  1. Yeah, I agree with this theory. It all makes sense. You could think of it as a star (Black hole) forming from clouds of gas (the universe), and then running out of hydrogen (matter) and then going supernova (big bang) and then forming a supernova remnant (new universe).
  2. I was trying to search for it all day with my bins with the sun up, but with no luck. I actually thought it was closer to the sun until I saw it after sunset. Maybe thats why I couldnt find it.
  3. Yeh, I was thinking that even using binoculars on a ship must be hard. I cant be possible to use a tripod can it. and doing a sketch while hand holding binoculars must be even harder, having to keep finding the object over and over again. I suppose it is quite an easy star hop. What do you think the limiting naked eye magnitude was? Could you see any galaxies with the naked eye? I bet the milky way was fantastic.
  4. Thats better than ive got with my scope. I bet the skies are incredably dark out at sea? Were you working on an oil rig?
  5. Out of my Window (cant really see Saturn from anywhere else) I have been able to see Titan, Rhea, Dione, Iapetus. (Tethys is too close to Saturn and too dim to make out for me. It gets drowned out by the glare of Saturn. The reason I can see the much dimmer Iapetus is because it is far from Saturn, so no glare)
  6. I have the heritage. It’s great. I don’t think the focuser is a problem, it just needs to be oiled and then it will work beautifully and be very smooth. The oil compensates for the slack as well. I think that flocking is only essential if the scope is in the direct line of light of a street light or bright kitchen light. It is also amazingly quick to set up. Yesterday, I was looking for the dumbbell nebular for the first time. I found it with my binoculars out of my window and in under a minute I had my scope out on the floor, and with a bit of luck, got it pointing at M27 by just pointing it in the general direction. I wouldn’t be worried at all about the "flimsiness," The flex tube bit is very ridged and I have not needed to collimate it since march. Highly recommended.
  7. I’m thinking about going to the sea to view it, if its clear. I think that pretty much the lowest horizon you can get. I expect it would be a bit difficult to get a south south east sea horizon in Scotland though.
  8. Hello and welcome from me in Newton Abbot
  9. Hello, I know there have been a lot off threads asking about Baader solar film but I feel that there have been mixed responses. I have a 5 inch reflector. Would it be best to have a full aperture filter of an off axis (smaller) filter? I just want a definite answer. I also do not want to waste the film as you only get one sheet and I may want to use it for other stuff (binoculars, another scope) Thank you.
  10. Thanks for your responses that cleared that question up, I understand now.
  11. Hello, I was wondering why the solar system is in one plane. I know the orbits of the planets are slightly different, but why aren’t the orbits random (not all in the same plane). We can see this pattern in the rings of Saturn and the moons of Jupiter. Is there any evidence of the shape of other solar systems? I suppose it must be something to do with the shape of the dust cloud that the planets formed from but how did this flat plane of dust form? I may be barking up the wrong tree here but I’d like to hear what you think?
  12. I think you’re missing the point. Using Books and computers is not goto. They involve the, “you and your brain” bit to find the object. Goto bypasses this bit. I do totally agree with what others have said though.
  13. Hello and welcome from Newton Abbot
  14. Yeh, I did kind of post before I read the post:o That sound like a good idea
  15. Maybe a little difficult to take on a plane, but you could keep the box and take it in that.
  16. Sky watcher Heratige 130p Cheap, Biggish (bigger than the meades your looking at), portable, good quality mirror, quick to set up, no tripod, lets you get to learn the sky (probably more than a goto), takes up small space, dobsonians are easy to use.
  17. That is just amazing:eek:. How do you do it? Its very different to your last one, M53, much more compact with brighter stars. Do you do all of your sketching at the eypiece? and do you use black paper? One again, amazing.
  18. I live in the south west of England so may not get the full affect from it, but it’s not really noticeable at all. Last time I could not see any evidence of ash in the sky and only got a slight layer of dust building up on the surface of cars, but even then it’s hard to tell if it’s actually the ash. A for telescope optics, If the ash is that bad, I expect you won’t be observing anyway because it will reduce the transparency and make LP worse. However, the ash would probably not be too good for the telescope optics. I don’t think it’s as bad as it seems, well not down in Devon it’s not.
  19. Wow that is extra-ordinary. I have the same scope (and it is brilliant), but I didn’t know it could get images that good. Can’t wait to try myself. Again, super images:D
  20. Thank you, Its amazing how light you have to shade to get the negative image very dim. I cant wait to start going to dark sites and start sketching:) after my exams:mad:
  21. Thats a lovely sketch. Looks like you did a good job on getting the texture and brightness right. It would be nice to see it in negative so we can see the details better aswell as getting a better idea of what it looks like.
  22. Hi George, I love the document. I have a 5 inch and am looking in the future to upgrade to a 10 inch. So I can get a better understanding of the views I would get from where I live could you give an estimated naked eye limiting magnitude form where you live? Thank you.
  23. 7 meters long:eek:. OMG. I wonder if its as thick as it shows in the animation.
  24. Thankyou very much. Love the bit with the stars, they just get bigger and bigger. Makes you realise how small the sun is. Its also interesting looking at those stars in the night sky and knowing there relative size. Can you see the biggest galaxy from earth with a telescope?
