@megabusa, the only clear threat voiced I that thread was from pick-n-pluck type foam where there is clear evidence of partial shedding, and suspicion of outgassing. I keep my eyepiece lens caps on so whatever effect there might be isn't going to touch the glass. My observatory is insulated so there is a minimum of temperature swings in the scope room and warm room. Once I get the humidifier and AC/heater in place I'll feel safer :-)

Yes I remember now, I'm losing my memory :idea: Like everything else I'm falling apart. :gramps:

Another BBQ cover also, but I might switch to bed sheets now.....seems easier to handle and gentler on the equipment.

All good ideas. We have a constant rain of fine dust.

Protecting the scope against dust certainly makes sense, but what do you do if the observatory is to be automated? My obs under construction won't be automated anytime soon, but the dream is there.... Always feel sick after staying out late. I seem to remember that some folks reported using dust seals of the hair brush type to prevent dust from entering the closed observatory. Does anyone have a source?

I use paint brushes where the rails enter the observatory. Not only does it help keeping dust, etc., out, when roof moves they brush any debris off the rails. :)

For the sides where the top w/rollers meets the bottom w/rails, I just used garage door bottom insulator strips.

You can buy long brush strips if you'd prefer that at McMaster-Carr.

I have the same solutions as Carol. Over 20 years no problem. I've had to replace the brushes once and a micro burst tried to pull the eye out of the wall for two of the turnbuckles (no other damage).

Carol,I like the garage door bottom strip idea for the gap inside. I was wondering though about the paint brush on the track outside? How does winter affect the brushes ability to work? I would think you have to brush the snow off the rails first before opening?

I simply give the rails a swipe with a snowbrush I keep in the observatory if the snow is heavy. If the buildup isn't heavy, the paintbrushes sweep the snow off nicely. You have to position them down on the rails to be effective.

Thanks Carol, I am going to give the brush thing a try. The stiffer the better I am sure.First, got to finish the build.

Tim, you're welcome. I think you'll find the brushes to work well.

Do you think that would work with a dome :question:

www.Memtechbrush.com I was trying to figure out how to add this to the bottom of my Dome , but because of the radius It can't work , Not flexible enough , But could be used on a ROR Obs

So it can't be used on a dome.

Here are some more flexible brush seals that might work on a dome.

I've always covered my scopes with Telegizmos 365 series covers. The observatory gets hot during the summer. Temperatures under the cover are 10 degrees cooler than outside the cover.

I used a large beach towel for the last 6 months. No spider webs, no marks on scope or mount. Highly recommended.

Well, I broke down and got a telegizmos cover. I just could not deal with leaving them uncovered even inside.

I use an original Orion Scope Saver (1997) from when the scope was new. It's lightweight, quick and easy to slip on and off.
Dust/pollen is the only problem with my dome. So the cover does a good job.
I do have a Telegizmo 365 cover that I used religiously before the OBS. But now it's just gathering dust in storage.

I use a beach towel draped over my dew shield to keep the dust down a little bit. That's fine when I'm there but I also use my observatory remotely. Taking the towel off remotely is easy, but I haven't figured out how to put it back on. Yet. So it just goes back on when I'm back there, which right now is about once a week.

I use a Desert Storm cover from TeleGizmos.

Keeps everything nice and clean.
