  1. Anyone seen these available in the UK yet? http://astrosolar.com/en/information/news-en/baader-solar-filter/
  2. Why do you want such a structure - what is it for, what will it achieve?
  3. Argh, typo - fat fingers on iPad. I hope you spotted it. (not 268). The computer and the APC need to be on the same network. If the subnet is set to (usual for this type of setup), the first three numbers need to be the same on both computer and APC, but the fourth number needs to be different. You then put into the address bar at the top of IE/Chrome/Safari to get the Apc login screen.
  4. You could just (temporarily) tell a computer to use IP address subnet and use that computer to log onto the Apc to change its settings. No new cables needed.
  5. If you still can't get the Apc working, I'd be happy to give it a go if you send it here.
  6. The garage is 8 feet high - how far away from the garage will the pier be situated? I find that there's little point imaging below 20 degrees above the horizon. You can use that to work out how high your scope needs to be mounted, then using the height of your mount, how high your pier needs to be. Quite probably much shorter than 8 feet.
  7. Well, in the end I set at LOW and 60% humidity and ran it all year as advised by the company that sells them (and gives the discount) - and all was working fine until a few weeks ago. I've asked them for any advice but I suspect they will be having a well earned break, so I thought I would also ask on here. Recently the dehumidifier has stopped and the "water full" light has indicated. Looking at it, the water tank has indeed been full and I have had to empty it. This is a surprise as I have a hole drilled through my observatory wall and the supplied pipe attached to the nozzle. The pipe has a decent fall*, has been working all year and there has been no freezing weather down here - not even a frost! Most of the time it has been above 7 degrees, so my winter tyres have been entirely wasted. I had no similar problems last year in January/February when the weather was much colder. There are no kinks to the pipe and no obstructions. The machine is just under a year old. Is this a fault or am I missing some simple instruction that will make it work correctly? * and I have increased it further by standing the dehumidifier on a plank of wood.
  8. I get great results with Elbrus, but I agree the settings are paramount. Works 9 times out of 10, and when it fails over to astrometry.net, that takes care of the 1 in 10. Focussing, once I set it to take 8 second exposures, works fine too.
  9. Good on FLO sorting it so quickly for you. My question: Why buy the GT81 when you have an Esprit 80? Aren't you happy with the Esprit? I ask as someone who was considering one (and the GT81).
  10. Connect up your neq6 to a computer and use it to assist your polar alignment using something like AstroTortilla that doesn't need you to use specific stars.
  11. I use mastercrete at whatever mix it says on the bag. About 1:4 cement:all-in-ballast I think. I'm sure you could get away with less cement, but it's less than a fiver a bag and you only do it once.
  12. If you get 0-0-0-0 it hasn't got an IP address. To log on to it with website, first you need an IP address. Then just put that address in a web browser. Username and password are both apc. Out of the factory, it is set up to take an address from a dhcp or bootp server. (I'd disable the requirement of vendor specific cookie at the first opportunity) http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=ap7921&tab=documentation See manual, page 10 Best bet is use the wizard, page 9, download here; http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=ap7921&tab=software Otherwise, use the telnet options (ping seems easiest way). As long as the password is the default. Otherwise, you will need the special serial cable (on ebay)
  13. Power switch doesn't need a driver - it's driven from a web interface. Default username and password is apc. Manual is online. Press and hold button to find it's IP address. Hopefully set up already with a static address or DHCP without the magic cookie. Otherwise you need a cable.
  14. Glad you're up and running. Beware the ACP power switch has an unusual way of using DHCP if you set that option. What's the second solar panel for?
  15. Looks like you've closed off the top at the back - where does the rainwater drain out?
