  1. I got the 6mm TMB Planetary II from them, and am very pleased with it.
  2. That's a really great pic! Can I ask which capture software you used? Also did you use a filter on your spc900?
  3. Just heard this very sad news. RIP Sir Patrick Moore. An inspiration to us all.
  4. R.I.P. Neil Armstrong. Very sad news indeed, the loss of a true inspiration.
  5. Nice to see that this sad news did actually make the headlines, and was covered quite well, including interview with SPM on the BBC 10oclock news. RIP.
  6. Managed to get Venus, Mars, Jupiter and Saturn last night.

    big moon

    I saw it just rising over the roof tops. It was HUGE! I know it's just an illusion, but it was fantastic.
  8. Yep, just come back in, nice to see Mercury, Venus and Jupiter, all lined up.
  9. Appologies if this has been posted before, but there is now an e-petition calling the government to support the Campaign for Dark Skies and help reduce light pollution by reconfiguring street lighting etc. Needs 100 000 signatures to get debated in the Commons! The link is here: Stargazing - e-petitions
  10. I've had the Skymax 127 supatrack since March, and I can definately recommend it. First Light Optics - Skywatcher Skymax 127 SupaTrak
  11. redfox1971 mentioned grail, and there is also the Earth equivalent, grace 1 and 2. These fly a set distance apart doing gravity mapping. They are not listed on heavens above, but you can track them on LIVE REAL TIME SATELLITE AND SPACE SHUTTLE TRACKING AND PREDICTIONS it doesn't go back, so can't check if they were flying over when you all had these sightings, but if you see them again you could check.
  12. Coincidentally, the speed of light was measured in the 17 century using observations of the eclipses of Io.
  13. If you go into the sky and viewing options window [F4], and tick simulate light speed in planets and satelites, this should sort it out. By default Stellarium shows Jupiter as it is at the time and does not account for the time it takes for the light to reach earth, unless you tick simulate light speed.
  14. Thanks for the heads up. Anyone know how to get Stellarium to show the GRS in the right place?
  15. Try mounting the camera directly to the scope without the nose piece. A t-ring should screw to the back of the scope directly.
  16. Yes good advice. I got my Skywatcher Skymax 127 SupaTrak back in the spring, knowing that I might want to upgrade it or get more scopes in time. I didn't want to get everything at once, but rather wait and see. I thought I might wait a year and see how much I actually used it, whether I would get bored in time and so on. Well now, after 6 months or so, I'm wondering if a year is too long to wait? I could get a nice dob for the Autumn, or Christmas. I don't think I'd sell the SW127, it seems like a lot of people on here have this scope, and keep it, just adding other scopes to their list. And yes, just going outside on a clear night and looking up is great, with a pair of bins or not, just learning the night sky.
  17. Nice one! Looks like a perfect fit. Thanks for posting this.
  18. Wow! What can I say - fantastic! Thanks for posting.
  19. Thanks for your kind comments and advice. Well I had a go at making a bahtinov mask, you can print them from this website. Took me ages to cut out all the slots, but I had a go with it and it does work, and makes the focusing procedure much quicker and easier. Barry, yes the SW barlow might be a factor in this (although it is the deluxe one), I've heard good things about the Tal 2x and 3x barlows so I might look into this. Thanks
  20. I used this website to print out a Bahtinov mask. You have to enter the focal length and aperture of your scope and it generates a pattern to print out. I tried this yesterday, glued it onto some card and then spent ages cutting out the slots. had a go with it last night and was amazed that it really does work, really useful for imaging. If I use it alot I'll probably invest in the FLO/Kieth Morris one. You definitely can't use it on Saturn, I tried, just to see, and you get multiple images of Saturn.
  21. Thanks all for the tips. Well, I finally got round to getting a netbook. I went for a Samsung N150P. It's a very nice little netbook, does everything I want really. Seems quite fast despite only 1gb RAM, but you can easily upgrade to 2gb which I might do in the future. It's so handy as it fits on the accessory tray of the scope tripod. Got a chance to go out and do some webcam captures of Saturn the other night. I see what you mean about the size of the avi files! Ended up with over 4gb of data! Lucky it has a 250gb hard drive. Anyway lookout for my attempts on the planets and lunar imaging sections.
  22. This is my first go at webcam imaging. Iv'e had the SPC880Nc (flashed to spc900) for a while, but just got a netbook to actually plug it into. I know Saturn is on the way out now so thought I'd better have a go. This was with a SW127 mak and the SW 2X barlow (as supplied). The avi was 1151 frames taken at 10 fps. Stacked in Registax 6. I'm quite pleased to be able to see Cassini (just about!). I think I'll look into trying to make a bahtinov mask to help focusing, as this is really difficult to do with the webcam. Anyway, thanks for looking, any comments welcome.
  23. You can get the list here. Number 1 isn't too difficult! Also a map here.
