Mirror dust cover for my 14.5" reflector
      #5075789 - 02/16/12 04:23 PM Attachment (148 downloads)

I've been looking for a long time for something to use as a mirror dust cover in my dob. I've searched through tupperware, planter drip pans, pizza trays, etc. and have come up empty. I was out shopping at an art supply store and as I usually do I look for things that were made for something else that can be used in my astronomy hobby. Well I didn't find what I was looking for but it started the old noodle thinking. My son, who is off at grad school studying music left me a voice mail. He's a percussionist which got me thinking about drums, drum shells, and finally, voila, drum heads. There was a Guitar Center in the same shopping center, I walked in and asked for a 15" drum head, my mirror is 14.5" and I thought a 16" would be too big. I got home this afternoon and took a look at it and it seems perfect, but I thought the edge would mark up the edge of the mirror. By chance the three mirror clips and posts were the perfect size to hold up the drum head about 1/4" above the mirror. All I need to do is put a knob in the middle to make it easier to put on and take off. Total cost: $14 bucks!

Don't know how some of you guys post more than one photo in a single post.

I mean it was a perfect fit. No mods at all.

Makes me want to reach for the drumsticks...

Maybe you should add a warning label on the front

Don't forget the drum case for the UTA.

Hi John,

I made a hat box ala Kriege that has protected the UTA since before the scope was finished. It's getting pretty beat up and a drum case would be an easy replacement if I don't want to go through the trouble of making a new one.

Very nice Jim. Much better than what I use.
It is an ice tub (as K-mart) calls it
I cut off the upper section where a pair of looped ropes were. Then added a larger drawer pull to the top center.

To post multiple pictures I upload the pictures to Photobucket.
I re-size them to 512 horizontal pixals with MS Paint prior to the upload to Photobucket.

Then I use notepad to copy the IMG Code.

Then when replying to the the forum, I copy and paste from notepad.
Usually to the bottom of my text.

I also do a preview prior to posting.
Didn't do that a few times and had to start over

Take care
Rick

Hi Rick,

Your cover looks good. I was wondering how you were going to do that. I still haven't seen your scope in person and I'm looking forward to it.

As far as posting the pics I'm windows illiterate even though I use XP at work. Never had good luck web surfing using internet explorer.

Jim,
I have had some practice doing this over the years.
Mainly from my Metal Detecting hobby.
In the early 90's had to learn some HTML (Hypertext Markup Language) in order to post text, color, pictures, etc.
Now a lot of it is built in if you know where to look.
That comes from using it, as in practice, practice

BTW, I am using a mirror shroud made from a piece of Cemetube. Similar to Sonotube, but made of plastic.

I brought a tape measure into Target and measured the diameter of all the laundry baskets and toy baskets. (People probably thought I was nuts and they were right.) I found a polyethylene toy basket that was just the right diameter for my 14" mirror. I cut the bottom out of it and it has worked great to keep the mirror clean. The photo shows the mirror cover and what remains of the basket, which I occasionally use when I need a small piece of polyethylene.

That great Dick. That's basically what I was originally looking for, but I had in in my head to use a lid, not cut it out of the bottom and use that as a cover.
Very resourceful.

Magnetic Plexiglass cover, attaches to my mirror cell, clears mirror by a 1/4 inch or so. Not a complete seal, but helps.

In place, rare earth magnets hold it VERY securely

If I wasn't an amateur astronomer as well as a percussionist, I would say "What a waste of a drum head." But as I am both I will say "What does the mirror sound like now?" Good idea though.

Waytogo, JimMo! I do the very same thing... amazing what can be cross-over'd to astro use!

In fact, i have two sons who are "percussionists" (aka "drummers")... so i might take a look at that idea myself. Seems like a *sound* concept.

While waiting for cool-down, you can play a few drum rolls while waiting for Saturn to rise.
