Cleaning A Telescope Lens
Well, don't exist, information technology's more straightforward than y'all think!
If, similar me, your scope has been gathering dust in the attic for years, or in the garage over summertime, and then one of the best ways to improve its performance and bring it back to life is to clean your telescope'due south lenses.
In this commodity, I'thou going to walk you through the safest and nearly effective way of cleaning lenses on any optical equipment, (you can clean a camera lens the same style) only please pay attention to the rubber warning below:
Exercise Not Clean THE MIRROR(S) IN A REFLECTOR TELESCOPE!
Mirrors are a dissimilar beast, and I would recommend having them professionally cleaned.
Cleaning your telescope lenses is however a task that demands time, intendance and a decent, inexpensive cleaning kit, (like this one from Orion) but it can be done thoroughly and safely at abode.
OK, with warnings over, let's answer the question: How do I clean my telescope's lenses?
How to Clean Telescope Lenses
The lens is most important part of your telescope and, for that reason, it's vital to make sure that yous care for it well and exercise not damage it whilst cleaning.
Follow the five simple steps below in order to get perfectly clean telescope lenses and eyepieces.
A quick give-and-take of warning though:
Only go every bit far through the steps every bit you need for success.
For example: if your lens is really clean after step three, and so cease in that location. You shouldn't carry on through steps iv and five but for the sake of it.
Post-obit this communication means you lot'll get a make clean telescope lens but you'll minimise the take chances of damaging information technology.
There'south a brusque video at the bottom of this commodity which shows you each of the following steps for cleaning your telescope lens in action.
Step 1 - Protecting your Telescope Lenses
Considering even gentle cleaning can crusade minute scratches to the lens or its coating, the first step for cleaning a telescope lens is to foreclose them getting dirty in the first place.
Ever make sure to use the lens cap (if yous don't have 1, improvise: a shower cap or even saran wrap will do the job)
The lenses of your eyepieces need similar care, so make sure they are in a protective case (or even a resealable sandwich bag if you don't have a case)
Ironically, using the eyepiece is nigh likely to make it dirty, especially if your eye gets likewise close. Believe information technology or non, oil off your eyelashes gets left on the surface of the lens.
If you lot find this happens a lot, you might discover an eyepiece with improve eye relief (i.eastward. you tin can look through it from further away) keeps clean for longer.
Step 2 - Removing Telescope Lens Dust with Air
When there is no pick, the dirt has been left and you accept to make clean your telescope's glass lens, your kickoff pass is to remove loose grit from its surface.
Information technology's vital to remove loose particles outset equally fifty-fifty those tiny bits of dust can be enough to put small scratches into your lens or its coating if you jump straight into to scrubbing and wiping.
Your temptation will be to just accident the grit off, but...
Don't exercise it!!
Your breath contains a lot of water and getting spittle (frankly) on your telescope lens will do it no good at all.
The i thing you can exercise with your lungs (if you really want to) is to suck the dust off.
Yes, I did say 'suck'!
Cover the finish of your telescope above the lens with your fingers and suck in air from i side.
This will pull air across the surface of the lens and suck some of the dust off (and into your lungs) with no wet being deposited.
You may be pleased to learn at that place are a couple of ameliorate techniques which practice non involve using your lungs.
Any decent optical cleaning kit, like this very popular one from Orion on Amazon.com, will come with an air blower. Use this mechanical device to blow the grit off your telescope lens.
It works past sucking in clean air at one end and then, when you clasp the bulb, blowing it out as a jet through the nozzle terminate.
For me, the air bulb is more than acceptable.
Step three - Removing Telescope Lens Dust with a Brush
Working your way through these steps very deliberately will make sure you lot get the most effective make clean for the least risk of harm.
If y'all are satisfied with how make clean the lens is at present the dust has been blown off, stop hither. If not, it's time to remove the more than stubborn grime!
For this, you should use a very soft brush, like the one included in this telescope cleaning kit.
The brush should be kept in a handbag when not in use, and then that information technology doesn't collect its own dust. As an added precaution, use the air blower to clear dust off the brush after you've used it.
It tin exist helpful to combine this brushing step with using the air seedling from stride two to get rid of all the dust from your lens.
Step 4 - Using a Microfibre Textile to Clean your Scope
By this phase, all the surface dust and dirt should be gone - and it may well be time for you to stop cleaning birthday.
But continue lens cleaning with lens cleaner and lens cleaning wipes if there is evidence of fingerprint or eyelash oil on your lenses.
Firstly, have the microfibre fabric from your telescope cleaning kit and use that to gently rub the surface of your lens.
Do this dry - you practice not need to add lens cleaning fluid at this phase.
If there's still oil on there, or a water spot, then motion to a make clean piece of the cloth
You could well discover that this has left your lens looking perfectly clean and, if it has, then you should stop in that location and be pleased with a chore well done.
If, however, there is just a stubborn piece of grease that will non be moved with gentle rubbing (never rub your telescope lenses harshly), so it is time to innovate a bit of lens cleaning fluid to your telescope eyepiece.
Step v - Using Lens Cleaning Fluid
This is the final phase of cleaning your telescope lens and should only be completed if you take a smear which gentle rubbing with a microfibre cloth will not remove.
Whatever yous do, don't driblet the lens cleaning fluid straight on the lens, as it may piece of work its way around the edges of the lens and pull grime inside your telescope or eyepiece.
Use either a gentle circular move, or move from the middle of the lens to the edge to clean the glass.
Next
If you accept any grime that is particularly stubborn to remove, then put a drib of the lens cleaner fluid onto one end of a Q-tip and use that to directly get at it.
Recall to be firm but gentle, yous really don't want to scratch your lens drinking glass.
And that'south information technology - five simple steps to a very make clean telescope lens!
Telescope Lens Cleaning - a Recap
Yous now know all y'all demand to near how to clean a telescope lens.
Telescope lens cleaning is not to exist taken lightly, then here are some notes of caution:
-
Don't utilize this technique for cleaning the mirror(s) of a reflector - Don't have your lenses out of the telescopic or eyepiece to clean them (putting them dorsum together is difficult and liable to get wrong... and isn't required anyway)
- Just clean your telescope when you demand to - once a year for the main lens is probably fine, telescope eyepieces tend to get together more oil so may need to exist washed more frequently
- But, some contaminants can be harmful to the coating of a lens, such as some pollens and molds, so you lot should clean those off more regularly if they're a problem in your expanse
