Now for something a little harder - a planet. A quick change of eyepieces to the 9mm showed Once the slewing stopped and the scopeįinished I peaked into the eyepiece. The ETX 70 AT is not as loud as the LX200 scopesĬome from the same family. Instead of “Tucson Arizona.” I decided to leave this setting I thought it was somewhat odd -ĭegrees or so to center each star. The setup of the computer controlįollowed the instructions on the hand controller (I don’t need no stinkin’ manual!). I borrowed a Bogen photo tripod to set the scope Night spent at Roger Tanner’s Rita Ranch observatory gave me the opportunity For a while I did not think I would get to use Moon and by the time the rains stopped (4 days later) there was too muchĪstrophotography. On my arrival in Arizona the weather was not the best. I need to try some parfocal eyepieces with this, After the first time I focused with the 9mm and slid the barrelįocus was obtained. Small complaint, they are not even close to parfocal! It took many The scope came with a 25mm MA and a 9mm MA eyepiece yielding 14x and 38xĪre not Naglers, they offer a reasonable amount of magnification to use Photography but the mount is not robust enough for astrophotography withĬontrol works on 6 “AA” sized batteries that are supposed to To allow mounting a camera in the back of the scope. Somewhat hard for my fat old fingers to reach in and turn this knob.Ī focus knob extension that replaces the stock knob and is very easy to The back and moves the front lens cell in and out to achieve focus. To those of you familiar with the ETX90 the telescope controls are no mystery. Possibility of tracking satellites with this thing. This, if it worked, would make it quite easy to find I must admit to some curiosity about the mount. Was fairly sharp across the whole eyepiece. Planetary scopes I suspected that widefield views would be quite nice.ħ0mm version and took a look at a light fixture out in the mall.ĭesign of this refractor showed color fringing on a bright light source. These scopes had an identical focal length (350mm) and while they would I took careful note of the 60mm and 70mm ETX style I was Christmas shopping up at one of the local malls when I drifted into It would take a lot of careful work to craft a scope of this nature. Possible to build an 8” or even a 10” carry on dobsonian telescope All of these had something going for them Researched many alternatives, 8” dobsonians, 4” f5 short tube I spent some time looking at the alternativesįor a “lookin’through” scope to use while my 4” refractor and G11 were working

This interesting little scope was purchased to provide an airline portable
