    Default Meade ETX 80 First Light



    Finally got the new ETX 80 "we' got for Christmas out and gave it a test run. I purchased a combo deal that came with a 20mm and 9.7mm EP, a storage bag for the tripod, and purchased the hardshell case separately. The only knock I have with the outfit is the tripod. It is very light and VERY shakey. I will be looking for something a bit heavier for the scope to sit on. We viewed the moon, almost full, and was almost too bright to bear looking at for any length of time, but views with the 20 mm were good, the 9.7 distorted the image somewhat (atmospheric conditions?). Next took a look at Jupiter, three moons visible and could see the bands, but I never got the feeling that I was truly "at fine focus". The scope had a lot of vibration (due i guess to the light tripod) while trying to focus. Checked out the Orion Neb. and it looked very nice with both provided EP's.

    I need to work with the motor controls during the day before I give the goto a test run, but it was fairly easy to pick up the objects we view manually. Looking forward to really giving this scope a go when time allows. Looking for a camera mount for my point and shoot Lumix (does short video as well). Any suggestions appreciated.

    Congrats on the new scope. They really are nice scopes for the money and are light enough to carry around. I like mine pretty well but it does give a purple tint to bright objects. just be sure to train drives if you haven't already before you start alignng.

    Congrats on your first light ...Sounds like you had a blast ....As far as the tripod goes , You could try hanging a small weight from the center to steady it . Or you could make an adapter plate for the scope base and use a heavy duty camera tripod or surveyors tripod with an adapter plate .. If i am not mistaken , there used to be a company that made an adapter plate for this but i think they went under a few years back ..This site has some great ideas for the Mighty ETX scope as well ...

    Congrats on the new telescope! You can get filters to take care of the chromatic aberration on brighter objects, but a moon filter will do in a pinch. I use one on my 102 mm refractor and it works quite well.

    Check out some of the AutoStar tours on weasner's site. Do a Google search on autostar tours and they should come up.

    I have an ETX60. When I want to view an object at high power I find that the motors add too much vibration to allow me to see clearly. To get rid of this I center the object I want to look at and then hold down the enter key for a few seconds. It beeps when I let it go and the motors stop. This is the sync feature. From there, I can slew the scope around without the motor jiggle.

    Congrats on the scope!

    I too have an ETX 80. And while it is small, and somewhat limited, it is very fun for me.

    I suggest getting a finderscope of some kind.

    Tho it is large, I have mounted a telrad on mine. It makes things much easier.

    And, like has already been said, train the drives-complete instructions are in the manual....just make sure that when you are done with the 'AZ' drive training portion that you click the down or up arrow button to move on to 'ALT' drive training.

    The manual isn't super clear on that one..and the sequence defaults to doing the AZ over and over again.

    I will add, that doing the 'calibrate motors' function on startup will pay you dividends as well.

    "high precision" slewing is also well worth the time (and is where a finderscope comes in the most handy.

    Default re: ETX 80

    I purchased my ETX 80 scope in October. Within two weeks, the autostar controller failed, and Meade promptly replaced it. Two weeks after getting the new controller, one of the latches on the tripod broke and Meade told me to ship my scope for a replacement. A month later I got a new scope, but weather conditions prevented me from using it. On the first opportunity to use it, autostar worked really great as I had trained the motors and found that it works really well with stellarium! Unfortunately, the optics was not that good, the focuser was a bit flimsy and there was a glazed spot on the optics. I called Meade and they are replacing this scope as well. Now, I purchaed a small yet firm little table I plan on mounting the scope to. It will also serve to keep and hold my laptop and cables. I will post pics once I get it all setup.
