Subject:	HELP with AutoStar #497, Please..!!

I recently purchased a Meade 6" SN telescope with AutoStar.  But being
new at this whole backyard astronomy thing, I am having setting it up,
so that Autostar would work properly.

Would you offer any assistance, or any tips??

Thanking you in advance.

Mike here: First advice: read the manual, three times. Second advice: play with the telescope, following the steps in the manual indoors where the lighting is good and you can see what you and the telescope are doing. Once you are comfortable with setting up and using the telescope and AutoStar, then you can go outside in the dark without becoming frustrated. If you have any specific questions as you get into using it, feel free to write.

Not to soft soap you, but I feel like I should come clean regarding that
comment I made a while back about the LXD sounding like a washing
machine.  That was horrible hyperbole, muddy metaphor, soiled simile. 
After seeing it perform to the max last weekend I would say that it
purrs like a kitten, a loud kitten, but a kitten nevertheless.

There, that was some dirty laundry that needed airing.
Mike here: Some kittens purr louder than others! Same with washing machines!

A quick and easy trick for wind-effects
is to -unbalance- the system (just a little...
maybe a little more...)...

This way there is a moderate -load- in one direction,
instead of the easy-to-blow balanced system.
With an unbalanced system, the wind has to overcome
the unbalance before it can rock the scope.

After that, you'd have to dismantle the drive sections,
and tweak and tune the worm loading into the main gear.
Check that Meade didn't leave the worm carrier
(and motor carrier) insufficiently secured.
(the worm can NOT be heavily pressing against
the final driven gear... it must have a very
small amount of free play or things will grind
themselves down very quickly)

good luck

Hope all is well in your world. I was thinking about getting another
mount for my son. Its a clone of the LXD75/vixen mounts. It does not
have a motor drive. Do you have anything in your bag of tricks you might
be willing to sell? also do you know if its possible to make it a goto?

I just sent out my LXD75 SN8 to Dr Clay for a supercharge! I am so
excited. Any thoughts on his service? From what I understand its suppose
to be a very good service and worth the money.
Mike here: First, I am not a dealer so have nothing to sell. As to making the mount a GOTO system, checkout the Roboscopes Yahoo Group. Lastly, Dr. Clay's service is excellent.
Subject:	how to fix free movement over both axis?

Thank you for your site.

I have bought the LXD75 6 inch Newton. It works very well. Apart from
one thing:

There is a small amount of free movement over both axis. It is
negligible at small magnifications, but disturbing with small gusts of
wind and larger magnifications. The touching of my eyelashes already
causes saturn to jump up and down my field when using my 5mm Meade
series 5000.

Is this a fixable problem? I have tried to tighten some screws but the
manual does not support my search for the cause. Are there any more
elaborate manuals?

All the best from the Netherlands and thanks again.

Mike here: There are some tech tips on my LXD Site but I don't think these will address your concern. Do you have the tripod legs fully extended? If so, try reducing their height; that will increase the stabilility. Also, do you have the telescope properly balanced? That can also affect vibrations. What you are experiencing is not that uncommon, even with higher end telescopes.


Thanks for the valuable info. After some testing I decided to conclude
it is not a tripod issue.

It is the mount. After locking both axes (with or without attaching the
telescope) there is still some rotation possible on both axes. Say 2
millimeters in each direction.

Are there any experiences you can share with me? I hope tightening some
screws will solve the problem.

I hope you understand my decription. However fluent one is in a
language, some things are hard to explain.

All the best from the Netherlands,
Floris Hommes
Mike here: The locks are friction type so some movement is still possible, especially if you push on the telescope tube. But during GOTOs and tracking there should be no slippage. Is that what you are experiencing? Have you done a CALIBRATE MOTORS and TRAIN DRIVES?
