  1. A good point. Unless you have a properly set up focuser a laser may not give very acurate results. Also if the focuser drawtube shifts as it moves more problems.
  2. Had two Hotech lasers and both were perfectly colimated out of the box Tried a few others but none were close to being colimated.. Lasers though do require a decent focuser to work properly. For secondary collimatiion nothing beats a Concentre for accuracy but they are a bit pricy..
  3. The decimal comma vs the decimal point. https://uk.smartickmethod.com/blog/math/learning-resources/decimal-separators/
  4. Forecast is poor for the transit here.
  5. There is the OO carbon fibre tube option if you are concerned about stiffness.
  6. You would think you would be safe in a peaceful Swiss alpine meadow. https://www.thelocal.ch/20120725/cows-attack-woman-hiking-in-alpine-meadow
  7. I see why they’re only producing 300 and not making it a regular production item. Selling more than that could be a problem at that price. Wonder if this bit of price gouging will hurt their reputation?
  8. Looks a lot like my doormat when turned upside down.
  9. I just use a photo editor to blur the address details.
  10. Why not check on the Telescope Express website.? They have plenty of R&P focusers available and sell the adapters as well. BTW Telescope House is owned by Bresser.in Germany and ships everything from Germany. https://www.teleskop-express.de/shop/index.php/cat/c92_Focusers.html
  11. Never mind the “Rules” but common curtesy is to reply reasonably promptly to an ad enquiry or if you will be away and unable to reply until a certain date mention it in your ad.
  12. Usually it’s just a mention that a PM has been sent sometimes with the comment I’ll take that please or something similar.
  13. At that price Televue can insert the eyepiece in another place rather than a scope.
  14. Wonder how much people will be asking for one on eBay etc. when they are all sold out 2,000.00 perhaps.
  15. Funny the way things work out sometimes.
  16. Judging by the thickness could be an older mirror and possibly recoated. At €40 looks to be a good buy.
  17. You might need one of these if your problem is lack of infocus travel. https://www.firstlightoptics.com/zwo-accessories/zwo-low-profile-replacement-camera-cover-for-all-uncooled-zwo-cameras.html
  18. Apparently dogs are a common factor when cows attack. https://www.countryfile.com/go-outdoors/walks/how-dangerous-are-cows-to-walkers/
  19. Cows can be quite dangeous. Seems to be a story every few weeks about someone being trampled to death by a herd of cows. A few years ago saw a cow jump,clear over a high farm gate. Didn’t know cows could jump like that. Should enter that one in the Puissance at the Olympia horse show.
  20. When this happens to me I send them a friendly reminder in case they didn’t get the first message. Find it’s best to post that you have sent a PM on the sale thread as well as sending a PM. If no reply then I probably wouldn't bother replying to any other thing they put up for sale later on.
  21. FLO sent me a a couple a while ago so worth asking them.
