  1. Guys all excellent tips. Will crack on and post results, thanks for solid adevice all round
  2. I need help! I'm going to bend my threads! So I'm happy with the concrete and ballast mix ratio, but I'm looking at how much I need and with the block measuring at 60cm X 60cm X 60cm I've used an online calculator stating I need roughly 375kg ballast to 3 bags of 25kg cement but nowhere sells ballast in weight! I've looked at bulk bags hoping they would be enough but the reviews at B&Q/Wickes on their ballast are poor saying they're full of waste and rubbish. The smaller bags of ballast have no weight on them as it changes dramatically when we're and I have no idea where to get it from or how much I need. Any suggestions please.
  3. Thanks John, will definitely use this now I'm using concrete
  4. Well thanks guys, always worth jumping on and asking! I have found that when I've used postcrete for posts it needs a good mix (contrary to what the bag says!) to ensure there are no little pockets of powder but other than that I thought it would be strong enough contrary to what the guidance says that Johninderby kindly posted. The consideration i'd missed was the cost, having never mixed concrete before (assumed I have to use a mixer !) I thought it would be like for like in price but clearly not. Another question then if I may... What is the advantage of setting the concrete and then drilling holes for the threads? The only method I've seen until now was sinking the threads in the wet concrete using a template? Should I use rebar or will the fibres above be sufficient? thoughts again please....
  5. Hi guys, Just a quickie, I've moved and am relocating my steel pier. So, would postcrete do a decent job for the footing of my steel pier in conjunction with rebar and 14mm threaded bolts? I'd make the hole big enough to cater for the size of the pier base and threads, I'm just purely asking if it will be strong enough as it is designed to hold concrete fence posts up with fence panels in the wind. The alternative is to mix concrete but if postcrete in the right quantity will do the job satisfactorily I'd choose that for convenience. Thoughts please Adaaam75
  6. As I understand it they make aligning and reasonably accurate tracking much easier to achieve hence the cost and demand i guess. I'm in agreement with you BF79 as I'm obviously doing something wrong and do tend to just "aim" at easy to find objects for now, but will not be one of those guys that gives up, I know I'm inputting data in wrong or not polar aligning properly however I'm moving soon and with my new polarscope and pier to be installed I'm hoping once I actually get it right I won't need a Starsense, but never say never, running the cost of one past the missus is a challenge in its own right so if I can avoid the need I will.....
  7. Hi guys, Having had difficulty in aligning and never actually managing to get my AVX to track to the standard I know it can, is the Celestron StarSense gadget the answer? I know I can align my scope accurately if I put the effort in and having moved last year I’ve been unable to have my mount fixed on a pier so I’m seriously considering this piece of kit as an easier way to align and to motivate me to get out more often. Please share your thoughts..... Adaaam75
  8. Here is my plan b in build phase guys. Almost there! Pier courtesy of a very kind brother in law minus cost of materials!
  9. Ooooh update! Who'd have thought I'd be lucky enough to have a brother in law who can weld! £200 all in. Cost of steel and powder coating. Just need the time to install it now and I'm set.
  10. All I have t do now is wait for my pier to be delivered to complete the obs, I will then paint and sort the floor out! Watch this space....
  11. I then cracked on with the rolling roof rebuilding the roof from scratch. The hardest part was aligning the wheels in the runners, I'm not a mechanical engineer! The roof weighs approx 100 kgs but is designed to not bow and only took two of us to lift t up. The wheels are nylon castors that roll along on metal troughs the entire length of the runners, with a slight decline to allow water to roll out the ends when it rains. The back of the roof has marine material that drops down to protect the gap and simply flaps up over the top when I roll the roof off.
  12. Hi guys, I thought it was about time I posted the progress of my shed conversion observatory. I've decided to post my observatory project from the start to where I am now including the failed flip lid design and it has been an unsurprisingly long road with what feels like some wasted spends on the flip top design but I am almost there. I was lucky enough to have two good sized sheds in our garden and as we only needed one my wife had already conceded the second as my future observatory. The foundations are good as is the quality of the build with thick solid T&G panels and handy double doors. I am also blessed with a 360 degree view of the night sky with only the first 5 degrees of the horizon blocked by my bungalow and a few trees in the distance. The flip top design would work as demonstrated by other members had I chosen to use a material other than wood for the roof (or rebuilt the roof with a lighter wood construction) however I wanted to maintain the natural look in my garden and chose wood with felt. The overall design was great, water tight and mechanically sound however to lift each half of the roof took some effort due to the weight (50-60kgs) and when it swung past the 90 degree angle the chains were under too much stress to “catch it” going the other way. The same principle applied when I was closing it again. There were work arounds but I decided to go back to the drawing board and chose the popular rolling roof design. Here are the flip lid shots I took including the 8 firedoor hinges used and the water tight overlap for the roof split.
  13. Was able to get out the following night though. Hoping to get a clear night as in to capture the waxing crescent before it's a full moon again!
  14. What clear skies??? A week of planning for my first observing night in 2 weeks and reported cloudless cold night skies all night only to be ruined by a surprise blanket of white!!! I'm hitting Netflix for a couple of hours but I'm not hopeful. #typical
  15. Granted and if love to have the spare cash to get a semi decent entry CCD however i already have everything i need to try in my 550D and if i can zcheive similar imaged to PeterCPC above I'll be stoked!
