  1. So you're the one! Hrmpfff! I am afraid it seem to affect us world wide though. :-) What a beauty though! Congrats!
  2. Congrats! Nice! Yeah, as cantab says - low power is king on these wide-field objects. Larger magnification = smaller field of view. The details will not visually stand out at any magnification really, it takes long exposure photo to see any of that. Well worth adding, it also in general take pretty good sky conditions to be able to crank up the magnification with maintained quality. I usually work my way up from the smallest magnicifation to the one most suitable for the evening - and of course also let the observed object decide which EP/mag to use. Next challange could perhaps be M33. Harder to see but all of a sudden it will pop out!
  3. Hi Nick. Tnx. Bought a complete set of Burnham's around the millenium shift but it's really only lately I have "discovered" the books. They are truly a treasure chest and well worth digging deeper into. I noticed, when ordering the Webb Society's "Vol 1 Double Stars" - that they also have a wide range of handbooks. Considering to get the complete series. Sometimes you just miss the pre-internet days, when good reference books, star parties and magazines were the only way to get updated and tuned in on the latest. I just love sinking down into the recliner on those cloudy rainy nights with a good reference book, to do some research, and to take another guided tour into the deep unknown. With a fire lit up and perhaps a whiskey on the sidetable, the experience is pretty darn close to the one behind the eyepiece! What a great hobby we have!
  4. Perfect Ian! Appreciate yr reply. Been sending variable star reports to AAVSO for about 4 yrs, but where do you submit the double star reports?
  5. Tnx wxsatuser, great info. Have CDC but rarely use it, I find the earler versions much better - the last one is very sluggish. Perhaps the WDS can be downloaded and added on the older versions as well. Will check it.
  6. I forgot all about this page, had it boomarked as a favourite years ago, providing free double star charts: http://www.geocities.jp/toshimi_taki/ Lots of goodies! Charts under "Tools for observation"
  7. Hello again. What is the Eyepice requirement to get going and to be able to do measurements of acceptable quality? What would be a good mininum? Been looking at the topic titled EP, Meade 12 mm. Also read som articles with homemade micrometers, ranging from basic homemade cardboard covers to modified EP' with 360° scales. Will the Meade EP replace the latter? Cheers
  8. Thanks a million. Great. However, I checked E-bay and found this one: "Webb Society Deep-Sky Observer's Handbook: Vol. 1, Double Stars" for a couple of dollars and I bought it a few minutes ago. It will do for a while I hope. Atlases... I have two different, Sky Atlas 2000.0 as well as S&T's Pocket Sky Atlas. They mark the double stars. Is the Cambridge Atlas different in any way? Sissy Haas book... been looking for it for a while, but it seem sold out everywhere! I am thinking this book is one big compilation of double stars, presented by lists? I have Sky Catalogue 2000.0 Vol. 1 & 2. Volume two lists a lot of doubles, maybe this will do as a reference as well. Cheers
  9. Hello splitters! Can't make up my mind on what book on double stars to buy, there seem to be two very popular books right now, considering one of them: 1) James Mullaney; Double Stars and Multiple Stars, And How To Observe Them. 2) Bob Argyle; Observing and Measuring Visual Double Stars. I would like to lay my hands on the most complete book. What are the pros and cons for the two? At the moment, only kept busy with splitting stars visually but plans are to do more serious studies up ahead, measuring separations and position angles - perhaps even imaging. Thanks.
  10. Worth adding... once outdoor, avoid observing objects closely above house tops - this will cause same blurry vision in general. Same thing may be experienced escpecially in evening sessions when the air has cooled down faster than the ground, I always prefer early mornings when the ground have cooled down to a higher grade. One last thing; let yr telescope cool down before using it, let it sit outside for atleast 30 mins if its kept indoors. It makes a world of difference! Over & out /Spica
  11. Yeah, it's really a killer to stay indoors when the warm air rushes out the window causing nothing but turbulence and headache! This has terminated many newbie-interest and definately put a lid on the fun for many. Including myself once upon a time. I got very frustruated I recall, not being able to reach focus, and disappontedly left astronomy for nearly a decade! Unfortunately there were no internet around to ask these kind of questions back then in the early 80's. Good luck in yr next attempt now, just bear in mind that you may also experience turbulence while out in the open. There are not generally many nights over the year when the conditions are really 100% perfect - but often good enough to give you that kick. If you have a smartphone, try downloading "Astro Panel"... its a neat little free app that will display transparency & seeing (two factors amongst a few to consider before yr observing session) on your site. /Spica
  12. Usually in my backyard which provides lim mag 10.7 at darkest portion of the sky with the 5". Have abt 10 min drive to mag 12.4 with the same scope. Thats good enough for me. Wheon graze alert now though, and willing to drive a hour at most for this.
  13. Hi. A little curious how the selection is made for the stars in the software LOW.... (and for Lunar occultations in general). The moon occults stars all the time, but it seem like only some are of interest? Atleast only a few are used in the output anyhow, and some evenings I get "No occultations tonight" even though there are lots of 'em. Is it by a magnitude limit or perhaps by a angular star diameter? Can anyone fill me in? Thanks
  14. Very nice picture indeed! Congrats! I have also looked at this comet visually a few weeks ago with my 5" @ 25x, and never saw any tail either. I never tried with higher mag, but I do believe that wouldn't have done any change in this case.
  15. Me too have observed in Canada, never faced a bear though, but I was also warned. However, wanting to see bear in broad daylight, I was hinted to go to the city dump and spend the day there (sitting inside the car) as that was the most likely place to see a bear, looking for eadible houshold garbage... none seen, and as of today I still don't know if I was a victim of cruel Canadian humour or not...
