  1. Does anyone know how much it costs to get in and what time the doors open on Friday? Looked at the website via my tablet but couldn't find any links on the homepage! Thanks
  2. You could also try http://www.skymaps.com/skymaps/tesmn1610.pdf
  3. Depends how deep your pockets are but I would have thought https://www.firstlightoptics.com/clearance/hubble-cassegrain-reflector-telescope.html would do a reasonable job and once you finish looking at the moon it should be good for deep space objects too
  4. I personally use one of these https://www.firstlightoptics.com/moon-neutral-density-filters/variable-polarizing-moon-filter.html which I prefer because the moons brightness varies depending on how full it is or what magnification I am using (higher magnification also dims the view)
  5. This may sound like a stupid question but when you set up your gear for the evening have you checked that the tripod is level with a spirit level? If the tripod and subsequently the mount is not correctly set up you can do as many star alignments as you like but will you never be able to correct any draft issues until the tripod is set level
  6. Also a very quick way to get your optics cooled down I geuss!
  7. If the object is not too high I find sitting in a car with the binoculars resting on a partly opened window offers a good cheap support. Altitude can be adjusted by moving the window up or down as needed. It really does make a lot of difference to what you can see by supporting your bins
  8. Am I the only person here seeing an opportunity to rebadge small C02 extinguishers as primary mirror cleaning systems.....dragons den here I come!
  9. I would have thought at the speed the dry powder travels at from a discharged extinguisher that it would scratch up the ultra thin mirror coating therefore foam is probably safer although messier! Plus I was under the impression that foaming cleaners lifted debris away from the surface?
  10. Not sure why that quoted the same thing twice?
  11. Just make sure that you don't pick up a dry powder extinguisher by accident! Lol
  12. Having seen what grows in my dehumidifier collector I would have thought urinating on your mirror would leave less bacteria and nastys on its surface!
  13. I'm a little confused about the 3 extra springs fitted where the locking screws were. Are they just floating there with the 3 locking bolts preventing them from falling out or did you drill and tap extra holes in the mirror cell? Doesn't this make collimation more complicated?
  14. I have to agree that 90mm is the smallest size aperture to get good views of planets and the moon. My first telescope was a skywatcher evostar 90 and can make out 3 or 4 bands on Jupiter and just about make out the outline of the great red spot on nights with exceptionally good viewing conditions. On the moon it is extremely good. If you ate new the astronomy and on a budget a good start would be to use binoculars but as far as the planets are concerned the best to expect is to make out Jupiter about 2 or 3 mm round and the 4 moons as small dots. It would be a good idea if you could find a local astronomy club and have a look through some members equipment to see what to expect before making a purchase
  15. Think I will invest in dew heaters this year. Reason being that unless you have a method of dew removal once it forms on your optics (and it will) the only thing to do is pack up and go home
