From: TerryMoselaol.com Date: Sun, 7 Dec 2003 11:13:43 EST Subject: Lidl 'scope (2), Comet photos, Mercury Hi all, Some of you may already have got an earlier version of this - if so, apologies. But since trying the first transmission, I have been informed that it will be on sale in ROI from Monday at an unbelievable Б‚¬64.99! That's only about бё45.50.... So if you live close to the border, you know which way to go! (hope it's the same scope!) [Rest of original email follows] I'm now reliably informed that the Lidl 70mm telescope goes on sale on Monday. And it now comes complete with "Astronomy software and Star Navigator on CD". But the ad in Sunday Life does not mention the 'terrestrial' barlow, although it still may be included. BTW, the ad is a bit off-putting in that there's some weird translation, presumably from the German: it refers to the possibility of adding a "Specular refraction camera" to the telescope. Now that's a new one even to me...... And it also refers to the mount, not only as being an equatorial, which it is, but as "Sagittal". Again, that's new to me, unless it's a trade name. However, don't let that put you off, and anyway, the instructions that came with mine were clear & comprehensive. Three other points: it has a built in lens hood / dew shield; the tube is well baffled internally; and the focuser is nice & steady & smooth, and has plenty of travel. The optical tube assembly (w/o eyepiece) weighs only 1.1kg, so it's very light, even though it has a metal tube. The minum tube length is 700mm, but you could reduce that to 620mm by temporarily removing the focussing mount, so it would be quite easy to transport for anyone thinking of travelling abroad for the Transit of Venus in June. You could also easily make an adaptor to mount it on a camera tripod (I have already done so) if you didn't want to bring an equatorial mount. Over to you, folks. (No, I don't have shares in Lidl. And I'm risking the wrath of North Down Telescopes. Among others... But it's all for the benefit of you, the consumer!) BTW, they don't take credit cards! Just Debit cards, or cash, or a cheque & cheque card. Peter Paice, IAA member from South Belfast, known to many of you for his excellent solar photos, tells me that one of his comet photos may be on the Sky at Night tonight, as already notified (00.15, BBC1). Finally: fancy a challenge? See if you can spot Mercury in binoculars this afternoon. At 16.30 it will lie 7 degrees 20 mts below & right (about 4.0 on a clock face) of Venus, at an altitude of 2 deg 40m (just over 5 moon diameters) low in the Southwest. It will be mag -0.4, which is quite bright, though nowhere near as bright as Venus. That separation is just a bit more than the field of view of average binoculars, so you'll have to sweep just a bit below & right from Venus. DON'T look while the Sun is still above the horizon! That altitude refers to Glengormley, at that time. The further South & West you are from here, the higher Mercury will be at that time, and, of course the further West you are, the later sunset occurs, so wait a bit longer to look for it - say about 16.40 for Galway or Limerick. But you'll need a very clear sky right down to the SSW - SW horizon. If you are still out at about 17.30, look out for the ISS coming over for a reasonable pass (about 17.35 for Belfast). There's an even better one tomorrow evening at about 16.30, though that's in brighter twilight; if you don't see Mercury this evening, try for it again tomorrow, AND get the ISS at the same time! Mercury will be fractionally higher & closer to Venus, at the same time tomorrow evening. Good luck. Clear skies, Terry Moseley
