  1. of This is what I like to see - the DATE in the subject of the post. Annoys the hell out me, the number of meaningless 'clear tonight' or 'aurora alert' posts etc. there are with no date reference in the subject header!
  2. Heavy duty latch clamps? https://www.ebay.co.uk/sch/i.html?_odkw=heavy+duty+latch+clamps&_sop=7&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xheavy+duty+latch+clamps.TRS0&_nkw=heavy+duty+latch+clamps&_sacat=0
  3. Plans to grant the Clwydian Range in north east Wales "Dark Sky" status have moved a step closer. Members of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty Committee voted to submit an application for the status on Friday. The International Dark Sky Association makes the award to areas where the night sky is "outstanding" and light pollution is minimised. There are 11 dark sky reserves across the world. If granted, it would follow the Brecon Beacons and Snowdonia in having the designation. http://www.bbc.co.uk/news/uk-wales-north-east-wales-42924441 Looks positive to me.
  4. Never hit itself yet (one reason I advocate a narrow pier design and no 'leveling plate'.....). By far the bigger issue for me is cable managment- always a risk of something going wrong there!
  5. Install a pier- the only thing the scope can clash with now is my head....
  6. Could be to do with the impact velocity of the particles? Not all hit the at 60,000kmh, some probably are hoovered up by the Earth's gravity and just drift down because of thier small mass.
  7. Moon overload....... ......sort of sums up my day so far!
  8. Hit the nail on the head there. No computer needed, just a cheap intervalometer. Olly's point about corrected imaging circle size is valid though. Not many scopes out there can properly utilize the whole area of a large CCD. One of the main reasons I've never gone full frame.
  9. Must admit I use stainless - on the basis that we astronomers are nowhere need the max load stress, they don't rust, and we don't use anything other than stainless at work.....
  10. It's a bit more complicated than that- high grade carbon-steel bolts are stronger.
  11. Avex Interactive UK Light Pollution Map https://www.avex-asso.org/dossiers/pl/uk/index.html
  12. Near Llanbrynmair, but to be fair you could get equally dark skies a lot closer to Ellesmere Port than that.
  13. ....just over an hours drive from Ellesmere I don't bother imaging from the Midlands any more.
  14. I still can't figure out why that scope didn't work for you? The F4 makes a huge difference in data vs exposure times. A single 180s sub of M78 with my GSO 6" F4- in focus and picking up the faint stuff!
  15. I use both OAG and guide scopes. OAG on long focal lengths or long subs and guide scope for anything else. Simples.
  16. The extra data is starting to show there I think. Is this one of your fast F4 Newts or a slower tube?
  17. I had a look at some of my data for this object - I went as long as 20 minutes with my Canon 40D. Data seems to have won over the noise in this 1200s ISO1000 sub.
  18. How dark are your skies? It might be worth trying longer subs on this target.
  19. Great image - I love M78, doesn't get targeted often enough due to other 'easier' objects nearby. Any details on the instruments used?
  20. Well done on finding these faint fuzzies- it's a great thrill to find these things first time.
  21. As above- I usaully hang a builders bucket of bricks (or water) from under the centre of the tripod. The amount of stability and damping you get is amazing.
  22. 2" mounted - mainly as DSLR's have larger sensors.
