For basic cleaning:
- Use compressed gas or compressed air to blow off loose dust and large particles. …
- Use a cleaning solution to gently lift off any remaining dirt or smudges. …
- Use the solution to wet soft, plain tissue or cotton balls for larger optical surfaces or cotton swabs for small parts like eyepiece lenses.

How do you clean coated optics?
Only use compressed air, reagent grade alcohol or de-ionized water to clean plastic optics. If an optical coating or substrate is unknown, err on the side of caution, and use de-ionized water and mild dish soap to avoid damage to the optic by any harsh chemicals.
Why is my telescope blurry?
Too high a magnification is the leading cause of most telescope images being too blurry to be classified accurately. Any magnification above 200X may make images unclear in certain atmospheric conditions. The magnification on a humid summer night will not be the same as during a winter night.
Can I use acetone to clean camera lens?
Do not use acetone. Acetone is a great cleaner, but, when used on camera lenses, it could have adverse effects on the plastic and paint of the lens barrel, as well as the optical coatings. Again, do not use acetone.
How do you clean a dirty mirror?
Combine one cup water, one cup vinegar and a teaspoon of dish soap in a spray bottle. Shake gently to mix. Apply the solution directly to the mirror and let it sit for a few seconds. Wipe the spray on the mirror away with either a microfiber cloth or newspaper.
Is it okay to clean camera lens with alcohol?
Yes, you can use alcohol to clean a camera lens. I recommend using 99% Isopropyl Alcohol diluted with distilled water at a ratio of 50/50. Some variants of Isopropyl Rubbing alcohol have less than 99% and include other agents that leave sticky residue on your lenses.
Can you use isopropyl alcohol to clean glasses?
On our own eyeglasses and sunglasses, we use a solution of 70% isopropyl alcohol (aka: rubbing alcohol) diluted with some water and a couple drops of clear dishwashing liquid soap. This is the same solution many lens labs use. Spray the solution onto the lenses and frames, buff dry with a clean microfiber cloth.
Does acetone hurt glass?
If this doesn’t work, the next step would be to spot clean using a solvent such as acetone, rubbing alcohol or mineral spirits. Use sparingly as these can be potentially harmful to the glass. Always clean the glass afterwards to remove the solvent completely.
Can you clean mirrors with vinegar? Mix one-part vinegar with four parts water and pour it into the spray bottle. Spray the solution onto the cotton cloth or directly onto the mirror. Before the spray dries, wipe the mirror from side to side or up and down with the cotton cloth.
When should I clean my telescope mirror?
The more you use it, the more likely small particles of dust are to find their way into your optical tube and get stuck on one of the mirrors. Usually, people clean their mirrors once every 5 to 10 years, but you may need to do it more often than that depending on the conditions of the air where you live and image.
How do I clean with acetone?
If there are ugly black scuff marks on your tile, concrete, or laminate floor, just pour a couple of teaspoons of acetone onto a clean rag or paper towel, and wipe the offending marks away. Then go over the area with a clean rag dampened in water to remove any lingering acetone residue.
How do I clean a secondary telescope mirror?
You will see many methods if you search around but the one I find most effective is soaking it in water with a bit of detergent, using cotton balls and ‘sliding’ them across the surface of the mirror without putting any force on the mirror (just the weight of the cotton ball), once your satisfied rinse with distilled
How do I clean my first surface mirror?
Gently wipe the mirror surface with the tissue to remove dust particles and finger prints. Do not wipe the entire surface and keep wiping to an absolute minimum to avoid light scratching. If done correctly, this method should not leave any streaks or spots.
How do you clean mirrors without vinegar?
Use Rubbing Alcohol to Clean the Stains
Take a small cotton pad and pour some rubbing alcohol on it to soak the pad. Then dab the stains on your mirror with a soaked cotton pad and rub the spot until you remove the stain. You might need to pour the rubbing alcohol more than once as it dries quickly.
How do you remove the haze from a mirror? Rubbing Alcohol and Vinegar/Glass Cleaner
Place some rubbing alcohol on a cotton pad and rub it on the stains. The alcohol dries off quickly so make sure you clean the stains quickly. Spray glass cleaner or vinegar and water on the cloth, if you spray it directly on the mirror, it can create tarnish marks.
What can I substitute for acetone? There are several alternatives that exist to replace acetone, including Replacetone, Methyl Acetate, and VertecBio™ ELSOL® AR. Vertec’s ELSOL® AR is a bio-based replacement for acetone, with a high performance and a versatile solvent blend for formulations.
What does acetone do to glass? As long as your mirror is made of glass, it’s completely safe to use acetone on it. On the other hand, if your mirror is coated or silvered, it might get damaged. Acrylic mirrors can be easily damaged by acetone, as acetone is a strong solvent which can eat through the plastic in acrylic mirrors.
How do you Defog a telescope?
Central heating radiator foil or an aluminised Mylar space blanket is great for this job. You can also wrap the band of a dew heater around the end of your finder, around the end of your telescope, or around your telescope a short distance back from the objective lens or corrector plate.
How do I know if my telescope needs collimation?
You want to see a diffraction pattern of concentric circles appear around it. Basically, this refers to circles around the star that might look a little wiggly. If the circles you see are not concentric, then your telescope needs to be collimated.
How do I keep my telescope eyepiece from fogging up?
3) If fogging is really tough to avoid, rotate your head and view with your head at such an angle that the exhalation from the opposite corner of your mouth is at or above the eyepiece height (because warm air rises). Never, therefore, breathe through your nose or exhale UNDER the eyepiece–it will guarantee fogging.
What does a telescope dew shield do?
Steve says: “Dew shields are metal or plastic extensions to a telescope’s optical tube. They serve two functions; to stop stray light entering the light path from oblique angles and to help keep dew at bay. At first, a telescope cools down via the movement of air until it’s the same temperature as its surroundings.
How do you stop dew from forming?
When in your room during the heating season, open curtains and blinds during the day to allow the sun to warm the room naturally and prevent air from being trapped against the window. Close them at night to decrease drafts. During the cooling season, do the reverse. Run a fan to help circulate air.
How can I make my telescope better?
By placing an extension tube between the Barlow lens and the eyepiece, you will increase the magnification of a telescope by two three or more times, depending on the size of the extension tube.
Why can’t I see planets through my telescope?
Planets are small and far enough away that they will never fill a significant portion of your field-of-view, even at you scope’s highest usable magnification. If you want to see a larger disk, you need to use a higher power eyepiece.
Why are Barlow lenses blurry? It’s because you’ve exceeded the practical limits of magnification for your telescope. These are determined by the laws of optics and the nature of the human eye. As a rule of thumb, the maximum usable power is equal to 50x-60x the aperture of the telescope (in inches) under ideal conditions.
Can I use acetone instead of isopropyl alcohol?
Acetone will work fine. The whole point of using isopropyl is that it evaporates quickly, leaving no residue. Acetone is used in every lab for cleaning glassware for the same reason. Just don’t drink it.
