  1. I may have misunderstood your problem but ..... I use ADM Dovetail Counterweight Mike
  2. I'm going in the opposite direction. There was a chicken coop and run where I'm getting ready to build my obsy. We have a fancy septic tank which discharges into a stream at the far end of the garden - sadly, I have no idea where the pipes run but I'm willing to bet money I will find one when I start digging.
  3. Looks very interesting. Always good to see new designs. Mike
  4. Love the video. Brilliant. Mike
  5. That is the neatest hole and reinforcing I've ever seen. I'm really looking forward to seeing the rest of the build. You are setting a high standard. Mike PS Is it my imagination of can I hear the strains of "Waltzing Matilda"?
  6. Good progress Ray, you are really off and running now. Just a couple of questions. Please don't take them as criticism, they are intended as an honest attempt to help. Won't you need more supports for the rim joists as well as the floor joists ie more MOT and blocks? Will you be able to access the sides of the observatory and fence for maintenance - the base looks very close to the two fences? Mike
  7. I'm sure you are right - in many respects you will be committed at that point. Good luck. I'm at the "can't make my mind up stage" which on the one hand is frustrating because I want to get on with it but on the other hand, it ensures I give it plenty of thought. I have to finish off all the jobs that SWMBO has prioritised, otherwise I might end up living in it. Mike
  8. Good stuff Ray. I'll be watching with interest since I hope to start on my observatory early in the new year. Mike PS Whereabouts in Kent are you? I'm on the Kent / E. Sussex border.
  9. I'll bring issues 12 to 133 of Sky At Night magazine (not including the CDs) if anyone wants them. They are just taking up space (no pun) and I never look at them. Free to a good home. PM me if you are interested, Mike
  10. I found the following in SkyMap Pro. I have no idea if it is correct or not. Probably doesn't add anything to what you have already found. Mike Information about PGC 1467 Basic object information Object name: PGC 1467 Object type: Galaxy Magnitude: 11.5 Position information Apparent RA: 0h 23m 47s Apparent Dec: +25° 35' 54" Constellation: Andromeda Altitude: 10° 49' 52" Azimuth: 297° 44' 31" Hour angle: 7h 1m 32s Rise: 14h 34m 18s Transit: 23h 3m 57s Set: 7h 37m 33s Names and designations PGC 1467 3ZW 6 Star atlas chart numbers Herald-Bobroff Astroatlas: Chart C-21 Millennium Star Atlas: Charts 173-174 (Vol I) Sky Atlas 2000.0: Chart 4 Uranometria 2000: Chart 126, Vol 1 PGC 1999 Supplied by the LEDA team at the CRAL-Observatoire de Lyon (France) Names and designations PGC 1467 3ZW 6 Position information RA (J2000.0): 00h 22m 53.3s (High accuracy) Dec (J2000.0): +25° 30' 14" Galactic longitude: 114.87° Galactic latitude: -36.92° Supergalactic longitude: 319.50° Supergalactic latitude: 13.77° Size and shape information Morphological information Magnitude and colour index information Total B magnitude: 11.500 Error in B magnitude: 1.000 Error in log10 velocity dispersion: 52.428 Galactic extinction in B mag: 0.292 mag Extinction in B mag due to inclination: 0.000 mag Total apparent corrected B mag: 11.208
  11. My goodness, you work hard. This is going to be a great build to follow. Mike
  12. That's what I was going to suggest. As an alternative to wifi you could consider power line adapters. Mike
  13. There is a big difference between bragging and just being proud of what you have built. I'm positive you are in the latter camp. I'm enjoying your build and I'm very impressed with your attention to detail. Good luck with the weather and your roof design. Mike
  14. Not sure I'd be able to help but ... your link doesn't work for me. Mike
  15. I have a "vibration alarm" on my shed (storage shed not an obsy). It is intended to detect any forceful break ins. http://www.crimepreventionproducts.co.uk/home-security/door-window-alarms/battery-operated-vibration-door-alarm
  16. Very simple. Very elegant. I like it. Mike
  17. They aren't too far from where my parents live so I'll pop in when I'm next up there. Looks like good quality kit. Mike
  18. I'm curious too. If I can sell my house, I'll be buying a new one with two south facing velux windows in one of the top floor bedrooms. It would be terrific if I could find a way have the window open such that it leaves an unobscured view. Mike
  19. I've not built an obsy but I have built a couple of sheds with feather-edge cladding. The boards have a tendency to cup so I found it better to nail through the lower thicker part which also goes through the thinner part of the board below. That way each board is held top and bottom on each stud, reducing the tendency to cup. I wasn't concerned about the visibility of the nails but keeping them "lined up" makes the job look neater. Mike
  20. Hi Ole, They sell an Alpha Column Medium and an Alpha Column Large. The larger one having a larger cross-section. I got a couple of prices for the medium one just to get an idea of cost and the quoted prices included carriage, VAT and the cost of a controller and a handset - basically everything you need. The price depends on the amount of travel (stroke) so the quotes I got were for 500mm stroke - £710 and for 900mm stroke - £1,254. Mike
  21. Has anyone used one of these as a pier - they look quite similar to Pier-Tech piers? I'd like to know how stable they are. Their very helpful staff assure me that at least one person bought one for that purpose but they were unable to find any contact details for them.
