Cheap distilled water ?????

[spaceboy]

Hi All

Looking for a few gallons of distilled water. Would rather avoid the usually extortionate prices of Halfords so open to members suggestions.

Hi All

Looking for a few gallons of distilled water. .

For the whisky?

I got some from Tesco a while back, 1.5 ltr I think and much cheaper than Halfords

Not strictly "distilled water", but will this do?

25 Litres Deionised Water (5 x 5litres containers) Free Delivery | eBay

I bought a desicant de-humidifier for the observatory...it produces a good 2 litres a day. Maybe an expensive solution but it keeps the wife sorted for the ironing!

Not sure? It's going to be for cleaning a primary and micro fiber cloths.

Be careful the stuff you get from Halfords / Tesco's is Deionised water NOT Distilled water.

There is a difference

Try reverse osmosis water - available from places that sell tropical fish. Cheap and incredibly pure.

be careful there is de ionised and there is distilled, de ionised will leave streaks on optical mirrors

[spaceboy]

I did think it was distilled water only.

I'll vouch for this.

Why not approach your local Boots the chemists and ask if they will supply you some. That's what I did and when I told the actual chemist herself (not the counter staff) she said no problem and in fact allowed me to buy nearly a gallon of it.

Worth a try.

As Robbie I. has suggested RO water from your local garden/tropical fish supplier.

Have used it for 2 yrs on me Obsession always great results and no streaks or residue.

About £2 for five gallon.

I would second this, but it is used for marine fish.

To make your own, you'll have to boil your feed stock (tap water)

then condense the evaporate, not imposible but expensive, (gas/electicity consumed).

Moreover, do you live in a hard or soft water area, hard water by definition carries alot of silica, difficult to remove.

easier all round to buy it in.

(I wonder if Vodka would work? triple filtered i guess would be best, spose, but what to do with it once finished washing mirrors? )

Depending on how grubby the mirror is, pour the vodka back into the bottle and drink it. Lets face it............any bacteria etc in it is gonna be long dead before it goes into your system.

I AM joking of course. I would never waste good vodka on a scope mirror.

[Andy McK]

Well, what I could do, in the interests of science, is try several brands of Vodka from expensive down to the Li**L brands, document the results and report back..

Not necessarily that expensive. See this...

Solar Kettle

Seems like all you need is a black kettle, two tripods, a long pole and a efficient mirror. I am sure the first 3 items will be easy to find. The only problem where to find a nice shiny parabolic reflector with 98% reflectivity and dielectric coatings....
