  1. it takes about 1 min for a 300mw laser to burst a balloon ....
  2. YES :icon_salut::icon_salut::icon_salut::icon_salut::icon_salut:
  3. monki , i like your philosophy ... spot on
  4. look for a copy of the book ... every photon counts ... astrophotography is a huge subject , its worth a phd at university , i dont think a quick question on a forum will quite cover it
  5. once the shaking stops , look through the ep ?? whats the problem ??
  6. do you remember being about 12 or 13 , and looking through your dads bino`s on holiday , looking at the stars and the moon and thinking wow .... so eventually you get hold of a small refracter , about 3" i think , outside freezing with the wobbly mount looking at saturn and finding your own way about the stars , learning constellations ect , and as you grow older your skills increase slowly and eventually by my mid 20`s i thought about a bigger scope .. so i done my reseach and got hold of 6" reflector , all my years of starhopping and learning proved good as found amazing dso`s with my new scope now im into my 40`s , house ,career , children ect , i think i have the knowledge to use a big scope .... i have done an apprenticship in astronomy long enough . i wonder then how people are faring on here who have never had a scope before and cant tell the difference between an az/alt and eq .. who dont know that focal lenght divided by ep = mag ect ,but have went out and bought huge complicated expensive scopes and eq mounts, and have decided they want to do long exposure photography ! dont get me wrong ..best of luck to those who have ... but judging from the amount of "how do i ..." posts that are on here i think most people would benifit from starting out with a small simple scope and learning how to , i personally dont envy someone with no experience of goto or guiding or ccd`s or polar ailgnment ,eq mounts , or focal reducers ect , ect , buying thousands of pounds worth of kit and then facing a huge learning curve worth at least a uni degree , they must be thinking what have i done ..... anyway little bit at a time is what i say
  7. the F number of your scope is a rough guide to the highset power ep you will be able to practically use .. ie a f8 scope = 8mm ep an f4 scope = 4mm ep any given ep ie 8mm will give different mag in different scopes
  8. dont clean mirrors , ever , unless there is a big piece of stuff stuck to it , dont clean because its dusty , dont clean because it has water marks .... dont clean because it seems like a good idea ... just dont do it , anyone who cleans thier mirrors regularly is damaging the surface/coatings . ps fao tribal im sure the people who make mirrors would go mad if you told them they said it was okay to clean mirrors as long as you dont scrub .... there is some good info on the ziess website , when one of the main mirror makers was asked his opinion on how to clean a mirror or lens (this guy is 77 years old he has made the best opitics in the world for over 60 years ) he said the only thing that should ever touch a lens or mirror is a huff (exhaled breath) . but im sure some of you know better
