  1. You may be aware of this but here is the link if you need it https://myscienceshop.com/catalog/downloads where you could buy pdf downloads of those magazines from Kalmbach . I have bought a few of these pdf s at times when the contents were of specific interest. Hope this is a help in your quest. Deep Sky magazine was availlable from the same route and source.?
  2. This paper may be of interest re use of multiple optical fibres for astro work.. http://adsabs.harvard.edu/full/1998ASPC..152....3P .Hope this helps
  3. I believe that what you have is a Carey Mask http://www.geoastro.co.uk/careymask.htm . Should work on the basis of the comments in the link including the comments on the diffraction spikes you get with that mask pattern. Hope this info helps.
  4. The material that was carried by Wilko is Black deco velour by d-c-fix in Germany . It is identified by the German company as 348-0005. Checking just now I find a few suppliers for the specific item on Amazon UK but nothing on Ebay. Hope this is a help. Nothing wrong in holding a stock when you find it of a couple of rolls (as it does not need feeding or watering)
  5. Please could you provide information on the 3D printer you purchased on Ebay . Technical specification listed by Manuf/Supplier etc . Trying to resist the urge to splurge but worth a punt at that price. Hoping you can help. Ta
  6. Have a look here re tapping copper https://www.model-engineer.co.uk/forums/postings.asp?th=95556 . Copper work hardens. Some lubricant may help. A manual job (with the hands) -no power - A lathe could be used (unpowered) keeping all square that way with a die holder head and hand rotating the chuck. Two steps forward and one back was drummed gently in to me when tapping threads back at school more than 60 years ago
  7. Here is my very first single shot with the Panasonic Lumix FZ72 camera (slightly out of focus) as a straight download with no processing at all. Camera at 60X optical zoom on a fixed tripod.
  8. The Panasonic Lumix FZ 72 has a 60X optical zoom so can take pics of the moon without the use of a telescope (at all) with great views of the craters and mare . Have a visit here http://bridgecameraastroimaging.blogspot.com/ and see what the camera can do with just a tripod and no drive. The blogger is Dr Steve Wainwright who originated the QCUIAG (web cam imaging etc).
  9. There is a regular Newsletter available on the net here http://www.jodrellbank.manchester.ac.uk/news-and-events/jbca-newsletter/august-2017/ . There are three different recent issues there. Tim O'Brien (Assistant Director) is active on Twitter . Worth having a look here http://www.jodrellbank.manchester.ac.uk/people/staff-spotlights/tim-o-brien/ . As far as I am aware it is still operational and one of the Newsletters flags plans for further upgrades to the dish.
  10. Hi, Try using snailmail via the information in this PDF https://britastro.org/sites/default/files/Booking Form - BAA-AAVSO Warwick.pdf Hope this helps.
  11. You may find this comet site helpful http://www.cometwatch.co.uk/bright-comets-of-2018/ . I do not expect it to be a Hale Bopp or Hyakutaki but am hoping for a naked eye comet. It should be at it's brightest in the tail end of the year so under darker skies (but clouds abound ) . There is good information available here http://www.ast.cam.ac.uk/~jds/ . Keep looking up
  12. Are there any details of a 2018 event at a similar (or close venue ) please so I can add it to my calendar.Thanks
  13. Please can you identify the aliphatic/s you used and the chemical 'quality' ? Analar ? Thanks
  14. A grand lad and a guy who got a lot out of astronomy science with a pair of binoculars.Very proud of his Yorkshire roots and a member of the county cricket club. A great friend over some 43 years . RIP Melvyn.
  15. Have a look here http://www.skynews.ca/resources/astronomy-clubs/ and search out Ontario in the listings. You know your geography there better than I so you should find something that is not too far away. The Sky News magazine is great and I subscribe from the UK. I had family connections over there (originally in Saskatchewan but later in British Columbia and London,Ontario) but my generation have lost contact. I hope this helps.
  16. Same problem here in West Yorkshire . 'Site cannot be reached'. It was working OK an hour ago( ca 2200 hrs BST)
  17. The Deep Sky Section of the BAA handles Double Stars through John McCue . He can be contacted via the DS Section Director. Bob Argyle's book on Observing and Measuring Visual Double Stars (Springer PM Series 2nd Edn) may well have pointers too. Hope this helps
  18. In reply to disciplus55 (Silvain) there is a thread running here https://www.astromart.com/forums/viewpost.asp?forum_post_id=342745 that may provide a bit more Clave history info. I was asked to advise non astro relatives on various pieces on astro kit value for a deceased's estate. There were several Claves plus two Apos (Takahashi & Vixen) and three different sets of image stabilised bins. Hope this helps.
  19. Oz sees ABC showing Stargazing Live in early April here http://www.abc.net.au/tv/programs/stargazing-live/ with Brian Cox . Not quite the same show and with 1/2 hr discussions too. Picked the info up on Ice in Space. Sadly I have not found a way of viewing it in in the UK over the net. Rumour has it that some UK resident Aussies have access to their homeland TV over the net here as a paid for service. Perhaps a view could be obtained for a friendly supper and a few tinnies ?
  20. As suggested these are satellite trails from geostationary satellites. A Google search with geostationary ,astrophotography and Orion as search parameters will give you info , piccies and compiled video
  21. Have a look at Tim Haymes website http://www.stargazer.me.uk/asteroids/asteroids.htm .Use the menu on the LH of the screen to view the tools that can be used for occultation work. Follow through the BAA website to the Asteroid and Remote section and eventually you will find an occultation link on the external website. The UK hosts an international meeting occultation meeting http://www.esop35.uk/ in Guilford this August. It should be possible to attend as a day registrant. Here is a sample of the international JOA http://www.occultations.org/on/JOA/Vol01/JOAvol1num1.pdf Hop
  22. Hi kegstar , Try this source for starters http://www.starrynighteducation.com/resources_pronunciation.html .This is not definitive but a start ! There is a long running thread on here https://stargazerslounge.com/topic/15107-pronunciations-of-astronomy-terms/ too.Hope this helps.
  23. Currently amateur meteor spectroscopy is moving in to the video realm allowing dynamic recording of the emission profile of the flight. Cameras such as the Watec 902H series are used. A look here http://www.popastro.com/meteor/observingmeteors/spectra/index.php gives you an idea of what is going on recently. Bill Ward is the leading UK observer. . He posts occasional video on YouTube . Robin Leadbeater has a meteor video capture on his Three Hills website taken through a Jeulin grating with a modded 1004Ex video camera. That grating lead back to Paton Hawksley and the SA100 !
  24. Just a short note to flag up Sky at Night on the box next Wednesday http://www.bbc.co.uk/programmes/b06t3wst on the Christmas Star . Best wishes to you all down the valley in Wakey.
  25. A grand day out in Yorkshire in Leeds on Saturday 7 th November .Noted its not been flagged yet . I'm looking forward to the four talks and seeing folk I bump into once a year. Here is the link to details http://www.astronomyleeds.org.uk/Astromeet.html . Sadly domestic demands meant that I missed last years for the first time in a decade Hope to see some SGLers there.
