Loose dirt on mirror Meade Lx6

Hi,

I recently started taking CCD pictures with modified web cam and picked up some particle spots in the frames (same spots on all pictures) I presume that its dust on the mirror of the scope. How do I fix this?

Nope, the dust is on the webcam sensor. The telescope mirror is too far away to influence the image. Most modified cameras have no window to keep dust off the sensor's cover. A camera lens cleaning brush works fine. Also, some cameras have 'hot pixels' that are defects in the sensor, and are permanent.

The rear mirror is very dirty. can it be cleaned?


Hi, yes of course the mirror can be cleaned, but you need to be extra, extra, extra careful not to scratch because this will determine the clarity of the images you observe. Start by removing the mirror. Use latex gloves and handle only the edges. Next, place the mirror into a warm slightly soapy bath to loosen the dirt. Rinse off the grim using a clean water bath, do not rub with your hands! If there are still particles visible after the rinse, then repeat the steps again, this time let soak for longer. Lastly, once you are satisfied with your results, wipe the face of the mirror with acetone and replace. Hope this helps.

I have an older ETX Astro Telescope or ETX spotting scope. A small rectangular mirror has come loose in the main body of the telescope. It appears undamaged. Is there a manual that shows me how to place...


This is a known issue with the older ETX scopes. You can use silicon sealant or a small amount of hot glue -- and just put the mirror back on it's small platform.

However you might need to disassemble the rear of the scope to do this. See this web site for instructions on disassembly.

Does it have a name on the scope? If it has a MIRROR in the bottom it is a REFLECTOR.

If it has a lens on the front it is a REFRACTOR. Look on Meade's manual web site under the header REFRACTOR or REFLECTOR for one similar to your telescope.

You can take short exposure images or a video movie using a web cam. Then use software to pick the best frames and stack them.

Here are several web sites to get you going.

Meade 10" LX6: I need to find what color wires connect to what pins in the Encoder Junction Box connector. Appears that several may be broken and I don't have a schematic. Does anyone have the schematic...


This is a very old LX6 telescope. I have never seen a schematic on the internet. Except for these articles:
http://www.astromag.co.uk/pdfs/lx6.pdf

This person may be able to help you:
http://www.onealwebsite.com/AstroPage/Telescopes.html

and this on page 33-34

You can also call Meade directly and see if they have one:
http://www.meade.com/support/index.html

Finally, you can post a message on the Yahoo LX90 and LX200 group and ask for help from either Dr. Clay, or Ron Sampson. Both of these folks repair Meade brand telescopes.

Where, and how much, can I find a 4.5 mirror for a Meade telescope


Meade will not sell you a mirror- most likely. Other than buying a brand new mirror which will be expensive try looking on Craigslist for a 4.5 inch scope for sale CHEAP and take the mirror out of it.

Here is the Meade customer service web site you can also try here:

Piece of felt covering mirror, is this suppose to be there?


Here is the manual for your telescope--

http://meade.com/manuals/TelescopeManuals/Reflectors/Meade%20114%20EQ-ASB%20manual.pdf

The mirror at the bottom should NOT be covered-- with felt? Unless this was something Meade did to protect the mirror from dust and dirt during shipping?

The motors have encoder wheels, that pulse when the motor turns, to tell the computer that everything is OK, and to indicate its position. If the wheel is loose on the shaft, then errors are indicated. A second point of error, is dirt in the wheel slots that disturb the sensing, or the optical pickup is bad.
