    Default Eyelash gunk! / cleaning



    OK... Since I've started to use eyepieces that you have to certainly get up-close and personal with meaning unavoidable touching of the eyepiece with your eyelashes at times.

    My new 6.7mm and 11mm ES82 eyepieces are sufficiently low eye-relief as well as not not escape this is seems. I guess the deposits though aren't anything too worry about too much and can be left without cleaning often? - I mean the coatings must be pretty damn resilient? Just curious what other people do or bother with.

    I've never bothered to clean my 10mm BCO ever and noticed this certainly now has a reasonable amount on the eyepiece. These types of eyepiece (ES82) seem impossible to clean with a lens pen because the shape (concave lens) and/or is not suitable plus the size of the lens (BCO 10mm) which is fairly small obviously... For these I'd have to attack with the Baader wonder fluid and fine cloth - not something I want to do often and still awkward.

    I gave my Skywatcher EPs a go over with the lens pen last night though (pretty much a bi-yearly thing) and now they look shiny shiny. Got to love that lens pen!

    I use a Lens Pen on my ES 82º's. I give them a good once over about every month. It kills the time during cloudy nights.

    I start off with the brush end of the Lens Pen and knock off any debris, then apply a little breath fog followed by the business end of the Lens Pen. Pristine glass then!

    *gasp* You BREATHE on your EPs?! Monster! from what I understand they're more durable than a lot of people think, but be careful if you unscrew the barrel to get a closer look at the underside, because I'm pretty sure something extra came loose when I did that on my ES 70 which is why it fell apart. I do puffer bulb-brush end of lens pen-'business end'. Great tool, and I found it for cheap at a local Best Buy

    Yup, good ol' breath fog works wonders. Maybe I'm just caustic.

    Fortunately, the 82's do not require the barrel to be removed, and seems to be quite tightly fitted anyway. These are a much different animal compared to the more simplistic 70º 25mm. I do clean my 25mm in the same manner, though it doesn't see much focuser time unless I'm at an outreach event.

    Not sure how you use the lens pen (is yours the Celestron one?) on the 11mm and 6.7mm, Bryan - I gave it a quick go last night As mentioned the lens is quite convex and the lens pens is too.. so in the middle the surfaces don't touch.

    And NOOOOO!! Dont unscrew the eyepieces lol. ( this is the voice of experience )
    The eyepiece never recovers from being taken apart. I opened one of mine. Now it always has dust particles that I cannot get rid of floating around inbetween the glasses. It was a cheap eyepiece so not the end of the world. But my others just have external cleaning only lol

    Aye... and in some the little lens's will fall out if you unscrew the barrel It should never be required to clean that part anyway!

    I buy my Lens Pens from Wal-Mart here in the US, about $10.00.

    Yeah, on the convex glass, the Lens Pen doesn't fully contact the glass and the edges of the Lens Pen's "scrubber" are relied upon. But, with the breath fog present, that provides (to me) a visual cue that the entirety of the glass is being contacted and cleaned. Seems to work great for me. Having the entire 82º series, some of these are convex while others are concave. Either way, same process in my case.

    Just give it a little exhalation and see what you think.
