  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
  16. Hi, I have just spotted this on the BBC News Website: BBC News - Venus and Jupiter to pass in the night sky Hopefully that will get a few people out this evening looking up at the sky. And at least Venus and Jupiter are so bright that they can be seen in the most light-polluted skies.... Jim
  17. Hi DC, I had a first look at Venus earlier last month through my 150P, and yes - I wasn't disappointed either! As you say, I could quite clearly see that there was a "phase" to the disk - somewhat less than a "full Venus" as it were, but more than "half-Venus". And the light seemed to be a bluey-green. All together a lot more interesting than I had been led to believe...! Best Wishes, Jim
  18. Hi, I've just used these instructions/photos to help me install a synscan upgrade on my newly purchased (secondhand) EQ5 - worked perfectly! Thanks so much!! Jim
  19. Thanks James, Looks like I shouldn't be waiting too much longer, although I have been told that it can take up to several weeks to get USPS shipments over here and delivered.... Jim
  20. Hello there, Sorry for hijacking the thread, but I've ordered the 7mm from this supplier, and I'm wondering how long it took yours to arrive? Best Wishes, Jim
  21. Thanks Peter, That's really useful to know! Regards, Jim
  22. Hi, Can anyone tell me if there's any difference between these two handsets in terms of operation? Can a Celestron Handset be used to drive the motors for an EQ5 Synscan system? Clear Skies! Jim
  23. Hello Lee, I do seem to remember picking up a couple of accessories (including a red dot finder) for cheaper than normal retail price a couple of years ago. I'm going to be there again this year on Friday week, attending the first conference session with my daughter, and I was also going to take a look at the exhibition to see if I can spot the odd bargain to cross off my shopping list! Jim
  24. Signed and shared on FB. Thanks for the heads-up! Jim
  25. Hi, I thought I should just give a mention to Optical Vision Ltd. I have a Skywatcher 150P with the 1.25/2" crayford (single speed) focusser. There are rubber grips on the focusser wheels, and one of mine had split into two, falling of the wheel. I had serached in vain to see if any online retailer supplies spare parts for Skywatcher telescopes (as opposed to accesories), so I sent Optical Vision Ltd an email, using the "contact us" function on their website, asking them if there was a retailer who could supply a replacement. I got an email back stating that they had popped a couple in the post, first class, and they should be with me shortly - no charge. They arrived the next day and one is now fitted - the other will act as a spare. Great service! I shall no doubt pop along to their stall at the Astrofest exhibition to thank them personally...! Jim
