Quote:One last thing, can you please give me the website where i can order the stuff, because i couldn't find one.. (i hope they ship outside of US also.
Quote:Hey there, my name is Guy and I have the celestron cpc 1100 with the xlt coatings, and recently i tried to remove fingerprints on the corrector lens with a cosmetic cottonball soaked with water, but it just made more markings of dried water on it.. i think the problem was that i used regular water and not the distilled one..So after the long story, what do you recommend me to do? and how should i clean the corrector lens if it has the BrightStar XLT coatings? (you can see the picture i added)Thank you so much,Guy

Quote:And one more thing Stacy,does your lens cleaner suitable for the xlt coating?

Quote: I can't wrap my head around where the idea that modern coatings are some extremely fragile thing. My items look just like when they were new, unless I personally did something foolish with them.
Quote:Same thing as always:Blue (original) WindexWhite (no lotion) KleenexCanned airDust the corrector with the canned air. Clean with a tissue wetted with Windex. Swab outward from corrector. Change tissues frequently and dry with a clean one. Dust any lint remaining with the canned air.This is what I have been doing for 35 years with uncoated correctors, multi-coated correctors, UHTC correctors, and XLT correctors. Never hurt a thing and my clean correctors are the envy of my friends..
Quote:From Celestron: "If dust has built up on the corrector plate, remove it with a brush (made of camel’s hair) or a can of pressurized air.Spray at an angle to the lens for approximately two to four seconds. Then, use an optical cleaning solution and white tissue paper to remove any remaining debris. Apply the solution to the tissue and then apply the tissue paper to the lens. Low pressure strokes should go from the center of the corrector to the outer portion. Do NOT rub in circles!You can use a commercially made lens cleaner or mix your own. A good cleaning solution is isopropyl alcohol mixed with distilled water. The solution should be 60% isopropyl alcohol and 40% distilled water. Or, liquid dish soap diluted with water (a couple of drops per one quart of water) can be used."
Quote:1. Windex is a household cleaner that contains ammonia.2. Ammonia has alkaline properties and is corrosive.3. Putting corrosive liquids on your corrector plate could very likely damage your coatings and/or the corrector itself.
Quote:1. Windex doesn't contain ammonia, and even if it did, that wouldn't hurt your coatings.

Quote:It is unclear on the "ammonia" that is in Windex. The manufacturer says it is "Ammonia D," but is reluctant to describe exactly what that is.
Quote: Ammonium Hydroxide (From Johnson & Son website)Ammonium Hydroxide is commonly referred to as ammonia and is found in air, soil and water. Many consumers use it at home for cleaning and laundry. It’s a cleaning agent that removes dirt, and it can also be used as a pH adjuster that alters the pH of a product to improve stability. Every formula has an optimum pH to make it work best. For example, a formula that’s more acidic works better for soap scum removal. Its opposite, a formula that’s more alkaline, might be more effective at removing grease or greasy soils. We use pH adjusters to make sure we achieve the best pH for a particular job. Also, the pH of a formula can affect how long it lasts within a container – for example limiting its tendency to rust in a steel can. Household ammonia has a strong odor; by using Ammonium Hydroxide in combination with other ingredients, we can achieve the same cleaning results while using much less ammonia.

Quote:Dear Stacy,Thank you for contacting Celestron Technical Services. We spoke a few days ago and you mentioned that on a forum it was mentioned you can use Windex to clean your corrector. Can you provide us with the forum that indicates the information? Windex is not used to clean the corrector. See links from our knowledgebase.http://www.celestron.com/c3/support3/index.php?_m=knowledgebase&_a=viewar...http://www.celestron.com/c3/support3/index.php?_m=knowledgebase&_a=viewar...
