lenspen and dust blower - is it safe?

[ak47]

is it safe to use a lenspen and a dust blower ( the typical type you find in camera shops) to clean my eyepieces\corrector-lens\diagonal-mirror\etc ?

thanks

I wouldn't suggest using a LenPen on a corrector-lens. But a brush that's super-fine like the LensPen is perfectly alright - after giving the area a blow with a blower like you pictured above. I do use the LensPen on eyepieces - after making certain it doesn't have any debris embedded in it. Others think not. But always do anything on coated optics very gently. A major mess, like a greasy fingerprint, requires actual cleaning protocol be used.

Be careful -

I always use a lenspen on everything even sensors the real advantage I found was that a grease mark could be removed with one gentle stroke  previous attempts using fluids just spread the mark all over which then required many minutes of rubbing to clear it.

With care you can use a lens pen, but I too prefer a soft fine haired brush after blowing. You must not use it on a mirror.

Blower first, followed by soft brush, followed by blower works fine for most debris on lenses, eyepieces or sensor.

For greasy marks like fingerprints then Lenspen I find works best on eyepieces or lenses but would not use on sensor.  

Sensor cleaning requires dedicated cleaning kit.

By now you may have gathered the lens pen is ok on most optics except your mirrors. Have a look at the Baader Wonder Fluid kit, used by a good many forum members for general cleaning of most optical surfaces, see FLO top of the page for details
