SpaceEagle Observatory (SEO) - My small window to the universe...

Recommended Posts

Hi to all,

I thought that it'll be nice to share some photos of my small portal to the universe...

General description:

-----------------------------

The name of my observatory is "SEO" - SpaceEagle Observatory.

The obsy is a 3m diameter Dome type which I bought at December of 2013. Before that I had a R-R obsy which I sold. The installation procedure, including a base/floor cement, started at at March of 2014 and after a lot of testings and emough changes at August of 2014 the first "real world" experimental tests started. At the same time my main remote operation room, at the basement of my house, was also ready. Until June of 2015 many more tests, equipment addendum and changes have been done to the obsy and finally it was ready for its first "serious" operational tests. Since then and up to now more required testing has been done to equipment, security, imaging, photometry and other sections of its "existence" and right now it's operational at 80% of its expected capabilities. 

After some few more scheduled changes and I hope to be the last ones... it'll be at 100% of it's full operation capabilities - if and when this very persistent bad  weather permits of course!

Here someone may of course ask... <<if it's a commercially purchased obsy then why did you put it in the DIY section ?>>

Well here are the main reasons which made believe that this was the proper section to post it  :

1. Even if the Dome (exterior part) was pre-builded and not designed and constructed by me I personally made a lot of changes and re-configurations to it as for example, the obsy base/floor was designed and build by me, I raised the rotating part by about 15cm using another type of wheels and by doing that I also reconfigured the rotation tracking system by adding special metallic rails made by me (DIY) . Another thing that I did was to repaint the interior walls in a black mat color (non reflective) and with a silver-gray color (also non reflective) the interior part of the shutter, also scheduled is the re-configuration of the whole shutter window position/limits. There are also many other changes and re-configurations which I made as for example : internal lights , mains power system, security backup power, autonomous emergency shutter closing system and others.  

2. The interior of my obsy including the pier, except of course the usual buys - telescopes, mount, focusing system, imagers etc, is in a big portion of it a DIY.  

I hope my desicion to put it here was right.   :smiley:

Ok, time to go to some photos and desciptions....

** For any of the commercial equipment I've used I wrote only a general description about it - this is a DIY section...
 

When all started....

Hi Stevp, thank you.

Nice! Great write up too. Just one question; are you sure you have enough screens? :D

LOL... no, actually I need one more  ! :smiley:

Seriously now, there are a lot of astro-programs, remote control ones, weather - my meteo station, and olthers... You can't go with 1-2 screens.

By the way, I notice you mention the PC for 'local control' in case needed. Does that mean that you don't use it through remote access to control the scope/dome from the control room, but you control all equipment directly?

Do you mind elaborating a bit more how you have set that up exactly?

Hi Chris,

Yes I indeed control everything "directly". I've made two different network servers (for extra security reasons), A LAN one and a WAN one which are both connected to everything (and when I say everything I really mean that there is nothing in and out of the obsy - weather stations, cloud sensors, SQL etc -  that can't be controlled/viewed/saved through LAN or WAN) through industrial all weather Gbit Cat-6 cables. These two different networks basically differ to the way they're hardware and software connected to all the rest equipment, as I said, mostly for security reasons. When I don't need a WAN connection the WAN server is off - most of the time is. The two LAN and WAN servers are installed in a separate dedicated Windows 2008 R2 main server which is located at my main operation room which in turn is 27m far from the obsy. There (in the obsy) are 2 Gbit server switches, 8 inputs each. The LAN control/work is done by 3 different PC's which are connected to the main server LAN network, the actual speeds on this network can reach an average of 120 MB/sec. The WAN control is done by connecting directly to the server's IP through DDNS. For speed, security  and "simplicity" reasons different WAN commands/controls over the obsy equipment is done in different ports assigned to different programs/equipment, even the main screens are assigned to different ports. It seems complicated and yes it is but only to make it  work, after that its simply clicking some icons on the remote pc/laptop. The actual speeds in WAN mode internally are the same, only the remote "command" speeds (which are of course depended on the internet connection speeds) are lower than LAN mode but in real world operation is hard to "feel" the difference. All the downloads (from cameras and other equipment) are saved, in the same MB speeds directly to a dedicated NAS Server for both LAN and WAN connections.

Hope I answered your question.
