Subject:	ETX finder scope

I appreciate your information on how to operate the finder scope on the
ETX90 and 125 Can this finder operate as a red dot without the scope
being powered up ? Does it have its own power supply or does it need the
power that operates the 'scope I wish I could use it like many red dot
finders that come with some of the smaller scopes I also have the atomic
time module, does this automatically set the scope up every time I power
it up?, and does it have it's own power supply? I purchased this module
extra for my ETX 90 because every time I powered up the 'scope I got a
time default weeks earlier and hours earlier.

Mike here: The ETX turns on/off the Smartfinder. There is a battery inside the LNT module but you need the ETX/AutoStar to use the Smartfinder. The LNT should remember the date/time, unless its battery is low. I don't have the clock module but I would suspect it supplies the correct date/time on power on. If it is not working correctly, check the battery and connection.

Now that I have my ETX125 back from the repair shop I was trying to use
the smartfinder I found that it is difficult to get back into the
original mode you were in to calibrate the 'scope after you call up the
smartfinder and have it operating. I wish that the smartfinder would
turn on/off totally separate from the telescope just like a lot of other
finders Can the smartfinder do this? Even after I have a successful
calibration I can't seem to get into the smartfinder mode without losing
my calibration that I need to view different items.

Again my heart felt thanks to you.

Mike here: Hold down the MODE key for a couple of seconds to bring up the MODE menu; there is a Finder option that lets you set some settings. If you just want to illuminate the red-dot press the 0 key on the handset to turn it on and off. You will notice that the 0 key also has a "light bulb" symbol.

I just wanted to tell you how much I appreciate your info about the
atomic clock device for my ETX90 which I ordered today ($25.00) this
should take care of my always needing to change the time every time I
use it ( although they say a lot of info is already programmed in it ) I
guess I can use this device for my ETX 125 also which should be arriving
to me after Meade repaired it for a faulty drive motor that rotated it
left  and right that I believe burned out after using their plug in

I also read about this in your ETX 90 feedback archives which I am also
thankful for knowing that this also happened to others

My advice is to always use a 12 Volt rechargeable battery or other
rechargeable device which should never be much over 12 volts output.

I also read about how a member mounted  his Meade My sky gun to a photo
tripod which I also did but took a 2" x 2" X 3/4 in. thick block of wood
and drilled a slightly smaller hole in the center of this block which
then allows the threaded camera screw to thread into the block I then
took (2) wide rubber bands and used them to hold the My sky gun to the
block and tripod.

Thanks so much for your expert advice.

I have a ETX125 and a ETX 90 that have smartfinders and there is nothing
I have seen in the instruction manual that points out what the plug jack
is for on the side of the smartfinder I didn't want to plug something in
and burn out the smartfinder (or worse the drive on the 'scope)
Can you fill me in on this,thanks very much.

Lou Welke
Mike here: Meade has an optional "Atomic Clock Module" that connects to the LNT/Smartfinder via that jack.
