This page is for user comments and information specific to the ETX-LS. Items that are applicable to all ETX models (RA, EC, AT, BB, PE, LS) will continue to be posted on the other appropriate feedback pages.

Mike here: Although the new Meade ETX-LS telescope is not scheduled to be available from Meade until March 2009, I thought I would start this feedback page to allow current and prospector ETX owners to chime in on their thoughts about the new model. If you don't already know about the ETX-LS, check out these web sites:

Oceanside Photo and Telescope

And before you ask, no, I don't have one. But I am interesting in learning more about this new ETX model. If the automatic alignment works as well as Meade instends, then it will bring a new level of technology to a wider base of amateur astronomers. However, the price is certainly not my idea of "Everyman's Telescope" (the original concept behind the ETX, and hence its name, when it was first released in 1996). But the price is not that out-of-line given the aperture and capabilities of the ETX-LS 6" ACF telescope.

If you have any feedback or opinions about the ETX-LS or if you KNOW you will be getting one when it is available, drop me a note at Lets start a discussion on this new era of the ETX.

Mike here: Even before the show opened, the ETX-LS was a CES 2009 "Innovation Honoree" (
Mike here: Meade has now posted an ETX-LS page on their web site:
I hope that battery life estimate is too low. Otherwise, most users will want an AC Adapter.

Hi mike, with the new LS scope, looks like you have you work cut out all
over again!! All the best with it.

By the way, do you know of any advise site other than M4, that deals
with Meade LX200 GPS scopes? regards Steve.
Mike here: There are some Yahoo Groups for the LX200GPS telescopes. I subscribe to the one at:

I wonder if this is a stand alone unit like the 497 or is it a dumb
terminal? I'd like to get one for my other 497 scopes if it would
work.Rick Blaisdell
Mike here: Good question. I have my doubts that it would work with older telescopes. I'm beginning to think it is a USB-connected AutoStar. I could be wrong though. I took a closer look at a high-res image of the ETX-LS and the AutoStar HBX cable still has the RJ-45 connector. So I guess it is still the same old connection method. But whether the AutoStar is a dumb terminal or a full computer remains to be determined.

I thought the attached picture might interest you. The central
obstruction on the new ETX-LS looks a lot larger than our ETXs'. I'm not
sure we're missing a lot! Pun intended ..

I considered a pre-order on this scope a few weeks ago, but decided to
wait for more info. Glad I did, considering the following info from website....

"The camera does not shoot high power images through the scope optics,
but rather takes complementary wide angle panoramas of what you are
observing through the scope itself. This helps to put the close-up
objects in context against the larger celestial background."

I think this is valuable information to post on your ETX-LS feedback
section, so others know its imaging limitations.  If I'd placed a
pre-order, I would be canceling it now that I know the facts about the

I have looked at the site OPT concerning ETX LS you mention an Autostar
II but they mention Autostar III. It looks a interesting instrument.

Regards Henrik
Mike here: Oops! You're right! The Anacortes site also says AutoStar III. I'll update the reference.

Coming on the heels of the ETX-PE, of which I have seen 6 and none of
them would point at all accurately and the MySky of which I have seen
three and all three didn't work, I have a bad feeling about the new

They had a winner in the ETX125 with Autostar and went downhill from
there.  Glad I have my ETX125 and none of the new stuff.

You should think about another Mighty EXT star party, hold it at
Farnsworth Ranch when they have the Messier Marathon, or possibly in the
fall at the same location.  Huge area to set up.
I'd help out!

Mike here: I'd like to do another Mighty ETX Star Party but right now, new home construction and then the observatory, are the priority!


Well let me know, as I said I would help with logistics etc.

That building a house crap can really be a PITA.  I have two friends who
stick built a house each in the last year and I got tapped for all sorts
of things.  At least the attic work on the A/C install was done in the
late fall.

Mike here: We have a great consultant who does a lot for us.
Mike here: More details are coming out about the ETX-LS. For example, it will have an AutoStar III instead of the AutoStar #497! See the updated page on OPT's web site for all the currently known information.

Still a big fan of the original ETX-90, but I thought Id' get your
opinion on the "ACF" optics on the new ETX-LS...

First, I have always considered the MAK-ETX line as "coma-free" as
demonstrated by the excellent images and sharp stars to the edge, using
eyepieces of the most basic design.

Secondly, the large central obstruction on the new ETX-LS bothers me...I
know it is of little concern for imaging, but will a drop in contrast be
noticed when using the telescope visually?

I know you have tried 8-inch compound telescopes with both standard S-C
and ACF designs, which has the greater CO, and which do you prefer for
visual use?

Kindest Regards,
Chris Brown (Maksutov fan)
Mike here: I didn't notice any change in contrast from the 8"SC to the 8"ACF. I suspect most users with most equipment will not see much, if any, change in the ETX-LS.

As a ETX-125 owner, I am greatly interested in this new scope.

If it is made as well as the ETX-125, it will be a home run. If it is as
problematic as the MySky, it will not be worth the money or the
headaches. I'll have a wait and prove it to me attitude that meade has
forced me to. If proven to be a quality, well made telescope WITH Apple
Macintosh support, I'll buy one. Anything less and I will go to a
competitor for my new scope.
Mike here: I too would like to see Mac OS X support. iPhone support would be cool!


Iphone/Ipod Touch support would be a home run!

hi mike im wondering if you have any info on the new meade etx ls acf

especially the lightswitch alignment system it all sounds too good to me
that a scope can align without the help of our own eyes

i currently own a couple of meade scopes 70at and the 125 pe can you
tell me if it would be wise to purchase this scope or stick to the 125
and my lpi

great site (and book using the meade etx very helpful!!!)

Mike here: I have no experience with the ETX-LS (obviously, since it has not yet been released). But check the ETX-LS feedback page. There are links to info there.

A bit more information about LightSwitch technology. Thought you might
be interested - heavy reading though!
