  1. Nice pic, I'm no expert though, took this moon photo with my smart phone at x30. Used a moon filter then edited it to mono as it was green. I was quite happy with it. Have you tried higher resolutions, this is where my smartphone started to let me down I think.
  2. I picked up a few of these objects myself last night, although I must say galaxies elude me! Beta monoceros a nice triple.
  3. After not observing since last May I returned to the back garden between Xmas and New Year and have been sitting on my hands ever since! My records of last January show two or three sessions a week. I was very excited to have a superb clear sky last night with really good seeing, but note it will cloud over later and set in for the week. Well, absence makes the heart grow fonder, so each observing night is at least a treat!
  4. Ahhhh takes me right back...ten weeks!! My first scope and loving it when I get a chance to use. Good tip about adding a weight as the vibrations at high magnitude and high winds take some settling. Sure there's a 10kg kettle bell around here somewhere...
  5. I've had two goes at Jupiter (over my neighbour's house) and I saw more the second time. With a 150p with 10mm x 2 I'm at x150 magnification and its like the little pea picture posted above. Id say the seeing was similar each time but my second viewing was much longer and I perched on my ladder. After 45 mins I had seen the two equatorial bands and two bands either side of that. I also enjoyed seeing the moons being different colours (although I haven't checked if that was right or my imagination). I'd say you have the same questions as me but advice on this group does bear out. I think a good study of Jupiter's bands in a diagram or proper photo helps the eye know what is possible so its more likely to 'grab' the detail when it briefly presents itself. I find the same with star colour, Betelgeuse now seems incredibly red to me compared to a couple of months ago. By the end of the year I'll be naked eying Io's shadow transiting
  6. Great advice and support as ever I found this whole thread really useful
  7. I observed Jupiter for the first time last night with my 150mm newt. My max magnification is x150 with a 10mm and x2 Barlow. Whilst it brought a big old smile to my face as a first experience and the layout if the four visible moons was fab I did think it would be bigger in the eyepiece. I could see the two dark bands around the equator but given the size of the image I can't see how id have seen much more detail given the size of it, especially like that lovely sketch above. Any thoughts on the size in the eyepiece?
  8. Thanks Olly I'll certainly check that out
  9. Our own local black hole at the centre of the Galaxy seems to have an estimated mass of 4,000,000 solar masses so would be a fair size but still small on an astronomical scale.
  10. I think you are referring to the singularity there as having zero size. In the book the radius of a black hole is defined as the distance from the singularity to the event horizon which is called the Schwartzchild radius. The radius is calculated as 3xMass in solar masses as kilometers. So a star that leaves a remnant core of 5 solar masses after supernova could form a black hole with a radius of 5x3km or 15 km. Still pretty small! Newtons laws of gravity will start to break down at 3 x Sch Radius rather than at the event horizon which in this case would be at 3x15=45 km. So you'd feel a bit funny before you got to the event horizon!
  11. C2A looks good! I like the observation planning feature.
  12. I'm now obsessed by astronomy having bought a scope but of course have only managed four observing sessions in the last month. Well being a data and detail nerd I had to do something to fill my time so I bought 'Astrophysics is easy!'. I must say its a fascinating read and will really enliven my next brief sighting when the clouds clear. Best of all its not shy of including all the formulae and maths. Anyone fancy calculating the width of a black hole from its mass? Thoroughly recommend it, are there any other books people would recommend?
  13. I love Stellarium, its free and awesome. Is it really worth paying for the commercial planetarium rivals e.g. Starry Night? What more can they do?
