I and my girlfriend was out in the forest and looking for Sweden's ancient history. We found what we looked for, but also something totally different, three old observatories. That's the observatories that was mentioned in the text about Swedish old observatories, translated to english by me. We had already drawed plan to visit this observatory, Tamm's observatoru in the future. But didn't expect to find it here.
Some photos from this lucky day and information I have collected:
I'm addressing this problem with our Scopedome shutter since December 2020. The problem occurs every once in a while either during opening or closing the shutter especially approaching the full-close position wherein it creates a loud "bang" noise.
After inspecting the dome, I just found out that the gear is now not touching exactly the latch hole of the shutter. Herewith attached below are the images showing the problem.
Any tips/suggestions on how to resolve this issue, particularly on the aligning them, what to use etc., if needs replacement?
Excuse me if there are incorrect terms. I'm not that familiar with dome components.
Thank you very much. Clear skies.
Hey guys, hoping to launch my Observatory build this year (2.7m Pulsar), and looking for some advice on electrical requirements. Apologies for the brain dump, but when I started typing this up, I just seemed to keep coming up with other questions:-)
My observatory site will require a 20m cable run from the house, which I am hoping will be as a spur off existing circuitry, although still to get my tame electrician to give me the low-down on the best solution.
Normal approach is to run a sub-surface conduit for both data and electricity supply, however it occurred to me that an alternative approach might be to have above surface conduits running from a supply point at the house to a receiving point at the observatory, somewhat along the lines of caravan hookups at camping sites. Would be interested to hear from folks on this approach, especially if anyone has gone down this route.
Assuming we go down the sub-surface route:
1/. What would be an appropriate depth to lay the power and data conduits?
2/. Has anybody had data quality issues when running Ethernet in close proximity to a power conduit? Data medium will be over CAT6, so I’m hoping that the more stringent specifications will be sufficient to remove this as a possible problem. I’m aware of general protocols, which advise against laying data cables parallel to power cables for extended lengths. In the event that this is still an issue what approaches have people taken to providing similar data solutions for their own observatories?
3/. I’m also interested in future proofing the obsy with regards to power sockets. Straight up, the following supply requirements spring to mind:
— Dew control (transformed to 12V DC). Possible I may continue to use my existing batteries for this purpose. How have you guys tackled this?
So I’m thinking 4 double sockets should cater for these and provide me with sufficient expansion for unforeseen circumstance. Is this sufficient? Am I missing something?
What is the maximum advisable current draw? Intention is to have all supplies run through a fuse box local to the observatory and of course all plugs will utilise standard domestic fuses as well.
With regards to lighting what solutions have you guys gone with? I was thinking about just using a single standard red outdoor light, but it occurred to me that shadows might be an issue and so got to thinking about a surround lighting approach, perhaps using something similar to this:
On the possibility of an entirely WIFI based approach to data. Is this realistic? This would likely require booster units for the existing house WIFI, however I’m thinking that even then, data transfer rates for imaging might be an issue if I graduate to remote operation.
Hi, I have recently bought and mounted a third version of a weather monitoring station, this time a non DIY product - The Lunatico AAG Cloudwatcher and the Solo computer with it.
I have been running a weather monitor for five years now, but because i lack front-end coding (or hasn't taken the time learning it) I have been looking for a out-of-the-box product which presents the data in a nice way.
The difference between this product and the two other models I have made earlier is the raspberry pi and the webserver capability.
The earlier versions hade the capability to output a "safe" or "not safe" command to my sequence program.
This version from lunatico has the capability to output a folder in my network with a boltwood textfile, or direct via ASCOM.
So far, i have been running this for two weeks now and it is working very nice. The data is presented on a webpage very nice and it has 100% uptime as of now.
Just one time, the cloud temperature has been presented wrong, this happend during a weather change from +2 degrees celsius and overcast to about -10 degree celsius with clear sky in a matter in a couple of hours.
please feel free to comment and ask questions
As a beginner I'm in the process of acquiring all the equipment necessary to start imaging on an EQ3pro.
As we're all experiencing, it's tricky to get your hands on any equipment at the moment due to stock shortage so I've been thinking of ways to keep myself busy in the meantime!
I thought I'd share a project I worked on today that will give me a greater view of the night sky from my covered balcony.
There are some good views from the balcony from East to West but using the tripod severely limits any overhead views.
To bring the setup closer to the edge of the balcony I've built a shelf attached to the sturdy (wall set) balcony itself with a wooden pier for support. The pier itself sits on the balcony floorboards support beam and so there is no noticeable wobble.
I've included an image of the spirit level to show my effort in keeping the mount level.
The mount neatly slides off the feet of the shelf which I'm hoping will reduce setup time (once I have the opportunity to polar align!) The north foot points to magnetic north.
Whilst building I realised I could have saved myself some trouble by using a metal telescopic "chin-up bar", not least from the missis who wasn't too happy I drilled into the decking!
I'm quite happy with the outcome and glad I could get into a hardware store before "tier 4" sets in.
