That's a good idea. Around here you get pollen, dust, dew, and rust spores

I was also told to bring in my EPs Not to leave them in the Obs .





I have mine in an excellent case that seals tightly. I have always left them in the dobservatory.

That's my idea of an observatory; not to have to lug things back & forth for viewing.


This is the same thing I thought, I started a Topic about this a while back and most people here at CN said to bring them in Not to leave them in the Obs, Something about Gases from the rubber that deteriorates , My memory's not that good , Maybe some one can post in and explain it again , But I guess if you control the Temp, leave the AC on at all times where it don't get that hot it's OK , Then it would be like inside your house. I turn on the AC in my Obs very rarely $$$ ,

I don't have air conditioning in my observatory; but have always left my eyepieces in my Doskocil air tight case. I must have missed that thread; as I've not heard of the rubber outgassing on the eyepieces. In my situation, I will continue leaving them there, year around; works for me!

Update: Here is your Thread.



Again, for the past 6 years, I've left all my equipment in my observatory, with no bad results. It's whatever makes a person feel comfortable, for me just unlocking the door, and not having to lug any equipment (except my tablet), is my comfort zone.

@megabusa, the only clear threat voiced I that thread was from pick-n-pluck type foam where there is clear evidence of particle 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 :-)

Also, folks with extreme ambient temps; sub-zero to +100F, had the most angst over deterioration of rubber, such as the eyecups.

Yep That's it , It's kind of funny that I'm fairly good on building stuff like Obs - houses & things , I'm a old Ship builder from S.Louisiana , I also built a lot of the Floating Docks in Lakes out West But when it comes to things like Out Gassing and Stuff like that, I don't have a Clue I ask Questions because of $$$ ,If I get it wrong I don't have the $$$ to fix it I just do what I'm told .

By-The-Way Thanks for bring back up that old Thread .

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.

It does a great job, and very inexpensive!

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

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
