Re: Swiffer my primary mirror

Nick Anderson
 

Oh gee...now that's a somewhat controversial question in the amateur astronomer community! Around the time when I joined the BBAA this was one of my first questions to this forum, and I learned that there are incredibly varied opinions. While your Orion telescope manual specifically recommends cleaning your mirror once a year, it's nothing absolute. In my case, my first 3 months observing the Messier objects primarily from Sandbridge took an immense toll on my primary. In that short amount of time (although it's true I was averaging around an obsessive 15 observations a month that summer) the saltwater in the air over time managed to form a film on the primary, which fogged up the optics. Since then I've been a lot more careful about my scope and I think I've only cleaned the mirror again once. Dust alone is not something to be worried about! You should be fine for a while.

The instructions for my Orion XT8 classic dob tell me to remove the primary mirror and soak it soapy water and alcohol and wipe clean with cotton balls. Sounds like too opportunities to screw up, scratch and/or drop my mirror. I'm scared.

Isn't there a Swiffer for primary mirrors? HA!

That sounds like a good idea!  If we can schedule such a workshop, I'll volunteer to bring my scope for the demo.  (That's "demo" for "demonstration", not "demolition", as they use the term on HGTV.)

LeighAnne,

How long have you had your XT8 and how dirty is it?  I have had mine for 4 yrs and have not cleaned it.  You'll find varied opinions on cleaning, with some cleaning each year and others, like myself, avoiding cleaning as long as possible. One thing you will find agreement on is that it is easy to scratch your mirror and cleaning should be done carefully with a minimal amount of touching, wiping, etc.

If the only thing that concerns you is a little dust, then I would ignore it, as it will not affect your views. Many folks get concerned about dust on the mirror, especially if you shine a red light down your tube at night. No mirror looks good if you do that. Seriously,  I've been told an freshly cleaned scope will look dusty as can be if you shine a red light down a tube at  night and examine the mirror.

Finally, if you do think you need to clean it, I would try to arrange to have an *experienced* club member either talk with your beforehand, or even help you do it yourself.  If the latter, maybe we could even turn it into a workshop where everyone could learn the proper way to clean a mirror.

Good luck!

- Paul

Re: Swiffer my primary mirror

George Reynolds
 

That's right, Leigh Anne.  There is no need to clean your mirror routinely.  Only if it gets so dirty or spotted that it is interfering with the views at night should you attempt to wash it.  Bill is right.  I have had my 10-inch Dob for 8 or 9 years and have yet to clean the mirror.  One of these days I'll get around to it.

Fair Warning: I am bringing the twins!
We will have only their 6" scope; not enough room in the Camry for mine, too. If I could get a parking spot on th BW for my van, I could set up 2 or 3 scopes.

Re: Swiffer my primary mirror

I've had my telescope for less than 3 years. Today, I noticed some specks of dust/dirt on it and got very concerned that I'd have to take it apart. I haven't noticed a difference in optics at all (but haven't been using it for the past several months either).
Good to know I can just let it go for a while. I do keep the cover on it at all times. I guess it's not as bad as I originally thought it was.

I'm glad I asked first before taking it apart.

Thanks everyone! :)


Re: Swiffer my primary mirror

Roy Diffrient
 

You're right to be scared. Better to let it get crummy and do cleaning less often. Typically, you can't tell the difference in telescope performance, and the coating will last longer that way. When you must handle your optics, wear new rubber/vinyl gloves, and after you put on the gloves, wash them, to get rid of any talc on them. I don't like the wiping part of Orion's instructions -- It's really best not to wipe at all, but instead just let the detergent do its thing for an hour, lifting the dirt off. But if that doesn't cut it, if you feel you really must wipe, then apply no pressure at all. That is, drag a clean, wet cotton ball across the surface, turning the ball continuously, and replace it quite often, so that you're not dragging dirt across the surface. That method applies only the weight of a wet cotton ball to the coating. For bath water, a couple drops of Ivory Liquid and a spoonful of isopropyl alcohol in a quart of distilled water works -- Or I think there is a recipe for Dr. Clay's cleaner in the Yahoo files. Rinse with distilled water. To help prevent water spots, dab any clinging drops with a clean, untouched (no finger oils) paper towel, and again, no wiping. Others have good methods that may work too, but this is what I do, and my coatings are 20+ years old, still going.

Unless your primary is really dusty/dirty it does significantly reduce the views from your scope.  Best advice is clean only when necessary, and protect (dust caps) when not in use.  Dusting can be done using a gentle blowing (avoid or be very careful using compressed air dusters their propellants can affect mirror surfaces) I prefer a blub puffer/blower used on camera lens, just don’t hit the mirror with the tip.

 

When you do clean, always always always rinse in distilled water.  Some professionals suggest filtering all cleaning, rinsing solutions thru coffee filters.
