Thread: Is my scope ruined

Dang your right there @m01a1good spotting,

Thank you

Was about to say the same thing as m101a1, but thought I's better just read to the bottom haha... Dry internals is the key, doesn't matter if the thing is gassed on argon nitrogen or whatever in reality. Having no oxygen in the thing slows down mould or lense-spot growth, but it really isn't a 'must do'. As someone sugested, a large plastic bag attached to an argon welding reg with a small hole in one corner is a useful impromptu regassing setup. Wrap/roll the bag up to purge as much air out as possible, or even better attach it to a vacuum pump and suck the air out of the bag. Open the argon cylinder and let the bag reinflate with the purge hole pinched off so you only have mostly argon in the bag, then reassemble the scope. Job done!

helium balloon......will give you enough gas to redo it,,let it vent up into scope and then screw your bit back in.

Helium isn't a long term thing - it's notoriously hard to keep behind a seal as the molecule size is tiny. That's why they normally use argon as the purge gas - it's a much bigger particle size so 'stays put' in the purged device for a longer timeframe. As per - whether that's important to you for this particular unit is up to you!

Bin it, its a nikkon

And it had the added advantage of making it lighter😂

If it was a Nikon I definitely wouldn't be binning it. As it's a Nikko Sterling, then maybe.

You haven't lost any gas, as the gassed section is at either ends of the scope between the double sets of lenses...put it back together and focus the reticle by turning the rubber bit at the eyepiece end..

I think you are ok I don't think that part of the scope is sealed you would have heard the gas escaping when you unwound, Toss it in the fridge for a few hours
and see if it fogs.

Ah HA! We just discovered how covid got into NZ!!!
