The opening is 105x105 cm.
I found this number by setting up everything on the tripod inside, next to a wall. I then rotated the tripod until I had tested every position, while I released the clutches and moved the scope finding the point reaching the longest from center.
With my gear it's the top - front thumb screw on the finderscope, that is most likely to hit something.
I added ~5 cm clearance for it when the roof is closing and the mount is parked.
I suggest that you do the same. Set it up inside and measure the limit
As the powerline adapters will never work with the dew heaters I decided to make a hole for ethernet. I found what I need at a decent price, so that will be the best choice in the long run
My current setup Is an Oroin EQ-G mount with a f/4.9 native 8" newtonian. I wanted to be able to be remote with it, so I configured a 13A 12v power supply to drive everything. The 12v can be provided by the AC power supply, or by 12v car battery. The DC is fed into a fuse block housed on the leg of the tripod in the grey enclosure. This enclosure also houses an Intel NUC, the brains of the operation. It, of course, runs Linux/INDI, and if I need to, it also has a fully updated kstars/ekos/astrometry and everything else needed to run stand-alone on it so all it would need is a monitor
The scope has been updated with a moonlite focuser, a 60mm guide scope with a ASI290 camera, and the main camera is an ASI1600MC. I also have a cable that allows me to no longer need the hand controller. Everything is then remotely controlled from my office in the house. Wish I would have had this over the winter!
I am using the following INDI pieces; EQMOD, GPSD, WunderGround, Moonlite, Astrometry, ZWO CCD
12" pier with HDX110 using EQMod
ASI 1600 mono/color mains with ASI290MM in off-axis
ASI filter wheel
Moonlite focusers for the sharpening
AT115EDT w/.8x for the light
Fedora Linux, 100% INDI
I am amazed at all the observatories, and remote setups in this thread.
My setup is very simple in comparison, but INDI/Ekos make life much easier.
What I do NOT have:
- Autoguiding: my mount has no autoguiding port, and I don't want the weight and complexity (yet).
- Motorized focusing: I focus manually at the beginning of the night.
Mount: Celestron CG5 with the GotoNova 8400 Upgrade Kit, and 8401 hand controller.
Optical Tube: Celestron C8 with Starbright XLT, with F/6.3 Focal Reducer Corrector (1085 mm focal length)
Camera: Canon EOS 650D, with 2 inch adapter
Focuser: JMI EV2 2 inch focuser (it adds to the optical train length hence focal length is not 1280 mm). This is not strictly necessary, but it came with the scope package, and allows 2 inch accessories to be used.
All this is controlled from an old laptop (now a 2009 Toshiba Satellite A300, with Core 2 Duo), 8GB or RAM, and an SSD disk. The laptop has Xubuntu (XFCE) 16.04.3, with KStars and INDI from Jasem's PPA for daily builds.
The laptop connects to the home network by WiFi, and I use NoMachine to login to it and run KStars/Ekos from inside.
The battery pack was used for the mount only before I got a 110V AC to 12v DC adapter, and now everything is on regular house power using an extension cord.
Since I don't have autoguiding, I am limited to 30 seconds of exposure. I don't do stacking or postprocessing for many reasons, and the 30 second exposures are acceptable for now.
My workflow shuns eyepieces and visual work completely. Even focusing is done on the DSLR's LCD from LiveView at the start of the evening. I setup everything, do a rough polar align using the built-in polar scope, balance the scope, wait for something to focus on, then go inside and commandeer the scope from there. Plate Solving alignment is magic, and the killer feature for this setup. I then point the scope to targets and take one exposure to check everything is good, then create a sequence of 5 or so pictures, and let it roll, then move to the next target.
The tedious part is setting up and removal of equipment every night.
In theory yes. In practice, I don't think it would work well. This assessment is based on the fact that in Align, when selecting Slew to Target, it keeps trying for 10 or more times, and says accuracy is not met, and tries again. Don't know if it is gear or motor precision/backlash or what. The other thing is PEC. Even though the hand controller supports PEC, I tried it more than once and it made things worse, not better.
Might be worth a shot though. I also have a Celestron mount (CPC1100) and the slew-to-target align also takes a good few attempts and periodic error is terrible. Nevertheless I can guide to an RMS of about 1 to 1.5 arcsec using indi + OAG guiding through the handset.
On one session, I tested guiding with the main scope and camera first. In INDI, under 'Guider' I select the main Canon camera, and under 'Via' I would select the GotoNova mount itself, and then see how calibration is doing.
The result was a 'calibration failed' or something similar consistently. That what dissuaded me from taking this idea further.
V2 of my observatory is now installed but not live as I need a new weather station.
This time, the box is way lighter than the other one, lower design. The frame is wood, outer panels are aluminium.
It can be taken down in just a few minutes. It is quite a major improvement on the first box.
Any questions, fire away please.

Looking real nice Gonzo
I don't think this is far off a flat packed kit people would by.
If you are thinking of making a new MeteoStation, I have completed the box, and made quite a few updates to the arduino firmware and meteoWEB config (as it was not updated the last five years).
There are more options for customizing settings, and more checks to keep the firmware up. I also updated the libraries to newest versions with support for BMP180 among other.
They are all in my fork of INDI. I will make a pull-request when I get around to making the howto for it.
Thanks Jasem, yes it is a vast improvement from the first one.
Paul, I didn't use any velour, wood panels painted black only.
@Magnus, I will contact you via pm regarding the weather station.
So for the new box I have spend many hours thinking about the new design. I know my first box had inspired quite a few out there. Magnus was too I believe (correct me if I'm wrong there), I saw his box and pinched the idea of having the linear actuators further apart from each other.
My first box had many flaws, for example the camera would hit one linear actuator, I had a leaky lid, the wood side panels did shrunk, the micro switches for the lid were inadequate. It had too many screws, too much wood, too many angle brackets.
I watch quite a lot of youTube videos about wood tenons, cutting wood, gluing wood etc...
The frame is wood, properly cut square, minimum amount of screws (I used probably a 10th if not less than the old box), wood glue was also used (damn this glue is super strong once fully dry). The inside panels are plywood, probably 4 mm or so, they are not structural.
The outer ones are aluminium composite panels, SUPER strong and SUPER lights.
Each panels are secure by 6 screws only at the bottom (3 each corners) and only 4 screws at the top. It takes 10 min max to dissemble the box.
The alu panels are actually stuck to the wooden frame using 3M vhb tape, go watch some videos about this tape, got to see to believe it really.
I had to design it with constraints in mind: had to "fit" the allowed/allocated space on the balcony of the in-laws, it HAD to fit 100% flat packed in the boot of my car (it fits with 5 mm to spare (witdh), no kidding.
I've relocated the solar vent/fan to the front where the sun would hit it more than when it was in the back. The wiring has been improved too.
I guess the only flaw in my design that I can think off is that I could have build it 5 cm longer (it's not quite a square, about 105cm/95cm)
