Subject:	Is the LNT Unit on the ETX PREMIER Upgradeable
Sent:	Saturday, October 28, 2006 21:56:19
From:	Phil Gayle (
I bought my ETX-125 PE last year and it's been everything I'd hope for
in a small scope, with one exception the LNT Unit Smartfinder. I wear
glasses and have a burn spot on the retina of my right eye, the two
combined make for a very difficult time using the "clear plastic" LNT
finder piece. I've noticed that the new EXT PE's have a different LNT
unit, that appears to have a frame around them that might help resolve
these problems of trying to align my scope. My question is can I upgrade
to the current models LNT easily? I know parts are interchangeable, but
I don't want to compromise my scope by trying to put a square peg in a
round hole so to speak. If it is not possible or reasonable what would
be my alternatives?
Thank You

Mike here: I have my doubts that the unit is swappable for the new model. So, if you want a LNT you have to sell your telescope and get the newer model. Alternatively, you could add another finderscope; see the Accessory Reviews: Finderscopes for some ideas.

my scope works great except every time I power it up it gives the wrong
date and time. I did a reset after changing the batteries, but still no
luck. It's only 1 and a half years old. The red dot is working fine.
Should I do a cal.sensors?
Thanks, Al Greene
Mike here: CALIBRATE SENSOR won't affect that. Did you change the battery in the ETX or the LNT? It could be the battery in the LNT is bad or not making a good connection. Does the AutoStar (MODE display) show the SmartFinder option? If not, then the AutoStar is not seeing the LNT. For more on troubleshooting the LNT, see the Helpful Information: Telescope Tech Tips page.
Subject:	Re:ETX90PE  -  Atomic clock update
Sent:	Friday, October 20, 2006 05:47:49
From: (
The LNT Module does not have any kind of internal WWV receiver to update
itself.  That function is provided by an additional accessory. However,
the oscillator for the internal clock is a high-precision circuit, not
just a simple crystal, so once it is set the clock will remain accurate
for a fairly long period.

Manually setting the clock using a GPS receiver or a radio station time
signal as reference will provide more than enough accuracy for almost
any amateur purpose.  If for some reason you need greater accuracy then
you will probably also have to set your location latitude/longitude
precisely.  StarGPS provides a means to set both time and position to
GPS accuracy automatically.

Hope this helps.

From:	Niels Peter Ditlefsen (
Using  WWVB,60kHz,Fort Collins,Col., is as we all know, not possible in

Any news as to when the LNT-module can/will be updated to work with one
of the Eurorean-radiostations (Rugby,England, or one in Germany or
Switzerland or ?)  ??

Beeing a "Newbei", I am deeply impressed by what I have learned from
your GREAT site.

Mike here: Haven't heard any specifics on a "universal" clock.
Subject:	ext 125pe and setting it up

From:	Stephen Olson (
I am totally confused. I cannot get any answers from the camera joint i
bought the scope at, and none are around here. Here is my problem in

I cannot get my scope aligned.

I bring it out on my deck and turn it counter clockwise to the end. I
choose 2 star alignment, and from that point i get lost. I am brand new
at this. It seemd that the scope is not pointing in the general area of
the stars based on the star chart i have.(MEADE)
Mike here: With the PE model you are choosing the wrong alignment method (2 star) or you are putting the telescope in the wrong HOME position before starting the alignment. For Auto Alignment the telescope is moved to the CCW hardstop and left there. For Easy Alignment (or 1 or 2 star) the telescope is rotated to the CCW hardstop and then back clockwise about 120 degrees to point to True North.
