  1. Thats a shame. But its good that we know today rather than having really short notice. A big thank you to everyone who helped get it together, hopefully next year the weather will be a bit better. After saturdays rain we would need to go to mount everest to stay dry John
  2. Complete incompetence in setting up a tent! I'm probably going to arrive around 5ish, so it will be a race against darkness I fear. Is anyone going to bring a tractor to pull us out of the mud? John
  3. I'm wondering about bringing the NEQ6 and 130pds, although everyone's lights will probably dim when it slews! (perhaps thats a good thing, we are meant to keep lp to a minimum) John
  4. It's going to be my first time camping, so I'm not quite sure what to expect! I haven't got a tent yet, hoping to get something this weekend. Are there any types I should particularly avoid? (My student budget will need to take a slap in the face, I fear! ) John
  5. Hi, I've booked! I can only make the Friday night, due to uni schedule. Hopefully I can arrive by lunch time on the Friday though and stay on until after the hog roast on Saturday evening. Clear skies! John
  6. Wouldn't it be funny if budget astrophotographers from M31 are saying the same about the Milky Way right now..... John
  7. Hi Stu, its good to be back! I've looked at the 150 several times before, reviews seem to be a bit mixed about its performance at higher magnification. Otherwise though, it seems to fit the bill quite nicely as its well within the size and weight capability of the neq. Have you ever used one? What was it like for general viewing? Its very tempting, and just down the road from me.... but I really want to tread carefully and go for performance over looks, I have a chronic weakness for fracs which must be kept in check! John
  8. Hi, Well, first a bit of an apology, I haven't been active on here much recently, my 1000d is beginning to breathe its last so the imaging is on hold for a year or two until I can invest in a proper, good camera. Meanwhile, I'm doing visual observing and planetary imaging with my 130PDS and NEQ6. I've decided that I should be able afford a budget-ish (roughly <£300) second scope for visual and/or planetary imaging, so long as its the last astro purchase for a year or two. I really want to get a better view of the Mars 2020 opposition than I did last year with the 90mm frac. I live in b4.5 skies so I'm not averse to some deep sky observing capability too, although my 130PDS does a good job on widefield targets. I'm happy to use the 2nd hand market, although I'm aware that some scopes are more common on astrobuysell and SGL than others. What sort of scope would you folks recommend? I don't know if I should go with a dob or an OTA of some sort for my NEQ. I've owned both newts and a frac before, but I really don't have the experience with different scopes to work out whats best for me. There's also the possibility of a more portable setup, but with uni starting next month I'm not convinced Ill have the time to drive out to dark locations and stuff. (Unless I can find a really nice setup going cheap, that is! ) Clear skies! John
  9. Wow that is just fantastic! You've done a great job of the processing there. John
  10. Wow those are really nice echos! It would be so cool to map their directions, your "pings" seem to have far higher resolution than most. Its fascinating the way that they seem to split up on different frequencies. John
  11. Nice shot! That was some lightning, thankfully it wasn't loud, being really high up amongst clouds. We had (at Chippenham) around 3-4 flashes per second during the best 20 mins (not counting the flickering from each flash), the most I've ever seen. The sky seemed to be lit up by a set of failing LED strip lights, quite disorientating. John
  12. Hi, Wow, there really are some nice photos on this thread, definitely worth reading! These were a couple of quick shots from Monday "morning", Saturn with the NEQ6 and ASI120MC. 1. Saturn from a video of around 15k frames, with 2x (dreadful) barlow. Its a small image, really I could do with getting a decent quality 3x for this kind of stuff, still using the one that came with the explorer 130! 2. Again with the Barlow, this time a single 5 sec exposure to show Saturn's moons: (L) Dione, (R) Tethys, just under the planet is Rhea, and under that is Titan. I was able to see all four visually with the 6mm eyepiece, although it was a bit of a struggle. I purposely didnt look at the position of the moons beforehand, its so easy to imagine faint dots! Clear skies! John
  13. Hi, My 1st entry to a SGL competition, I hope this is sufficiently astronomy-ish . I took this one evening in Appledore, North Devon. This is the view across the river estuary looking north-northwest, about 90mins after sunset. The whole northern horizon was dominated by really bright and sharply defined noctilucents alongside Capella, and the colours and contrast in the sky were the best I've seen. The sunset afterglow is exaggerated by light pollution from Braunton and Chivenor, hidden behind the dunes on the other side of the river. Eos 1000d and 55-200mm lens, on EQ2, electronic shutter. Lens set to 55mm, at f/4.5 4 sec exposure, ISO400. Some light processing in Gimp and Star Tools. John
  14. Hi Stu, Thanks! The galaxies werent easy at all, i would agree than M82 is the better of the pair, visually. Oops, my error! The optician says my eyes are ok but they would have to be very sharp to see Hadley Rille at 25x I think i put Hadley in the wrong section -- if i remember right I tried to spot it with the 28mm eyepiece, but realised it was far too low mag, so switched to the 6mm in order to spot it. (Which gives just over 108x). The crater was quite easy to spot, but the rille was only a hint of a shadow near to the mountains. There is a chance my eyes were making it up, or got confused with shadows from the mountains. I'm pretty sure it is possible to spot with me setup though, this was with the same scope and my asi120 on a night with poor seeing and a bad lighting angle. Thanks for pointing out that mistake. John
