Question: Can this be used in conjunction with a Meade ETX-90 series telescope that's equipped with an Autostar system?
Document: The "Celestron SkyScout" is one of coolest stargazing aides we have come across. We have never been able to get our Meade XTA90 telescope properly aligned to automatically find celestial objects and this has been a point of contention between my wife and I (she thinks I should be able to "fix" it).
I bought my SkyScout back in 2008 and I used it to aim my 8" reflector. It worked OK but I couldn't get much more than 2-3 hrs of use out of set of batteries even with the illumination set low. The GPS doesn't hold your last position in memory so you constantly have to wait 5-10 minutes for the system to reacquire or manually input this information along with the correct time. My old Magellan hand held GPS fixes it position way faster than this thing.
I got it back from Celestron, and haven't had a real chance to test the telescope slewing accuracy because of weather, snow rain, cloudy skies, etc. I have pointed it at Earth's Monn, and it says it's the Moon, so that's a good start.
I have to learn in 3D. For the first time in my life, I feel like the sky makes perfect sense. I see the constellations, and not just Orion. And I don't have to flip through charts or log onto the internet to find stuff. I can relax, laugh and cut up with the family, and still have a wonderful night of stargazing. (I also have a telescope, of course, and that's going to FL, too.
They've been asking me to get the telescope out so than can see even more.Pros:Easy to use. Very cool features. It always draws a crowd at night. It helps the kids learn astronomy in the best way I can think of - they get immediate answers questions while looking at the stars. That's way better than looking up info on Wikipedia any day.Cons:I can't see the display at night without my reading glasses.
The SkyScout works great and is super to explore the night sky and use in conjunction with my Telescope. I can immeduately identify or locate visible sky objects. I look forward to many hours of enjoyment with the SkyScout.
Used it the first day I got it, better than I expected. If you want magnification buy the telescope version.
Great little device - seems to work as it should though I haven't used it all that often yet.Can this device work with a Celestron telescope? If so, which? A telescope is my next purchase ... would be nice if this SkyScout would attach to a telescope.
It is GREAT! Have used it several times a week, off and on over several hours a night, since I got it a couple of weeks ago - batteries still good in it. Use it to help me align my telescope or know what I am looking at. Definately helping me learn my stars!
Pretty good item. Although, it should really be used with an accompanying telescope. You won't get any better view of the stars with it at all. What you will get though, is a great deal of interesting information about stars planets and constellations. From distances to mythology and other pertinent facts which are given in clear audio messages, or text.
Answer: I have a Meade ETX70 with Autostar. I find the included alignment system to be too time consuming. The SkyScout does a pretty decent job in locating my objects of interest. I then point the telescope to that area and fine tune the location until I have it centered. For the price I find it to be a worthwhile investment.
