Dusting or mirror

[Obi Wan Ken00bi]

Whats the best way to get the dust of the primary? Dont want to disassemble the scope actually.

Pff stupid ipad autocorrect... Sorry for the title.

Rocket blower but tbh if its only light it wont make a difference to viewing

A high power, manually operated, blower works well but you need to get it reasonably close to the surface of the mirror (a few cm) which means taking the mirror / mirror cell out of the scope for a solid tube newtonian.

I'd just ignore it as it won't affect the performance. Shining a torch onto the mirror always makes it look awful so don't do that !

Unless the dust is effecting performance I'd leave it well alone. Primary mirrors can collect a lot of dust/muck before any drop in performance is inoticeable.

Ans what about using a static cloth or something?

[swamp thing]

No, never ever use any cloth to wipe your primary.

NO - please don't.     If the mirror gets badly crudded up then you can take it out and run it under a tap, possibly some soap flakes, then flush off with distilled water and put it somewhere safe to air dry (mirror vertically inclined).    Try to avoid touching the mirrored surface.As others have said unless really filthy don't worry as it will have very little effect on performance.Jake

Ok thanks for the tip, ill use a blower then, or nothing and leave it on. Thanks for the quick help! This forum rocks.

You'd have to have a seriously filthy mirror to affect viewing. Never touch the surface, the shiny bit can be 5 atoms thick. I've looked down some pretty dirty tubes, one had a decent collection of spider webs.

Haha, i guess mine's not so bad after all

the advice for dust on the mirror is sort of the same as that for a car engine noise that you cannot resolve. for the engine, just turn up your radio and enjoy the drive, for the dust, just don't look down your telescope but through it.
