Shall I clean the secondary?

[rawhead]

The secondary on my 10'' newt is stating to look a little worse for wear. Not sure whether to give it clean?

Any comments appreciated.

I vote clean it, follow the guidance that involved running warm water and special cotton buds and it will be lovely until you then realise you have to climate the thing...

Most people will vote leave well alone and I would have been one of them until I removed both my mirrors and cleaned them.

I can tell you I was pretty nervous but afterwards I think back and say there was nothing to it.

It's easier then you would think and it does make a slight difference.

I vote if you are not happy with it, then clean it. Just make sure you can collimate afterwards.

Those specs are having no affect on the veiws the scope gives so I'd leave it.

If you're not sure.....it doesn't need cleaning

I'd wait until spiders call it their home, or slugs decide to take up ice hockey on it !!

I vote clean it, did mine and will do both the main and secondary once every 3/4 months, that seems to be the amount of time between dewing(viewing) sessions that it takes for mine to get fuzzy. I suppose I could get some dew straps to try and alleviate things, but I'm getting fed up of the cloud round here;). Also gets you into collimation quite easily. But follow the basic guidelines and do it carefully.

I vote trying a hurricane blower on it first, oh that wasn't one of the choices .

I had a few large flecks of dust on mine a while back and a quick blow shifted them all.

Spooky - just back from my garage where I cleaned my secondary - loads of dew marks etc on it

Of course, it didn't need it, but hey what's the fuss ? Just makes sure you use BPC Surgical cotton Wool and plenty of distilled water to rinse.

I'm dead chuffed with my very spangly mirror... Go on ! You know it makes sense

Thanks for the comments.

On balance I have eventually decided to.......

....... leave it for now

Take it back to John for them to clean it, best of both worlds hey lol. But at the end of the day do you want to be scared of taking your scope apart??? I am lol.

i vote get a hurricane blower i have one and it makes mine dust free as for cleaning it i would wait, i have taken my mirror out and given it a good blow over but i dont fancy scratching the finish on the mirror.

Got one. Gave it a blast before I even thought of anything else. Those bunnies are well dug in

As and when I pluck up the courage I will be doing it like this:
