  1. I don't disagree with you but I don't agree eirher. The 200p is in many ways a better scope . You see more detail. its easier to use straight out of the box and its cheaper. However you are absolutely right that that doen't make it necessarily the best scope as you pointed out peoples needs are different. I don't drive and I can't view from home so my gear needs carrying this rules out the dob and by the way the 127 skymax as the mount tripod and battery makes it too heavy for my 3/4 mile walk to view. So I do agree that the dob isn't necessarily the best scope and by the same token neither is the skymax and for similar reasons neither is my ts 80x480 triplet which although double to triple the price of both scopes doesn't from a city site show as much as either the skymax or dob. All scopes are a compromise so there is no stand out best scope just a best fit. Which of course is where you came in and something I do agree with about getting as much info as posible and listening to what is being said. The best scope is a mixture of affordability, usability, portability and performance where your priorities lie depends on the order and weight you give each attribute. to my eyes the 200p out scores the mak in affordability , performance, tied on usability and is slightly less portable. So my definition of best scope is" the biggest scope that you can use easily and comfortably in all the places you are likely to use it" for some people that;s going to be an 18" dob in the back garden for others its going to be a 70mm achro they have portaged into the countryside, So is the 200p the best scope? No. but it can be and likewise for the skymax or the celestron 70 or edge 14" on cpc et al
  2. this tripod is rather good but you will need a better head for it http://www.firstlightoptics.com/tripods/horizon-8115-2-way-heavy-duty-tripod.html
  3. when you factor in the amount of time I am getting to use this stuff it's starting to look expensive
  4. That is correct not all goto alt/as mounts have this function but the se mount does
  5. the celestron c5 spotter comes to mind it cools quicker than the 127 mak and its a bit lighter it holds collimation well no ca yes at f10 its narrow but stick a focal reducer and you have an f7ish 800mm scope which appears ti widen it a little i find it better on planets than my 80x480 triplet also better on all but the wider dso;s i will be at sglx if you want a look
  6. if you have a smart phone or tablet sky safari is a very good app and if you can't get to really dark sites more apparture is the next best thing
  7. i am so sorry I missed reading this until after i had posted the altaz goto mounts will not be very usable for you as they will be difficult to align from indoors. the c5+ on astrobuy/sell can be used as a manual alt az so that could be used and have you considered the heritage 100p or 130p or virtuoso range http://www.firstlightoptics.com/heritage.html
  8. the celestron nexstar 127 slt http://www.firstlightoptics.com/slt-series/celestron-nexstar-127-slt.html or skymax 127 synscan http://www.firstlightoptics.com/az-goto/skywatcher-skymax-127-synscan-az-goto.html may be good for you or this from astrobuy sell http://www.astrobuysell.com/uk/propview.php?view=92160 or if you must have an eq mount http://www.firstlightoptics.com/omni-xlt-series/celestron-omni-xlt-127.html
  9. the 1100d is fine for astrophotography like ronin suggests if you have the money for a 600d and a synscan upgrade you would be better off getting a used heq5 and not make thing harder for yourself trying to guide such a large scope on a small mount or take the money you would have spent on the 600d and get a 130pds and coma corrector to use on the eq5. Firstl point of call should perhaps be this http://www.firstlightoptics.com/books/making-every-photon-count-steve-richards.html it tells you what you need and more importantly why it may save you from some costly mistakes
  10. I agree with Ronin about the mounts and scope.the 130pds on an eq5 is bit more doable imaging wise it;s still a bit of a handful as the eq5 isn't really an imaging mount but you can get product out of that combo
  11. the link works for me its a clamp that fits on the counterweight shaft
  12. something like this http://www.teleskop-express.de/shop/product_info.php/info/p229_TS-Piggyback-Cameraholder-for-D-20mm-Counterweight-Shaft.html
  13. if its photo's you are after leave the etx as a visual scope and get yoursef a good mount ideally you want the heq5. this is the cheapest new version http://www.firstlightoptics.com/skywatcher-mounts/skywatcher-heq5-syntrek.html if you add an eqdirect adaptor http://www.firstlightoptics.com/astronomy-cables-leads-accessories/hitecastro-eqdir-adapter.html download eqmod (freeware) and a laptop and you have a goto mount that is about the best entry level imaging mount you can get. add your camera some nice long lenses and you are away. then when you have saved a bit more get a 130pds and coma corrector or better still ed 80 and field flattener reducer to stick your camera on. then you can save a bit more for guide camera and bits after that its just more expense. Seriously though if astrophotograpy is what you want the mount is the all important bit and the heq5 is the best entry level imaging mount. You can do it on a cheaper mount eg the eq5 but it does not produce results as reliably, the last thing you need is to waste a rare clear night for imaging only to find that half of your subs are useless. Also recommended is this book http://www.firstlightoptics.com/books.html
  14. go by the worst forecast its usually most accurate
  15. yes it works for visual its not great for photography though
  16. Sir I beg to differ speeds over 8mph are certainly injurious to health. Why only recently I was hospitalised whilst only travelling at 9mph in a tightly bound polythene sack and again whilst stationary in a locked fridge freezer it is quite possible I would have died had the fridge been moving.
  17. the synscan eq5 motors will fit the vixen gp http://www.firstlightoptics.com/skywatcher-mounts/synscan-pro-goto-version-3-upgrade-kit-for-eq5.html for that price you won't get a better mount although a 2nd hand heq5 comes at about 500 and will be better
  18. I have recently switched back from an 80mm apo to a 5"sct as I missed the apparture I use a reducer in my c5 which brightens up the dso's though it doesn't give me the wide views of the 80. i use home made setting circles on my tecnosky mount which will at least get me close enough to find things and with the reducer and a 70 degree eyepiece it doen't feel like looking through a straw. the reducer definitely makes a difference on a small sc tI hear it doesnt have the same effect on the bigger ones.
  19. f6 is well within the tolerance of most decent eyepieces. As to the merits of the es ed80 I wouldn't know for sure only guess. what makes the synta unit so good is its colour correction. How it achieves this is by having a slightly longer focal length. most of the ed80's I have read about which have shorter focal lengths have problems bringing the blue channel to focus causing bloating when imaging. i hear this can be processed out but it still doesn't appear to be something that's wanted. I am sure that the es ed80 is the same unit as the altair starwave
  20. I was looking for some help on stripping down my vixen super polaris and i came across a thread on SGl http://stargazerslounge.com/topic/162745-lubricating-old-vixen-polaris-mount/ This thread mentions a gentleman called Carsten Arnholme who has published online such a stripdown. Unfortunately I cannot find the url and google doesn't appear to want to be my friend so if anybody knows the url or has downloaded an offline copy I would be grateful for the information or even any more clues to the mysterious carsten Arnholme
  21. 2nd hand is a good idea if you know what you are doing but don't forget to do the research before buying on ebay. Not all of their scopes are a bargain and not all of their scopes are very good if you are not sure come back on here and ask. 2nd hand prices are generally 50 -66% of new unless the item is particularly sought after ie rare then you are talking about 80% +
