  1. North or Mid Wales- no too far from Brum. Llyn Peninsula is worth a look too. Brecon.....bit near the LP sources in the South
  2. Great project- wish I had access to a digger for my build. The gradient was too much to be safe though, I fear.
  3. The 30 degree slope at the bottom right is the horizon- the rest is trees. With the horizon leveled it would look more like this...
  4. Milky Way- Sagitarius through to Cepheus (105 degrees of sky!), Powys 3:00am this morning. Stack of seven, 300 second exposures.
  5. If you can find a site with not much 'human activtity' on the southern horizon, the views can be very good. Sagitarius on the horizon from the same spot with the moon out of the way (80mm lens)
  6. Looking good so far. If you stretch the budget to use armoured mains cable- then the metal shielding will surpress any RFI coming out of it. https://uk.rs-online.com/web/p/products/0379126/?grossPrice=Y&cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Cables_And_Wires-_-Electrical_Power_And_Industrial_Cable|Sy_Cable-_-PRODUCT_GROUP&matchtype=&pla-394215423796&s_kwcid=AL!7457!3!243856868087!!!g!394215423796!&gclid=EAIaIQobChMImZvJmJzu4QIV1ITVCh2bPwzwEAQYAyABEgLrXvD_BwE&gclsrc=aw.ds It would be better for burying and more resistant to rodent attack too (a big problem for me).
  7. Thanks- the star colours were enhanced in Photoshop using Noels Actions. The photo was taken at my observatory site in Mid Wales.
  8. The Council put a rather ineffective shade on it already. Fortunately this is not my main observing site.
  9. 1 1/2 hours worth of 30 second shots, combined in Startrails software. Fuji S5 Pro DSLR with Sigma 10-20mm zoom lens. From dark sky site in Mid Wales (full moon rising away to the left).
  10. I should suround it with solar panels......
  11. The brightness of LED lighting is overkill. Some luminaires are designed to be non-directional too. We used to have a softly glowing sodium lamp in the alleyway beside the house. And now.......
  12. York city centre, Stoke On Trent, North Shields- to name but a few, are also good observing sites.......
  13. ....and a bit baffling! The first three 'Truely Dark Sky Sites' I checked were in towns........ Clearly the 'data' is not being checked.
  14. If you can bring youself to re-check the collimation once after a couple of hours cooling down during the night- then you'll save yourself 600 Euro's............
  15. I've looked at buying this lens as a possible replacement for my ageing Nikon ED180 F2.8 which was the recomended fast widefield AP lens in its day. I don't want to hook it up to a CCD- so has anyone got any unprocessed, full frame DSLR images at F2 to post? I'd like to see if it is an improvement on the 'slow' old Nikon! And also how well it handles CA- one of the Nikons failings (on my lens at least) was issues with CA wide open. I found I had to stop down to F4 and use a Lumicom Minus Violet filter (almost half the cost I paid for the lens!!).
  16. Lets hope your neighbours don't a mind your scope peering over their houses!
  17. I got round the need for having lower side walls by parking the scope in the 'upside down' position- I think I'm unique in doing this!
  18. I supect granite will be a bit tougher. Amazing to think the Ancients made these huge granite obeliske with just copper & bronze tools...... https://en.wikipedia.org/wiki/Unfinished_obelisk
  19. All the resulting rubble found a use as backfill for the retaining wall on the downward side of the slope.
  20. You have my full sympathy. I hit bedrock within inches of the soil surface- but I still had several feet to go down, along a 12m long stretch of slope. It took months to get through! Fortunately my biggest rock was only wheelbarrow size- at least I know the pier is concreted to the bedrock!!
  21. I used plastic coated, galvanised steel cladding on my obsy build- dark green to blend into the landscape. It seems to have weathered the storms okay and to be honest looks as good now as the day we put it up- no rust or detoioration to the finish. I'm in the process of planning another shed with same material. Timber frame Dark green, sheet metal walls fitted to frame. Finshed off the two visible sides in waney edge pine cladding.
  22. In short- go for the biggest size 'shed' you're allowed. The 300PDS is a monster scope and once on a pier the eyepiece/camera could be as much as 9 feet off the ground when pointing up! So you'll need good access room all around for at least a seven step stepladder. I opted for 3m x 3m because the metal cladding wall material comes in 1m wide sheets. Here's what an F4 12" scope (i.e. shorter than yours) looks like in 3m x 3m obsy- I deliberately went big so I could store garden furniture/BBQ's etc in there as well.
