Subject:	lxd75 balance?
Sent:	Saturday, February 24, 2007 11:36:43
From:	Stephen Olson (stephen99@comcast.net)
Got another question foe the Guru. I think my scope is balanced. When I
loosen both locks it doesnt move, but i read on th LXD75 site at yahoo
that you can loosen the locks in any position and it shouldnt move? That
doesnt make sense to me. It also doesnt work when I try it. I have the
SN8. The only thing added is a telrad. DO you knoe where the weights are
suppose to be? This scope has such a learning curve for me. Its driving
me nuts. DO you make house calls? :)
 
Thanks for all your help

Mike here: When you unlock both axes the telescope should not move. If it doesn't you are sufficiently close to a good balance that trying to improve it won't make any difference. The exact positioning of the counterweight balance will depend on the accessories mounted on the telescope (finderscope, eyepiece, Barlow Lens, etc). However, in actual use I rarely worry about that. I just balance for my primary usage and go with that. I hardly ever reposition the counterweight with my LXD75-8"SC. I do move the telescope or backward in the craddle, depending on whether or not I'm attaching the Nikon D70 DSLR.
Subject:	Wireless Autostar

Does the wireless Autostar controller work with the LXD55 mount?  Do you
know of anyone who has experience with it?  The reviews seem mixed.
Mike here: If you mean the Wireless AutoStar II model, no. If you mean one of the Bluetooth modules, yes. See my comments on the "StarLink Bluetooth Wireless AutoStar Control" on the Accessory Reviews: Showcase Products page. For comments on the Orion Bluestar search the ETX Site for "bluestar".
Subject:	LXD75 SN8 AT needs collimating?
Sent:	Saturday, February 10, 2007 07:53:06
From:	Stephen Olson (stephen99@comcast.net)
I recently upgraded my scope from an ETX125 PE to the LXD75 SN8. Big
difference, but I seem to be having a small problem with collimation,
and I really dont follow what Meade says in the instructions. I have
included a link of the picture. DO you think you could give me a few
tips on hoe to correct it? BTW...Do you sell anything on your site? For
all the help you give everyone, it would be nice to help support.
 
Thanks,
 
Steve
Mike here: I don't have a SN model but the collimation should be fairly straightforward. You rotate one or more knobs or bolts until the collimation target is re-centered. Didn't get a link so don't see the image you mention. HOWEVER, are you SURE you need to collimate? If a new telescope (unless it was really banged in shipment) shouldn't need collimation. As to support, thanks! You can make a "pledge" from a link on my ETX Site (http://www.weasner.com/etx/pledge/intro.html).

I also Just donated 25! 
thanks again for everything.
Mike here: I don't see any evidence of a collimation problem in the image. I do see the "defraction spikes" from the secondary mirror mount. Thanks for pledge!
Subject:	Testing LXD75 Motors

Is there some way to test the motors if the hand paddle is not working?

From:	richard seymour (rseymour@wolfenet.com)
If you're only trying to test if they work -at all-,
try simply unplugging the Autostar, and then turn on the power.

The "unterminated" wires frequently inject "noise" into the motor
control cards, and the motors then make random short (or long)
motions.  The motions are usually unidirectional, rather than
back-and-forth.  Be sure to unclamp the axis locks to prevent
accidental hitting the hard stops.

have fun

Subject:	SC8 Misadventure

I thought that somewhere you said you had a Meade LXD55/SC8...

One of my friends has a Meade SC8 from which we can not get the
corrector plate free.  We'd like to remove it to experiment with a new
laser collimation "jig" we have machined.

Does anyone have any ideas on how to get this corrector plate off.  It
is stuck tight as a drum.  Even the glass won't release after removing
all of the retaining rings.
 
Any ideas?
 
thanks
Warp
Mike here: Yep, I have the 8"SC but haven't tried to remove the corrector lens. The OTA is (supposedly) the same as all the other Meade 8"SC models (LX90, LX200) so perhaps someone in those communities might know. Check MAPUG.com; perhaps the info is there.

And:

Thanks... Will do!

Thanks for your help.
