  1. Nice one guys, sounds a lot cheaper than the yank version!
  2. Having seen the price of ready made dew shields and how simple they look in contrast to their hefty price tag, can anyone point me in the right direction for materials to make one myself? I have no idea about material type (guessing neoprene), thickness, fastening methods etc.... So any help is appreciated.
  3. No worries, I found a thread eventually that specified the springs, but for anyone wanting to know, you need three springs with 1.6mm wire gauge, 13.72mm OD, 12.7mm free length, 4.2 coils. Can be bought from spring master or Lee springs.
  4. Yep, the problem of weak primary mirror cell springs for these scopes still exists, and we are in the hunt for some replacement springs to improve longevity of collimation. Obviously bobs knobs sells these, and RVO are the only supplier in the UK, but they have been out of stock for the past month and we really need these now. Does anyone know what type of compression spring we need to replicate these items because £17 is a lot for three springs tbh, and if we can get these cheaper from a local chandler or something then all the better....
  5. It's ordered btw, my name isn't fin, it's Dan lol.
  6. Its not overally detailed mind but works really well with a narrowband filter attached. Quite hard to orient the scope when Cassiopeia is so high up this time of year.
  7. Ain't bad, although the nearby town can and recent nighttime building works can scupper certain portions of the sky
  8. We have seen it in our pisky 5"er, clear skies mind and near zero light pollution
  9. After weeks of poor weather, high humidity and strong winds, we finally got some time out with our old faithful Skywatcher 130P on the Isles of Scilly. It is so rewarding to have the constellations of Orion, Gemini, Taurus and Cancer up this time of year, although we do have to say good bye to some summer constellations that have provided us with a huge insight and wealth of knowledge of the night sky since starting out back in April. We will soon be upgrading to a Revelation 12" dob come next month (hopefully) to find the more elusive nebulae and galaxies, but our moderate 5" scope has done
  10. The straight wall is awesome to see, as are the craters within Clavius. It's amazing just how different the likes of Tyco and Copernicus are between a gibbeous waxing moon and a full moon. Great pics man!
  11. Relatively easy to find, depending on the eyepiece being used (biggest one you got). Find the Saucepan (Big dipper, plough whatever), locate the stars Phecda and Dubhe diagonally opposite each other in the pan itself, these will be your pointer stars. Using the distance between these two stars as one step, step outward from Dubhe in the direction of the pointer you made until you find two very faint stars (dUMa & HIP 47594). Centre your eyepiece onto the star closest toward Dubhe and you should see M81 & M82 in that FOV, you may need to pan around slightly but you should find them.
  12. Thanks for all the input, that website looks particularly interesting, in fact I may have come across it before but totally forgot about it... That's what I like about astronomical sketches, they capture exactly what you should be expected to see through a scope's eyepiece, as opposed to a photo (or series of photos stacked) that gives you an image that your eye cannot see.
  13. I currently have Turn Left at Orion (for home telescopes) and it is one of the best purchases I have made in terms of an astronomy tool, but I can't help think that once we get the bigger 12" scope the book will have reached its limit of giving us faint DSO's to observe. What other books can I buy that are written mainly for the viewing of objects through larger scopes? Stellarium is obviously a useful tool but a) not all objects have an image to check against what you are trying to observe, and it lies with apparent magnitude of certain objects I find so you might skip over some because of
  14. Cheers for the tips guys, duly noted for when we get the next scope, which is hopefully going to be a Revelation premium 12" dob so can take a 2" eyepiece. I like trying to resolve the fainter and larger objects in a smaller aperature as well in a wide field of view, it is pretty spectacular when get your eye in and the conditions are perfect. But I think my desire for more detail outweighs that argument for me, I would also like to spot low magnitude DSO's as well. Of course, we could always keep the 130p for lunar observations, larger nebulae etc... But we need the money to part fund the
