  1. Almost identical to this one I went to a local computer shop and explained the house set up and general internet usage (there are only two of us at home and neither of us are online gamers etc) and was recommended the tp-link 300. However, there are many different types of tp-link range extenders with differing types of power, so it's probably best to pop along to your local store and explain to them your own circumstamces etc, so they can advise you which one is best . Even if the store doesn't have the one you need, they can get you in the right ball park to then order online, for example. On a side note, it wasn't necessary in my own case, but you can also have more than one ranger dotted around the abode all linked to the same router. Hope this helped
  2. We have fibre-optic internet and a house of around 300m² and a garden of just over 150m² . Needless to say, there were areas where the wi-fi range slowed significantly. A few weeks back I purchased a tp-link 300Mbs range extender and it works. All rooms seem to be serviced, there is no interference and for my wife's use and my own there is a decent wifi speed so we can work without frustration.
  3. Looking good. Hope you get some clear skies while away, Stu. I've read that perhaps as much as 99% of European populations live under significant light polluted skies, so I guess apart from a few pockets of darkness even Dorset is affected. It's a shame really. I think most folk these day have lost that sense of stillness and awe that should be clearly visible over our heads every night

    Hi from Spain

    Hiya Philippe Welcome to SGL. There are so many excellent imagers here, I'm sure you're going to feel right at home
  5. I think they're both cracking images . However, purely from my own personal non-imager aesthetic, I prefer the second image .
  6. Nice report Stu and good to hear you were able to do a little observing inspite of the clouds. I think TV's scopes in general are some of the prettiest scopes I've ever seen. I love the white pebble finish, the black dew shield, that indestructible, bomber-proof feel about them. In a way, they have an aesthetic a bit like some old classic bike or car. They may not perform quite like the new models in the showroom but they have a class all to their own
  7. When alone at a dark site I want to hear the mosquitoes nibbling at my flesh, and the foot/paw/hoof steps of some unknown creeping near me . When at home relaxed in my own garden there's often nothing better than observing the vastness and wonders of space accompanied with good music expressing that which is inexpressible .
  8. I have used a Telrad on longer tube fracs but prefer Rigel's Quickfinder on my dobs. It sits next to the RACI, doesn't upset balance and is relatively small.
  9. Tweaks to grammar, spelling, adding links, and so on is a very useful function of the edit option but I don’t think we should abuse this option by making drastic edits to an opening post that ends up changing the meaning of a thread, especially when there have already been a good number of thoughtful responses in context of that original post. Editing posts a few hours later for typos is one thing, heavily editing an original post some 48 hours later just doesn't come across as good form or fair-play. Perhaps, in the future, when significant changes to context, meaning and intent have been made, it might just be better to delete the old post and publish a new one
  10. For the Star Discovery 150, I imagine the tripod and mount would weigh around 6kg and the OTA around 5kg - give or take. That is, the OTA ought to have a very similar weight to your 150p. If your 150 was mounted on a rocker box then this box in itself would weigh around 10kg - give or take. The Discovery's 150 should be a very similar OTA to your 150p performance wise. Mounted to an AZ GoTO makes for a a very reasonable priced package. If you wanted to experiment with suitable weight loads before purchase, recall that 1 litre of water weighs 1kg.
  11. Just adding to what the others have already said, the smallest exit pupil depends on a number of factors, notably, seeing, the object being observed, the quality and stability of the telescope and the visual acuity of the observer. As exit pupil decreases one reduces contrast, dims the view and magnifies the imperfections in the optics, the atmosphere and the eye. My own comfortable minimum for bright objects like Jupiter or the Moon is around 0.6mm/0.5mm. After that I have trouble blinking away floaters. However, there is no rule to this. Every eye is different. I have seen sketches from very experienced observers viewing at around 0.2mm exit pupil . Bionic eyes is an understatement. Double stars are the exception. You can really crank up the magnification because essentially at that stage you're just splitting pixels
  12. That's good to hear, Nightfisher You were lucky, its pretty much 100% cloud cover here and didn't even get a peak. Were you able to catch a glimpse of the GRS?
  13. Great buy, Raph. 10" dobs are an extremely nice sweet spot; not to heavy to lug out, breeze to set up and offer up spectacular views. For general viewing in my 10" f5, I observe with widefield eyepieces offering around 60x, 90x, 125x and 180x. Coupled with a decent Barlow or Powermate, you could do all this with just two eyepieces which should suffice a lifetime for most clusters, galaxies, nebulae, and casual lunar and planetary work. If it took your fancy, 50x for white light solar viewing would also be useful and all you'll need is a solar filter made from Baader's Visual Solar Film. If you decide to really get into planetary and lunar observations, you will probably find that it helps to have a nice run of higher power eyepieces. Depending on the evening's seeing conditions, even the difference of just 1mm in focal length - about 10% to 15% difference of magnification - can be surprising. The good news is the eyepieces themselves do not need to be widefields and there's no hurry to build the collection all at once. Again, by way of example, in my own case I use little Orthos. There's certainly no need to go spending loads of money to get decent eyepieces and on this account your best bet is to keep an eye on the secondhand market. Nevertheless, extracting budget from the equation and purely looking at a few eyepiece options which get rave reviews year in year out, we're looking at: Tele Vue, Pentax XWs (perhaps less the 14mm), Explore Scientific ES68, 80 and 100, Meade 5000 UWA, William Optics UWANs, Vixen SLV, Skywatcher Nirvanas, and Orthoscopics like Baader's Genuine. I have found from experience that in the long term it is cheaper for a poor man/woman to buy decent quality eyepieces knowing that these eyepieces will be 'lifers' and will fit a range of different telescopes and retain their market value better, rather than going for quick fix cheaper eyepieces that will eventually need upgrading and will inevitably lose more on the secondhand market. I cannot comment on most of these eyepieces mentioned but at the end of the day, I feel it makes more sense to have two, perhaps three really cracking, quality glass eyepieces, coupled with a Barlow or Powermate rather than a whole load of secondrate eyepieces under performing in a fast f5.
  14. The observing hood I have is quite large, so if you're making one make sure you're generous with your measurements. Here's a handy video of how to put a hood together. Regarding eyepatches. The idea for me isn't so much as preserving dark adaption - although it helps - as it is to cover the other eye that you don't use without screwing or scrunching it up. You'll probably need to practice with a few, adapting according to your needs (sewing in softer material over the plastic/card, extra silky padding, enlarging area etc) until your eye fits snuggly cushioned within the patch, without any stress to the eye itself or muscles and stray light is eliminated.
  15. Aircraft of some sort, perhaps a Chinese lantern . What do you think you saw, Graeme? If you get another chance, a quick video or photo shot would be helpful.
