    Default Have a 15-20 year old ETX 125, thinking about upgrading.



    I live in DFW, a sinkhole of light pollution. :-)

    Got the telescope, got the good tripod, got the set of seven eyepieces with the ETX 125 Observer. I haul it out once or twice a year for eclipses, planets, moon. It does what it does OK.

    Family situation changed, so wife and I getting to travel more in the camper. Spoke with a guy with an 8" Meade at a star party in Texas recently, starting thinking about upgrading. Did some research here on LX90 v LX200, not sure I need the LX200.

    • Seems like my existing tripod and eyepieces would work
    • I am interested in GPS feature for quick setup (location and clock)
    • I do a little telephotography with a pretty good Nikon DSLR with good sensor
    • Not sure I want to carry anything much larger or heavier than the 8" for this
    • Would like brighter, sharper image for planetary viewing, might start to look more at DSO.



    Thoughts?

    Hello and welcome to the forums

    For size when travelling the 125mm ETX is hard to beat. A 8" though nice is considerably bulkier if storage is at a minimum, also the ETX tripod will not be stable enough for a 8" SCT if that was what you were referring to.
    GPS is a useless accessory as you can get all of this information from your cell phone or a computer already. The GPS modules do nothing to enhance accuracy of alignments or speed them up.

    I agree with Gabby about the tripod. When it comes to viewing objects I find the LX90ACF a treat : You can't beat a Az/Dec mount with a reliable goto system for enjoyable viewing. The GPS only makes setup a little easier because you don't have to type anything but it does not make it more accurate, getting the OTA completely level in all directions is the most important thing. When it comes to astrophotography the Az/Dec mount is not ideal and you would have to add a wedge to make it a polar mount. I have a Nikon D5300 and because it has a 60mm infocus (distance between sensor and lens mount) you need a focal reducer with a working distance that is more than that(the GSO 0.5 is 53mm) , also if its a ACF you cannot use the Meade 6.3 reducer/corrector you need the Lepus 0.62 from Optec and its $200.

    I too live in North Dallas, horrible light pollution here. I have owned and sold every scope you mention. The LX-90 is a perfect size travel scope for visual work. Much better than the ETX, though the focal length isn't a big deal, the light gathering is. The LX-200 is a great scope, was my first real scope I had the classic, and as far as I know it's still running just fine 20+ years later. The LX-200 is quite a bit heavier though so bear in mind if you need to haul it around a lot. Optically the LX90/LX200 are pretty much exactly the same optics, and use many of the same accessories. I'd go for a 2" visual back and good diagonal, like a Tele Vue or Stellarvue and then some good eyepieces. I love my Panoptic 22 (probably the most used EP I own) in all my scopes I have now or have had in the past, from 6" to 20" The Nagler 17mm and Meade UWA14mm & UWA8.8mm (old series 4000) plus a 35mm Panoptic and I'm set, it's not often I can use any higher power than the 8.8mm though I do have EP's going down to 2.5mm I add in a good visual filter too something like the UHC for bringing out detail in nebula. You'll probably have power from the RV in most cases, though a portable battery if you set up to far from the RV would be nice, as would an observing chair (comfortable position) makes all objects better. Depending on where you are travelling to, dew heater and or dew shield, I use a flexible one as the metal/rigid ones make the scope heavy, and they don't store easily - especially when space is at an issue like in an RV.

    I've sold probably 150 LX-90 scopes and 500+ LX-200 scopes over the years, never had any major customer complaints on them, a lot of them ended up coming back to us because the owner wanted to go even bigger. Only once or twice did I have someone go the other direction, and that was due to age and the weight. LX90 series are a lot more easy on setup time and hauling. The 10" not too bad, the 12" & 14" were simply a pain to move travel with and set up, plus they could take a long time to cool down (Believe me I've owned all of them).
