  1. Thanks bryand and Ruud, I have just been looking on line and I just had no idea that there were so many books available in this particular field of observing .....a case of being spoilt for choice I think.
  2. Very positive replies, thanks HollyHound ......think I'll put the book on" wants" list. Sounds an interesting and popular volume just to have in one's kit.
  3. Thanks for reply, Tomatobro, No, not interested in photos of objects but otherwise very helpful and particularly regarding use of finders, telescopes and binoculars. I don't use Stellarium though.......not yet !.
  4. My main bino observing guide is James O'meara;s book "Observing Night Sky with Binoculars" Excellent it is , although I do find his information on celestial mythology a trifle distracting. The book also supports the use of a small telescope which I use sometimes. I am not at all familiar with the contents of "Turn Left at Orion" but note that the the original publication was intended for the small scope user and which is still available via the 2nd hand book trade. I have read such a lot of high praise about this book that I wondered if it would be of any benefit to me. If anyo
  5. Ricochet, I wasn't aware that Celestron had introduced a new design finder for the Astromasters....... I have been looking at the adverts and the finder looks greatly improved no doubt influenced by the poor response to the previous one........the one I have . I won't refit it to the scope but will probably hang on to it for the time being. Crossway.
  6. Cosmic Geoff, Unfortunately I cannot illustrate the finder with a pic but Steve's link 3 posts up is the one in question. Must say the news so far is not very encouraging is it !!! Crossway
  7. Yes Steve, that's the one and note that you are familiar with it from years back.......did you ever have any success with it at all?. My 76 AZ is mainly used on short range terrestrial stuff like sea birds and ships but when required I use it with a small finder scope and right angled eyepiece. The small Celestron red spot finder was obviously designed to work and I'm therefore reluctant to dump it in case it is my technique which is at fault.
  8. Thank you for replying Ricochet.......my query was unfortunately not explained all that well and I apologise for perhaps wasting your time. The Celestron "Astromaster 76" has a very small red dot finder tacked on to a permanent mounting at the very end of the tube just above the spider . The initial exercise of aligning scope and finder using a terrestrial feature I always found to be hit or miss and subsequent aiming of the scope onto the intended target was inaccurate. I think that the problem with the finder is something to do with its small size and the
  9. I have a Celestron 76mm newtonian which I intend giving to my grandson ,........It was used mainly for bird and ship spotting at the coast and I imagine it would continue to be used likewise. Despite a somewhat flimsy tripod the scope works very well but I am a bit dubious about re- attaching the small red dot finder which I could never get the hang of. Could I ask if anyone has any experience of this gadget as a useful aid. Thanks. Crossway
  10. I think it might have been 10 or more years ago when I was invited to attend a lecture at the University of Newcastle 's observatory which was then located at Close House , Wylam Northumberland. They had a large reflecting telescope . perhaps of the order of 14 imches or more which they were proud to show to us visitors. The mirror, I thought, was very grubby indeed and I mentioned this to our host who told me that the performance of the mirror was not un duly affected by this and that they would only clean it as a last resort..........he didn't explain where this last resort lay.
  11. Just curious really, but is there any real significant difference between observations using a Skywatcher reflector and a Celestron of the same size. A dealers catalogue of Skywatcher scopes invariably states that the primary mirrors are parabolic. The technical descriptions of the Celestron scopes does not mention this..........although it may well be a fact. I have to say that my own use and regard for my Celestron is without any criticism at all. Pete
  12. Very pleased to have got my new home made ex bino optics ) finder scope up and running with great success. I fitted crosshairs in the eye piece using fibre optic filament which, when magnified gives a somewhat "vigorous" image but absolutely ideal for its purpose.. I had also done some experimenting with putting cross hairs in a 20mm eyepiece to assist in aligning the main and finder scopes but as I proved to myself this is not at all necessary and a waste of time. The alignment is carried out in daylight anyway ....in my case via a very distant tree on the horizon and centring the ima
  13. My post this a.m about this calamity was curtailed prematurely by a domestic arrangement to do with shopping!!! Having made sure that my scope had suffered no exterior damage I set it all up again and checked the optics and was astonished to find that the collimation was absolutely intact. My finder scope was pointing somewhere else but soon got it back on line. So the system is OK again. I am sorry to hear that other stargazers have had some hairy moments as well ......its a nasty jolt. I have now had time to examine the dovetail assembly and although the Celest
  14. I had my scope out last night setting up a new finder which I had just made and relishing the seemingly once in a while really decent clear skies. I had just targeted into the Hyades which were at a moderately high altitude when my scope ( a reflector ) slid out of the dove tail and crashed down onto a hard paved surface. The noise of the crash was awful and it was a while before I dared pick it up and didn't know what to expect in the way of damage ........at the least some misalignment of optics or worse, a cracked primary.. But how very very fortunate to find that the only
  15. Helpful replies and thanks everyone. Will enjoy getting started on my next project and have taken serious note of warnings about treatment and care of these filters. There was a thread in SGL just a few days ago about the on going absence of clear night skies .........here in the North East it seems to be permanent . Murky days are in high figures as well so hopefully a new sun filter will attract some good luck!! Pete
