  1. Good work Vicky - the double double is always a satisfying sight. With steady air, they make a remarkable quad system in the eyepiece. Ed
  2. Brilliant kit - good luck with your imaging. Ed
  3. Bad luck there Yorkshire, OK down in East Devon, but clouded out by 9:30PM, just as I was getting on to Jupiter. Excellent planetary nebulae before that however, and a stunning M13. Better luck tonight perhaps. Ed
  4. I use this mount a lot, in a suburban backyard (terrace house). The neighbours haven't yelled at me yet! I think a baby woke up once and started crying, but I can't be sure it was the mount that caused the tears. I don't find the slew noise intrusive, and it is silent once tracking. Ed
  5. I enjoyed your report. Thanks for writing this up and sharing it with us. All the best. Ed
  6. Hi - agreed the Mak would be great for planets; it's difficult to find a scope that does both things - deep sky and planetary. In fact, I don't think there is one! The combination of a wide field refractor, and a Mak is nice - gives both options, but of course raises the question of cost and storage space. Ed
  7. Hi Amy - if your reflector is taking up too much space, it sounds like a short focal length refractor is going to be best. However, while it will be good for clusters and dsos, it won't be that good for planets due to colour fringing and lack of magnification. You could look at something like this: First Light Optics - Skywatcher Startravel 120 (AZ3) If you need a smaller version of this, there is the ST102. It will definitely be a compact, easy to store tube. I use the ST120 and it's very good for clusters and dsos. All the best. Ed
  8. Hi stringbean - doing astronomy is a real learning process, and often the subtlety of it takes a while to appreciate. Hang in there and it will grow on you. Good luck with the hobby. Ed
  9. Hi there - the nights down here have been very warm. For example, observing in shorts and t-shirt on Friday night at 11:30PM! In late September....! There has also been a huge amount of moisture in the air, which has made transparency poor. Agreed - cooler nights and drier air will help a lot. Should make viewing Jupiter a more rewarding experience. Early morning viewing can be a treat - just before dawn in mid-winter can often be the best seeing of all. Great for the early risers amongst us. Ed
  10. Stringbean - your mag. with the 32mm ep was 1200mm/32mm=37.5 times which would give a small image. Your scope should be well suited to planetary observation due to long focal length (1200mm/150mm=8 - i.e. giving a focal ratio of 8 or f8). Long focal lengths suit planetary viewing - for example my Maksutov is f12. I think your difficulties with magnification were probably due to poor sky conditions more than anything else. You may be more impressed when you can view Jupiter when it is higher in the sky, and has gained more declination. You should be able to achieve around 150x magnification with very good seeing conditions. It is difficult to achieve anything more than this magnification wise unless the sky conditions are exceptional, when you may get around 200x. Hopefully I've got the maths right! Ed
  11. Great image - good contrast with dark sky and bright galaxy/stars. Well done.
  12. Hi Stu - I'm hoping for better images later in the year, and hopefully in subsequent years as the planet gets some northern declination. I've got all the bits and bobs now to take advantage of those good nights when they come along. Good luck! Ed
  13. Thanks for the encouragement - I may well start a thread to get some feedback. There's loads of experienced people on SGL who chip in with great advice. All the best. Ed
  14. That's a really nice idea - very straightforward! Should be very easy to set up and get observing. Ed
  15. Hi there - what a great thread, thanks for sharing this project on the site. Your recognition in S@N magazine is thoroughly deserved. I'm working on a design of my own at the moment, and it certainly keeps the brain cells working to try and sort out all the details. All the best. Ed
  16. Hi there - spent last night looking at Jupiter with the MakCass. The conditions weren't very good, and it was difficult to get a settled image. Best ep was a 14mm Plossl (giving around 128x), which gave a sharp image and some details in the equatorial bands. Some subtle details towards the poles from time to time. A 26mm Plossl gave a fine overall view (giving around 70x) of the moons and planet. Further magnification with a 9mm Plossl (giving 200x) didn't really help the image, except at moments of good seeing, which were very rare. All in all, pretty typical for this planet! Thanks. Ed
  17. That is a very nice telescope - thanks for sharing the pictures. Ed
  18. Perfect!! Will track this down - it's just what I want. Thanks. Ed
  19. Hi - the disc seems a bit big for my needs - I probably need something about 7" in diameter as the scope isn't going to be big. I just need an offcut or scrap. Will keep my eyes open. Thanks again. Ed
  20. Hi John - that's helpful, so there needs to be a bit of 'texture' on the disc. I'll look at the TS site. Thanks. Ed
  21. Hi there - I'm interested to know whether a bearing can be made from a piece of acrylic and PFTE/Teflon. I am thinking of making a dob mount using an acrylic disc (say 2-3mm) and PTFE pads. Any thoughts. Thanks. Ed
  22. That's really helpful. I am hoping to start a diy dob project soon and I was wondering about the shroud. I was planning to use black ripstop nylon, and I had a feeling it might lead to drops of dew running down the material and into the mirror box. Might need to have a think about this. Ed
  23. Hi - I was on the Lleyn Peninsula a couple of weeks ago, and the skies were great. Really excellent views of the Milky Way and I was able to find a lot of NGC clusters that I had never tracked down before (in binos). I can't recommend a particular site, but you might want to look around the Aberdaron area for really dark skies. Ed
  24. That is very smart! Great set up. Ed
  25. Hi Eyepod - great image of Jupiter. Keep up the good work. Ed
