  1. Thanks, all. I guess I'll just bide my time and wait for one of those No.120 buses to come along.
  2. To all those still following this topic and have recommended the ED120 are we all agreed this would be the best buy for refractor visiual, please? http://www.skywatcher.com/product/bk-120ed-otaw/ There seems to be little point in spending £600 on something that I will find ultimately lacking if by squeezing the plastic a bit harder, or putting off the purchase either until something second hand turns up (or after a couple of extra months hard saving) I can relax about the, (rather considerable), extra expense of buying new and know I've got something for life. Consensus seems to centre on this 'scope. Thanks to all who have taken the trouble to reply.
  3. Thanks, Olly. I shall be taking my time and searching the small ads but I just feel that before my eyes go completely, my grey matter turns to irredeemable sponge and the pension fund collapses under the strain I should spend some time with a refractor of some kind. I got the 150p-ds, used, as a gift and I haven't had a chance to take it outside in southern England yet but it will be spending the summer months in France so I hope to do have a go at some imaging then.

  4. That's the kind of informed comment I have come to expect from SGL and it is pertinent. At one point last autumn I left the tube of the Dob open in the barn and next time I went to use it, some weeks later, found dead spiders and all sorts littered over the main mirror. After stripping it down, cleaning and reassembling I carried out what was probably the most thorough collimation the Dob had ever been treated to. Then the weather hit and we went for weeks without clear skies and the planets, on those odd occasions when they might have been seen, had gone some place else. My highest magnification EP was 5mm, which was probably a step too far. I was advised early on that 6mm was probably the most likely to give the best result. I have now invested in a 6mm. However, most of my gear is in France and I'm in England until 28th March, so I have to wait until then before I can see what difference this makes. If the improved collimation, correct eyepiece, helpful juxtaposition of planets, clear skies do indeed let me see what I want to see with the Dob then maybe an 80mm APO will be enough of a refractor. Thanks for the observation.
  5. Thanks to everyone, I have truly appreciated all the advice here and will seize whatever opportunity presents itself first in the light of that advice, with practical, affordable quality as the guiding principle.
  6. Well, I've taken a look at the pictures - which were superb - but I've also checked user reviews submitted by, predominantly, experienced astronomers in the USA. Without exception they all comment on the astonishing lack of CA. I've not been able to trace pictures taken by any other users but all the reviews were from people impressed by the quality of visual observation. CA seems to be noticeable with Jupiter but not much else unless you spend more time looking for the CA than at the object itself. Though it is more expensive than the Bresser Messier 127s/760 it looks as if it could be money well spent. Thank you.
  7. Thanks, Paul. I'll keep a look out. I'm not in a hurry.
  8. Thanks for that. I'll take a look at the pictures. It's certainly a more affordable solution.
  9. Is this the one you chaps were recommending? https://www.firstlightoptics.com/equinox/skywatcher-equinox-120-apo-pro-ota.html If so I gulped, swallowed hard and reached for the tranquilisers. Way out of my price range, I'm afraid. But thanks for even thinking I could run to it.
  10. Thanks, Paul. I will check out the ED120
  11. Thanks, Dave, This is the one I had in mind http://www.bresser.de/en/Astronomy/Bresser-Messier-AR-152S-760-Hexafoc-Optical-Tube.html Bresser sell this mounted on their strongest own brand mount which is less sturdy than the AVX, I believe. There is a 5" short tube version and each can come with longer tubes. I have not seen a bad review of any from this brand, which may be based on earlier ES models. Apart from the optics the focuser seems ideal for 2" EPs and there are other fringe benefits (and I don't mean chromatic!). Peter
  12. Thanks, Peter, For AP it would seem that the 6" SW 150p-ds I have already will take me to the limit of any ambitions I might have in that field. It is on a weaker mount at present so should benefit from the AVX. Having read so much about the observation quality of a refractor being so much brighter, crisper, revealing and generally superior to reflected observations it seemed the way to go. Even with my 8" Dob under clear French skies I have yet to see the GRS on Jupiter, the snow caps on Mars or a clear view of the Cassini division of Saturn. If I am mistaken in expecting better observing then perhaps I'll save the money; otherwise I should maybe amend my enquiry to concentrate on the best value for observing only with an achro.
  13. I've just taken advantage of FLO's sale price on a Celestron AVX mount which I can use with a couple of tubes I have already, 6" Newt and 4" Mak, but I would really like to get hold of a refractor at an affordable price (Achro - obviously) which will give me good observing with reasonable AP opportunities. There are a couple in the Bresser Messier range, which have had good reviews, but not much user input. There may be others. If anyone has any sensible suggestions I'd love to hear them. Thanks as always.
  14. As a result of a thread I started just a few days ago I bought a 17Ah Phaze 4 in 1 jump starter from Halfords for £40 on the advice of a member who told me the battery in the case is the same as that in the Celestron/Skywatcher. The Phaze has two cigar lighter outlets and even has a USB port for charging things like your mobile 'phone if suitable. From the responses I got it seems you would be paying about £100 just for the SkyWatcher sticker on the side of their branded 17Ah. The chap I bought my EQ£-2 Synscan from demonstrated it's functionality before I handed over the cash by powering up from a similar, clearly well-used, jump start battery. I'm sure other members will respond in a similar vein.
  15. Thanks for the tip, Geoff, but I've just picked one up from my local Halfords. After a recent eye operation I'm stuck in England until I get the all-clear, probably late March. So if we do get a clear sky in southern England some time in the next 30-40 days I'm off chocks and ready to go. In passing, I needed a couple of M4 bolts to attach a new red dot finder. Homebase is closest. Forget it. Pre-packaged items with a choice of about 12 different roofing bolts. Toolstation or Screwfix would sell me a packet or box if I knew what size I wanted. I got what I wanted in an old-fashioned hardware store in Horsham for 40p. Any French DIY shop stocks an extraordinarily wide range of screws, nuts, bolts, washers which you can mix and match and buy by the maximum you can cram into a given size plastic bag at a fixed price per bag so if you are not sure of the size you can try before you buy or suck it and see when you get home with the selection you picked. Their economy may be in ruins, their politics are mystifying and the cost of the civil service is eye-watering but sometimes the French do get it right.
