  1. If you have the right kind of phone and tablet cases you could consider getting a sheet or two of Rubylith - available on Ebay. This will not "cling" to your phone and tablet screen but cut to size and slipped into a suitable case it will give good filtering but will still allow your touch screen to work. I used this solution for a couple of years before Apple introduced colour filtering in iOS10. Unfortunately android haven't got the same facility. One other though is to try Rubylith with a spray-on repositionable adhesive - same stuff they use on post-it notes although I've n
  2. Just been out after this one with the 18" and bagged it after a bit of a search. The nearby mag 6 star was the key to locating the galaxies and the SN was definitely there. Thanks for the heads up.
  3. Hi There If the finder is still available I would like to buy it. Kind regards Rob
  4. It's also worth considering exit pupil when looking at competing widefield eyepieces. This for me is where the 31 Nagler and 35 panoptic lose out to the 21 Ethos. It's not really a problem for the 120 ED but as soon as you start ramping up the aperture and dropping your focal ratio you very quickly get to the point where you need to have very young eyes to accommodate the exit pupil on the Nagler and Panoptic. As these eyepieces tend to be a "forever" purchase it is worth considering the future (or in my case the present)
  5. I'm up on Friday - Pitch 398 Red Not convinced there's going to be much viewing so packing plenty of beers and a good book or two. Rob
  6. I do leave my Dob and EQ mounted Newtonian outside overnight - sometimes for several days but not permanently. I suspect that unless you regularly (i.e. daily) uncover the scope to let any collected condensation to evaporate your mirror coatings are going to suffer. Thanks to air pollution the dew that will collect on your mirror is mildly acidic so unless you keep the scope angled to ensure run off your mirror is going to suffer. If you are set on keeping it outdoors I would recommend a cover from Cygnus Astro http://neilross758.wixsite.com/cygnus-astro-covers. I purchased one at the Kel
  7. I use a focusing headtorch https://www.maplin.co.uk/p/sensor-head-torch-a78kf with 2, 3 or 4 circles of rubylith layered over the lens. The number of layers depends on where I am. In my garden -2 layers Astro Society Observing session - 3 layers Star Party - 4 Layers The focusing helps as I can concentrate the beam when I need to read something and diffuse it when I'm walking around.
  8. Well I must admit we do have a lot of felines in Surrey
  9. Have you thought of using a Powerline Networking Plug to get data down to your Obsy? http://www.alphr.com/realworld/388024/how-to-get-broadband-to-a-garden-office
  10. HI Gina Have you got mains power run to your Obsy?
  11. A recent campaign by a Surrey resident backed by the "usual suspects" who seem to jump on any "it's an outrage" bandwagon has resulted in the streetlights staying until 01:00 instead of 00:00. He cited elevated crime rates in selected areas of Surrey as his justification despite the figures showing no overall correlation between crime rates and the switch off. https://www.getsurrey.co.uk/news/surrey-news/surrey-street-lights-switch-off-13852866 It seems that Joe Public is scared of the dark - probably watched too many Horror Movies!
  12. Apologies WonderStar I should have marked this as sold
  13. Spotted it in the 18" Dob using a 21mm Ethos at the Breklands AS Star Party in Suffolk on the Sunday night but it's wasn't an easy spot. It was really dark but the seeing wasn't the best, faint fuzzies were not at their most prominent.
  14. I use an open weave PVC ground sheet. http://www.jacksons-camping.co.uk/general/ground.htm secured with some of these https://www.motorhomeshop.co.uk/apg0110-groundsheet-peg this lets any rain or dew straight through but protects my Dob base from the ground nicely. It's a bit more expensive than a standard Tarp but much harder wearing. Its great for putting down in front of tent entrances or inside awnings as well.
  15. I'm attending the Kelling Heath Star party this weekend and will be bringing my Skywatcher NEQ6 mount and tripod to sell. I will be on pitch T372 Red Squirrel Area from Thursday evening until Monday morning. The mount is in good working condition and comes with all the usual bits and pieces. There is an extra power lead and a Mains PSU as well. The 2 counterweights show the usual wear and tear to the paintwork. The bottom Latitude Adjustment Screw has been replaced with a hex head bolt and the mount comes with a ratchet spanner to adjust. I have updated the firmware on the
  16. Booked up for my first time at this event. I've heard good reports from colleagues who have attended in the past and am looking forward to it.
  17. I will be taking my Outwell Bear Lake 4 up to Kelling for the seventh time this autumn. It is a fabulous tent - big enough for my family of four but can be put up single handed. The poly-cotton fabric moderates the fluctuations in temperature that I use to suffer in my previous nylon tent and also muffles the sound - not a problem at star parties but a blessing on family holidays. The downside is that it is quite a heavy beast. It has a zip in main groudsheet and I use it with a footprint groundsheet as well and a side extension. It feels palatial when I'm in it on my own. I'm 6'4" a
  18. I would suggest asking your question on the Simulation Curriculum Community Forum. https://support.simulationcurriculum.com/hc/en-us/community/topics I would include information on which version, platform and hardware you are running the App on as well.
  19. I have used an Orion Optics VX10" Newt on a Skywatcher AZ EQ6 for the last 3 years and its a very nice combination.
  20. I use a USB/Serial converter on mine and have had no problems updating the handset.
  21. It's a very similar event to the Autumn one. As red dwalf point out the nights are a couple of hours shorter but the format of the event is much the same. It isn't quite a popular as the Autumn event and therefore it's easier to get a decent pitch but there is usually a fine array of equipment on show. I'll be on Red 303 in you fancy dropping by.
