Scope mouldy after Sep-Dec under Telegizmos cover

[choochoo_baloo]

Unsurprisingly some light mould patches have formed on my William optics scope, untouched, under a Telegizmos 365 cover since late August. 

I suppose the water-tightness of the cover means that the typically damp autumn/winter in Britain means mould is inevitable for long periods outside?

I will now get in the habit of opening up to check more regularly now I’m back home.

Main question: how should I go about cleaning it off?

Thanks in advance.

Damn!!  Are the optics ok??

Well worth leaving a dew strap or two on low power to keep the moisture off even under the best of covers, and air it every so often too.

Hi 

I would worry more about the optics. Any fungi growth there could damage them.

Get some Baader wonder fluid , as it has an anti mould formula for optical use

Hope this helps

It's not good. The WO GTF aluminium lens cap was jammed on. Took a lot of twisting to remove. Nice big mould colony on one of the inner surfaces of the triplet objective - looks like a petri dish!

I'm annoyed with the Telegizmos cover. Will be contacting FLO (suppliers) to find out about support. Gortex manage to make fabric breathable yet waterproof... I want to warn other British owners of Telegizmos 365 covers of this effect.

Looking into refractor servicing.

I don't think you can expect covers to do anything but keep the rain off, you're bound to get condensation on any metal surface, I put a mattress cover over mine under the scope cover and keep a puppy warming blanket running under that, also uncover it on any sunny days.

I dont leave my scopes out but for those that do u still need air flow under the cover. Some people who keep the scopes in a shed use a 100 watt light bulb so it doesn't free either

Lesson learnt 😕

Actually the triplet element seems to be mostly condensation - it's steadfily shrunk since been in teh house. Though some faint hazing beoynd teh shrink codesation, this could well be mould traces still. Can anyone recommed Orion Optics servicing? https://www.orionoptics.co.uk/telescopeservica.html

They're obvs a top drawer optical manufacturer, so it they can't service a refractor, I don't know who can!
