  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.
