  1. Yes the response was that the new MPCC will be unavailable until the end of this month (October). Official web site now says: "This product is temporarily not available for ordering. The vailability date will be at the end of february 2013."
  2. Well Pegasus and Orion aren't a very good example as I can clearly see all main stars of Orion, including the six "bow" stars (π1 - π6) and all the "antenna" stars (χ 1-2, υ, ε and μ). I'd rather be interested in using captured image to measure "magnitude per square arc second" - at least this is the description of what that gadget does.
  3. Is there a way to measure the sky quality of your observing site without any specialist instruments? I was looking at one of those "Sky Quality Meter" gadgets and thought if there is a simple method of perhaps using a DSLR to determine how dark or how light-poluted the sky is?
  4. Narrow band filters only let through a badum-tss! very narrow band of light. So you don't need a light pollution filter in use with say Hydrogen alpha filter. Otherwise they would overlap and H-a would still block most part of what CLS lets through.
  5. I emailed Baader and got a response from (I suspect) mr. Baader himself. :eek:
  6. I don't want to hijack your thread algady but I'll use this opportunity to ask a question that might be useful for you too. Are there any physical, optical, theoretical limits where a 1.25" barlow is simply not doing enough of a job and where 2" barlow is essential? Are the any criteria (primary mirror diameter, focal ratio, imaging object dimensions, etc) that will cause vignetting with a 1.25" barlow and the 2" barlow will take that out? The question is purely for photographical use with a DSLR, 8" f/4 Newtonian.
  7. You gotta keep moving from time to time, don't just sit or stand at the scope. Your fingers and toes get cold and whole body numb in winter or autumn nights. Silly jump or run around the telescope will get eyebrows raised if someone notices you but it will get you warmer.
  8. Why did you need 8.8 and 9 mm eyepieces though?
  9. Didn't you put up a video on youtubes? I watched an unboxing of two ES eyepieces the other day. Er, yes you did. Got confused with FOUR eyepieces in the picture.
  10. So which focuser position is in and which one is out? In other words, do you begin with the focuser fully extended and slowly shorten it towards the tube, or do you start with the focuser low and then rise it up?
  11. I'm 24 degrees East so the eclipse should be seen according to Wikipedia. UK also falls into "visible at Moonrise" category.
  12. I wanted to see how the Moon appears in this year's (November 28) eclipse but the Sun doesn't cast a shadow on Moon surface. Now I do remember that a previous version of the software did simulate Sun's shadow on the Moon. I'm using the latest version which is 0.11.4. Any ideas what might be wrong? Any place else where to see how great a part of the Moon is eclipsed?
  13. Surely someone out there has to have the visual set and Hyperion eyepiece. :confused:
  14. Can anyone confirm do the fine-tuning rings for Baader Hyperion eyepieces work with Baader MPCC for visual use? Are they the same 14 and 28 mm pieces of metal, in short?
