  1. I thought the image of Charon was impressive enough but the close up showing the mountains is something else. There is so much to discover just from these few images, absolutely amazing mission!
  2. Given the energy of some cosmic rays wouldn't they be created in the atmosphere? Detecting them is entirely another matter...
  3. Its going to take about a year I think for all the data to come back! Absolutely fascinating and very surprising that Pluto appears red. Can't wait to see the first images tomorrow.
  4. I've been to Cerro Tololo but it was some time ago (1998) and I did have telescope time so I can't really help you much there. I have however found this which may be useful. http://www.ctio.noao.edu/noao/content/Tololo-and-Tourism There are various sections about tourism in general and astro tourism so you might find something. As for non astronomy things, I found Chile to be a wonderful country so you should have no problems there, I seem to remember La Serena (a nearby town) was particularly nice. Good luck and enjoy!
  5. I see it going all the way up to 50 I wonder how much the 750mm one will cost.... Not that I could ever afford it!
  6. Apologies for resurrecting an old thread but I finally fixed the problem and thought it might be of interest in case anyone else experiences similar problems. After playing around with it for a while I noticed that as the red dot finder inclinded further from the horizontal it would suddenly switch itself off. Turned out the metal strip that holds the battery in place was a little loose causing it to be disconnected as it started to point upwards. A quick tweak and it is working fine
  7. That is a very good point you raise. Taking a look outside first thing in the morning as the sky is starting to get lighter more often than not shows several aircraft trails stretching across the entire sky. I doubt we notice them looking through an eyepiece at night but it must have some effect as you say.
  8. I just want to say thank you for such a fascinating thread. With regard to M45, when I was growing up I distinctly remember being able to count at least 10 on a good dark night but this was from a reasonably dark semi-rural location. The last really good night I remember was back in September 2013 before I got a telescope, on this occasion from a different reasonably dark semi-rural location M31 was visible as a rather clear and extended with the naked eye. I also own both the MV 24 and 16mm eyepieces. Although I can't offer anywhere near as much information as has already been discussed I can
  9. I've only seen 2 so far. Having said that, one of them was whilst looking through my telescope which I've never experienced before
  10. This is were the book "turn left at orion" comes in. It can see overwhelming at first when you don't know your way around the sky and what is out there to see. This book is nicely laid out for the various times of year and has a nice list of objects that is more than enough to get you started with detailed instructions on how to find them. I've got other books which are more glossy with nice pictures but as an observing guide turn left at orion really can't be beat. I'll also second the recommendation for the 150p dob to start with, I have the 130p heritage and it is a great scope. The 150p wi
  11. I too have this telescope and I also highly recommend it. Although the slop issue has been mentioned I find it is not too bad at all and most of the time I am not really aware of it. If it is a problem it is a cheap and simple fix. The 25mm eyepiece that comes with the scope is actually not bad at all. The 10mm is not great though so if you do want to get eyepieces something in the 5-8mm range and something to replace the 10mm are good options. I have a 5mm BST which works well and has given some really nice views of Jupiter and the moon. I also definitely second the MV recommendations, I have
  12. I spotted this and thought it might be of some interest... http://www.telegraph.co.uk/news/science/science-news/11288601/Have-scientists-found-first-sign-of-Dark-Matter.html Hardly conclusive I guess, but I did find it interesting how they used the observation to calculate what the signal from our galaxy would look like, which they subsequently observed.
  13. I saw that at FLO but out of stock, I do like the look of that actually thank you. These forums are amazing by the way Thanks everyone!
  14. That I didn't know, thank you! I did notice a Rigel QuikFinder Compact Reflex Sight at FLO, if that fits then it would be perfect. I'll also check astroboot thank you, although as indicated just above it may not be quite so urgent. Maybe something I could ask for a Christmas present
