  1. Oh, yes - they are ideal Carole - I must admit I'd never heard of half of those myself!
  2. Thanks Carole, as you note it I shall probably be spoilt for choice when I get around to looking through the webpages offered above, but thanks for responding. I love the way that a lot of the 'common' names for these things are because of what they resemble, like catseye, dumbell, ring, horsehead that's why I think they will make fun as well as informative subjects for a quiz.
  3. That is quite superb - I must have missed it previously, well done. I bet you were pleased with the final result.
  4. What a train of disasters! I like the idea of the light on the outside of the building and think theidea of the use of the lamps that are used on tailboards could be really useful as they are surely waterproof!
  5. Many thanks for the offer - I've got a busy day today, but I'll have look when I get a few minutes and get back to you once I've found some to use.
  6. Hi There, that's great - many thanks. Sorry I didn't realise that anyone had posted - I'm used to getting notifications instantly when starting a new thread - now I see that I have to switch on 'follow topic' which I hadn't done. Good job I checked back anyway Yes, those are the sorts of things I had in mind. Also, those things with funny 'everyday' names, like the triangulum galaxy above (I love that it's not a triangle!) and as noted above those nebulas with everyday names like dumb-bell, horsehead and catseye - yes and the crab as noted above etc. Anything along those lines would be
  7. Just make sure that Daylight savings time adjustments don't mess up any timers LOL!
  8. If you haven't already done so I'd commend at the very least looking at the pictures on the first page of this thread: Then remember you have a far smaller scope that the 8" that is often used for comparison. FWIW you might benefit from looking out for a second hand Skywatcher 150P or 200P Dobsonian telescope which are often recommended for beginners.
  9. As many of you will be aware I am a STEM ambassador. Due to lockdown the STEM Ambassador group are making online quizzes about all sorts of science based things (doesn't have to be national curriculum). The quizzes are being done via a Powerpoint platform and typically take the form of a question, 3 options for answers, then the answer given and perhaps a brief factoid about the answer. There are generally about 10 questions per quizz. The thing is any images used really need to be sans copyright or with permission for them to use them (I think they OK with citing sources on the slides
  10. Oh, look....... I woke up this morning and had remembered that my parents sundial has an 'equation of time' printed on it to adjust the shadow position by a certain number of minutes at different times of year and that this was an uneven wave of changing magnitude. I wondered if this was due to the Analemma effect and it was - the shape is drawn on the graphs here: https://en.wikipedia.org/wiki/Equation_of_time#:~:text=The United States Naval Observatory,sun the sign is negative. I just thought this might be of additional interest.
  11. This is today's thing learned. I had no idea it made that sort of shape. In fact if it was April 1st I'd surely be wondering, but as it isn't it must be today's thing learned!
  12. Same story as above, I didn't have any problems with my non-branded Canon replacement batteries that I bought many years ago, when I need them too they still take a charge even now. Mind you I still try to use the Canon ones of which I have enough when I can dig them out.
  13. Many thanks, yes - I'd already found them, but it's nowhere near as convenient as having the obvious buttons on the bottom of the post.
