Question about Meade LXD55 AR5EC Achromatic 5 in f9 Refracting Telescope 05095503
I have the identical issue --- AND It did not have it when it was new. I was returning from a road trip, and heard the rattling cell get louder and louder in the back seat. When I got home, the retaining ring that keeps the doublet in the cell had almost fallen out. I GENTLY checked for lens damage and noticed that one of the three tiny foil spacers between the lenses had fallen out and was missing. I tried to fabricate one out of aluminum foil, but upon reassembly, I have symptoms identical to the ones you describe. No matter what I've tried, I still have the same symptoms. I'm getting close to giving up and sending the cell to Meade to service. I suspect the issue is that the dimension of the tiny spacers and when one falls out or is replaced with the wrong size, we get the symptoms.

This is an old problem but I will answer it--
The rattling sound is a KNOWN ISSUE with these scopes. It actually does not affect anything. The scope is what is called an acromatic refractor. ALL ACROMATIC REFRACTORS show color fringing around bright objects. You would need to buy an APOCROMATIC refractor with 3 lenses to get true color correction. These scopes are very expensive to buy.
You can also use a "minus violet" filter to eliminate most of the color fringing in that scope. If the scope cannot be collimated it should be returned to Meade.
