RolandKol Posted March 26, 2019 Share Posted March 26, 2019 I would not use any baby wipes for it!!! They may contain oil! And I would not even clean such mirrors.... These little bits are not visible and have no impact at all Link to comment Share on other sites More sharing options...
Cornelius Varley Posted March 26, 2019 Share Posted March 26, 2019 I would not recommend babywipes. These might contain moisturisers that could possibly cover the mirror in streaks that will be hard to remove. The best advice I can give you about cleaning the primary mirror is don't clean it.

johnturley Posted March 26, 2019 Share Posted March 26, 2019 Ideally a mirror should be removed and immersed in water for cleaning, as I do about about once per annum with the mirror of my 14in Newtonian, trying to clean in situo will almost certainly leave smeary marks. If your mirrors can't easily be removed, then I would also advise don't try to clean them. John Link to comment Share on other sites More sharing options...
RolandKol Posted March 26, 2019 Share Posted March 26, 2019 Just in case you will decide to go for cleaning anyway... which I would not recommend, as yours is more than Clean for it's purpose: 1) use air initially... do not blow at it your self, but if you have a simple "Air Blower", use it first. 2) if dust has not came off after "windy procedures", - not sure how to clean it without taking of primary and secondary... if you take any of them off, you will need to Collimate the scope. Collimation of the secondary, - quite a nasty task.. and deserves the special place in hell!!!! 3) better, - do not touch! Link to comment Share on other sites More sharing options...

I would leave it. But if you feel compelled then, initially blow large particals off the surface then place it in some water with a tiny tiny bit of pure soap and agitate followed by running your finger tips gently over the surface. After this rinse with distilled water to prevent water marks from forming. DO NOT USE BABY WIPES! Adam Link to comment Share on other sites More sharing options...

RolandKol Posted March 26, 2019 Share Posted March 26, 2019 Just test it next possible night Look at the moon and check if you see any obstruction You will not! Of course, I do understand, - it is annoying to see the dirt inside, but believe me, you will have much more problems once you remove mirrors for cleaning. Simply ignore Link to comment Share on other sites More sharing options...
