I am working on a mobile observatory and have started with a 6x10 enclosed cargo trailer. I first installed some nice walls, insulated the ceiling and installed a roof air/heat unit. I then built in a front cabinet and am working on a flip up table/desk to run alongthe left side and a fold-away bed on the other. I am powering it with 2 group 27 batteries and a large 2.5kw inverter. Since I plan on setting a GOTO scope on the outside while I sit in comfort on the inside I am building a weather tight box on one side to house six 12v power plugs a 110v outlet and a USB and RS232 port to easily connect the scope to the trailer. On the inside is a couple of computers to run the scope and do the imaging work. The lights are LED to conserve power and a Night Vision mode of RED LEDs makes it great for leaving the back open and allowing fellow observers in.
If anyone has already built something in this same small foot print, please send along some pics and helpful information. I will include some links to the early construction of the trailer and will add more later. This small size will allow me to position it along with other observers and not be in their way. Plus it is a great place to hand out hot coco!

Ceiling is just tall enough. Everyone keeps asking if I am going to put a big screen TV here. LOL.

Hi again, Bert! I just Welcomed you over in Beginners, & asked if you could go into more detail, and really glad you found us here in Observatories! 
Your Observatory trailer is fantastic!

Thanks, it is a big project in progress but will be well worth it when done. I am hoping to have it completed within the next 30 days. I'm saving up for solar panels to charge the batteries. I am trying to keep it as "Green" as possible and leave very little carbon foot print.

 You've put a lot of work into it!
BTW, I mistakenly said I Welcomed you in Beginners, when it was actually Equipment

wow that 1st photo from the bottom really had me for a minute there, the scale is ambiguous I thought you had some 200 amp circuitry there : )

It is a 200amp 12v breaker you are looking at. The inverter is 2.5kw so at max load it could pull 208amps. The box on the right is 110v with a 20amp breaker for the Air/Heat and a 15amp for interior and exterior outlets. The wires on the left are all 2gauge 12V stuff. Soon a Converter/Charger will be installed above those connections to easily charge the batteries while on AC and will switch the trailer automaticaly to batteries when un-connected. I am trying to automate everything as much as possible.

Bert, I really like the setup, what I can see your doing a top notch job.
Please keep us posted on the progress, I have been thinking about doing the same thing and I can't see a thing I add to it.
You have or are contemplating all of your power needs no matter the location, AC, DC conversion with possible solar power in the future, way to go.
I don't know what your location is but if bugs are a problem you can always add some bug netting for the doors.
I'm curiuos to see how you will handle the storage of the scopes and mounts and such.
I'll be looking forward to updates, keep up the good work.

WOW....where have you been all this time? ;<)
I have been looking ALL OVER THE WEB for this type of implementation without finding it.
PLEASE post any and all photos you want to...it will be appreciated by many.
I am very impressed with the workmanship and design...very well thought out.
I look forward to reading more about this venture.

Could you also include where you have sourced some of these mods?
Like the fold up desk and bed?
I see a metal flue in the right front of the trailer..ventilation or cable port?

I will put in more detail as I progress. I hope this project will encourage others to do the same. It can be as fancy or as plain as you like. I think it will be a great unit to take to star parties and with its open design will invite curious guests in to view the wonders above. I am working with my local Astromony club here in central Florida to make it available for their educational out-reach programs. Even on the poor seeing nights, the computers in the trailer will be able to scroll thru images taken by the club members to help encourage others to join the hobby.
The curved aluminum corner panels are there as decorative pieces that give the small trailer a deeper illusion. I did not want to feel "boxed-in". Along the inside ceiling edges will be cable tracks to act as finishing pieces and will be functional as well. It will allow me to run new wires, fiber etc, in the future without tearing out walls.
I am very much an amateur at all of this and am questing knowledge just like like everyone else. Hopefully some of the forum members can quide me along in my build.

I would suggest including a screen door on the back of the trailer. One could velco it on, allow for rolling it up out of the way when needed and have it so one could totally remove it when not needed. It would help with ventilation.

I would also recommend you search the "Equipment" group at this site using the word "trailer". There are some very good discussions that you will find very helpful as to some of the previous implementations that other members have done and the design tradeoffs that were made.

I would also recommend detachable leveling jacks for the back of the trailer so one can detact the towing vehicle and still allow the trailer to remain level.

I would also like to recommend you combine your posts into one, to keep the thread managible.
Thanks!

Yeah..sorry about that. ;<)
I just am really excited to see this type of observatory showing up...I have spent days looking for this type of implementation out on the web.

Hi Bert
Welcome to CN and the OBs forum. If I read your posts correctly, your trailer is going to be a mobile command post, with the scope(s) outside, mounted on the trailer or free standing on the ground?
I've seen a few mobile Observatories here and on the web, including a couple with domes.
Here's Pier-Tech's effort Star Traveler Mobile Observatory This has a roll off roof
In CN's Observatory Articles section, Star Shooter Mobile Observatory Merlin's effort has a dome.

Your right, a better description might be a " Mobile Command Post ". The scope will be sitting outside of the trailer. I think with all the advances in todays GOTOs, I should simply roll the scope out to solid earth and plug it into the trailer thru the special connector box I am building. This prevents the complex design of a supported trailer and offers more room inside the trailer for fellow observers to sit and enjoy. Also, If I want to use large DOB scopes in the future, I will not have to throw the trailer away and start over, I'll be able to connect it to anything that will accept a CCD camera.
So far, my friends call it a mobile power station for their scopes since it will have a large battery supply with external 12v jacks that they can hook into. 
Small enough to sit in the general area of other observers and their scopes.
