  1. Hello Baz, Sorry for the delay in replying, I've been away for part of this week for work, so I've only just seen your message. You're welcome to them. I did have one other guy from SGL express an interest, but only in one particular issue and the free software on the CD, and I didn't want to split the collection. He may contact you asking if he can have or borrow that CD from you. Anyway, I'll check the cost of postage - you appear to live in Rossendale, which I seem to remember is up in Lancashire, but if you wish you can send me a Private Message with your address. We can then sort it out. Thanks, Jim
  2. Hi, I have a set of Sky at Night Magazines that I got some years ago, ploughed through and would now like to pass on to someone in the group. It is a complete set of Issues from number 1 in June 2005 to issue 72 in May 2011 and comes with all the CD-ROMs that were attached to the front. Happy to send for the price of postage/packaging (quite heavy!), or they can be collected from SW18 in SW London. Anyone interested, please let me know! Jim
  3. Hi, I bought LX eyepieces so I guess I'm in that camp...! They seem to work very well in my F5 Scope. I saw your ad in Uk Astro B&S and thought it was an interesting choice to make..... But it seems that you are not the only one switching to the LX!! Regards, Jim
  4. Hi, I have no experience of this scope, however I did have a quick look at the instruction manual you linked to, and was thinking about the best way forward for you. The first thing to say is that it is not at all obvious from the manual whether the primary mirror is parabolic or not. This will have quite a significant effect on whether it is worth perservering with the scope. Secondly, what diameter are the eyepieces and barlow? Are they the currently most common 1.25" or are they the much less common (nowadays) 0.965"? If they are 1.25" then you can always begin to purchase some more decent eyepieces and a decent barlow to try out on your scope, knowing that if you do decide later to upgrade to a better scope then the eyepieces will still be useful to you. However, if your current eyepieces/barlow are the old 0.965" then that option won't be there. Thirdly, you might chose also to upgrade the mount/tripod. If you decide that the scope is worth it, and you get much better seeing through better eyepieces, then it may well be worth considering getting a more sturdy mount/tripod combination. I hope this helps! Jim
  5. Hi, I had a set of these until recently when I upgraded to X-Cel LX eyepieces instead. I have to say that for the price they were very nice in my f5 SW 150P reflector. Only fault I found was with kidney-bean shadows on a few occasions - not entirely sure why... Jim
  6. You're welcome! That's what this forum is all about! Clear Skies, Jim
  7. Hello Algie42, I've got the Maplins version that you linked to in your message above - it works fine. Looking at the Halfords one, it seems to be the same spec (up to 5 Amps at 12V) so will also work fine to cope with the maxmium 2A that the Synscan draws. Although the Maplins is normally £24.99, they currently have a deal on, selling it for £14.99, so I'd go for that one if you have the choice! Best Wishes, Jim
  8. Hi, I know this thread is supposed to be moved, but I thought I'd just reply to state that I think you are supposed to use CTRL +1 to move to the cross-hairs, not ALT +1. Best Wishes, Jim
  9. I agree totally with that dobbie - well said! Jim
  10. I agree, and have now got the 7,12,18 and 25mm with my scope, together with a Celestron Ultima 2x Barlow. Very happy with the views I'm getting! Clear Skies! Jim
  11. Hi Malc, These two articles may help: Starizona's Telescope Basics Magnification They are both based on rules of thumb at around 50-60x the diameter of your scope in inches - e.g. 6" reflector -> 300 - 360x max mag. If you do a search on the internet there are more in-depth articles that give the physical concepts as to why these rules of thumb hold. But also remember - they are absolute max mags in perfect seeing conditions! Clear Skies! Jim
  12. Hi, Adding my tuppenceworth, when getting down to such short focal-length / high mag eyepieces, when using the 150P/Eq3-2 combination, I found the biggest problem to seeing was the time it took vibrations to settle down - any slight touch of the focusser or eyepiece led to big shakes in the FOV for several seconds! I agree with what's been written already - 150 - 200x should perhaps be what your routinely aiming at for max mag for your set-up. I guess that a 7 or 7.5mm with 2x barlow will give you magnification around the 200x mark which might be sensibly achieved. Clear Skies, Jim
  13. Hi, I seem to have found a clunky way of aborting CTRL + 1 type slew commands in Stellarium: Make sure that in the "Slew Telescope To" Menu you have the co-ordinates set to your park position (say) at Polaris and that your telescope is selected (as opposed to "virtual reticle"). Select the object you want to move to in the usual way. Press CTRL + 1 (or whatever your telescope is listed as). The telescope starts to move. If you think you are going to go past a limit of movement, hit CTRL + 0, and the "Slew Telescope to" window will appear. Now hit the "Slew" button and the telescope will immediately start to return to the co-ordinates you have set as Park position. See what I mean by clunky...?! May I suggest you try it without the telescope mounted a few times to see if it works for you? Good luck! Jim
  14. ....ah, I've just realised why my suggestion is so silly! You're problem is when you're using Stellarium to move the mount to an object, not when tracking it, hence your rush to hit the power button (on the Synscan motor controller) if it gets close to a "limit" - i.e. risk of collision. In that case, unless you have been told anything different, I can't think of a command in Stellarium that stops the goto completing its move.... Jim
  15. Hello Mike, Did you ever get an answer to this question? I have just installed a synscan upgrade on my EQ5, and I am intending to try out Stellarium to control the mount. It may be a very silly suggestion, but would hitting the "Pause" button in (the latest version of) Stellarium stop the slewing? Best Wishes, Jim
