  1. Greg even though I have sealed the motherboard and cards with circuit board lacquer, I am still thinking about doing something. Most of the year it is quite dry. Only three months a year I need to worry about. I found an easy to use thermostat that outputs twelve volts once a temperature (I set) is reach. This thermostat can also come with a moisture detector to detect dew. So I was thinking of using something like a simple dew heater or nichrome wire that kicks in once conditions near the PC become dangerous. It would be a pretty simple project and the PC I recently had built is 6 core and is the fastest thing I've ever seen, so I really want to look after it. I think this project would be worth the small amount of time and money. I'll checkout the dehumidifier option, could be even easier. Ray
  2. I found a product called circuit board lacquer. Also called circuit board varnish or clear coat. Dries super fast, does not conduct electricity. For anyone considering this, make sure not to spray it inside any open plugs for obvious reasons. Keep away from fans as well. Moisture proof your observatory electronics people. Ray
  3. Just got my observatory PC out of the computer repair shop again, new motherboard, new processor, power supply, tower, etc. Computer guy showed me traces of moisture that had wreaked havoc on my previous PC for years. How do others here keep there computers, laptops, PC or other configs immune from dew / moisture / frost / dampness / etc. It is easy to ensure things don't get moist damaged when you are using them, but for PC's inside observatories permanently, there are challenges. I am thinking something like a dew heater on a thermostat that kicks in once it gets to eight degrees or similar could word. Desiccant would not really work because of the air flow that must happen for a PC tower pulling air in from outside the tower. Otherwise spraying the motherboard (front and back) with a lacquer to waterproof it could also work (but this could interfere with plugs etc). The challenge is certainly not beyond me, but I imagine others in colder climates must have already pioneered various paths. Please share. Regards Ray
  4. Beauty

    Beautiful colours on it either way. Ray
  5. New filter

    I think you will love NB mate. Its quite a craft. Over the last new moon, I managed to get a few hours on The Swan in Ha. Bad weather since, but the first clear night I get I'll get the SII and OIII data. However the monochrome Ha data is great to look already. I really enjoy NB. Ray

    Great timing mate. Ray
  7. Yesterday's EPOD

    Well done Prof. Ray
  8. White one

    Wow Prof, that is quite incredible. Ray
  9. They are over engineering their software. Programmers needs to justify their jobs I guess, and by creating new features all the time gives them the work they need. I recently had to fill out my address on a website contact form, and as you start to type, the AI on the site tries to predict your address (anywhere in the world) and inputs your address incorrectly and prevents me from writing it in. Great example of over-engineering and programmers coming up with software that is not necessary and just makes things more annoying to use. Could give you ten other examples. Frustrating, ahh! Ray
  10. Pearl Cluster

    Beautiful work mate. Ray
  11. M51 from last night

    How are things in Pasadena Tony? Hope you are well mate. Ray
  12. Yes, really takes the joy out of it. Work perfectly now though. So all good. Ray
  13. lol, I know, I'm just looking for the easy way out, but its time to clean them anyway. I have had a long hiatus from AP (work, study, family, broken observatory computer). So I am looking forward to getting some photos right after this full moon goes away. I am thinking Sombrero is well positioned at the moment. Ray
  14. After reinstalling a new hard drive with software, Maxim has forgotten the position of my eight filters. RGB, LUM and narrowband. The filters are mounted as well; not with a steel rim with their name on (just round glass). They were originally installed at QSI before shipping. The software automatically knew what was where. However I can't get the software to recognize them anymore. Rather than open the camera up to access the filter wheel, is there a sneaky way to ascertain which filter is what by looking at a star or nebula? I am using a monochrome camera. Cheers Ray
  15. Hi Dave, Thanks for the offer to borrow a camera. I would only be using a camera like this for star trails, wide-field (piggybacking) and lightning shots (and meteor showers). I can't see myself connecting it to a telescope (have a dedicated CCD for that), but who knows, maybe one day I might. I love the chip size on the 750D. I'm down at Curtin a lot, so maybe I'll swing past when the isolation tapers off. Otherwise you can pop up this way and checkout my observatory (whichever works for you mate). Ray
