.
