  1. All I can say is...good luck! Which university is it?
  2. Use Microsoft WorldWide Telescope. Google Earth, well GoogleSky is really quite bad, the images are very crude and I would rate MS WWT higher. Not only can you get clear images of the planets but the program also allows you to select a wide variety of telescope and satellites to view the universe in a range of wavelengths.
  3. Hey kids, I came across the Taiwanese company GSO (Guan Sheng Optical -think thats how they are spelt) yesterday and have read a few comments on thier optical quality being better than the more mass produced Chinese optics of other rival brands. However the main thing is, I have never heard of this company before and also that they do not seem to ship to the UK. I had to visit an Aussie site to get any info. Their own website gs-telescope.com appears okay from the front page but has major flaws in the rest of the layout, namely product information. Was wondering if anyone had come across this company before and has any views on them ? From what I gather their products are lower in price than other rival manufacturers (which is good) and slightly higher in quality (which is better).
  4. I have used it, I haven't used the telescope feature though, but the program itself looks good and is far better than Google Sky, which in my opinion is crud. I would defo. recommend this piece of software
  5. I would use lat/long but its a general accuracy, so I assume london will be okay. Obviously there are discrepancies when doing even the most accurate alignment. After you have chosen, date, time and site do a thorough 3 star alignment or wedge align followed by a manual 2 star E north alignment, I found this the best for my NexStar 4SE
  6. Stellarium ain't that good, fair enough it looks the part, but content wise and versatility its poor, it also slows you computer right down. I would use Voyager 3 /4 by Carina Software or Cartes Du Ciel...far better programs.
  7. Brilliant image, I would recommend this for Picture Of The Week.
  8. I agree with 'Jahmanson' on the dobsonian point...... Kids want fun and simplicity (having been one myself), I would keep it easy for now and let your nephew grow into it if he wants to. The good thing about a dob. is the aperture, manouverability and range of observations it can handle. The Nexstar 4 is a mak. cassegrain and for DSO's like faint nebulae and galaxies it doesn't portray them as brightly or as clearly as a newtonian reflector. That said, the mak. does give good contrast for planetary observations although I guess that when you show a child (or indeed anyone) Saturn or Jupiter they want to see the rings and cloud bands, the NexStar4 isn't too good on that point as the cloud bands on Jupiter are not visible and it appears as a large orange blob. The refelector however can distinguish the bands and rings quite well thus giving a better 'wow' factor, I would try for a cheap 5/6inch reflector and maybe get a barlow lens aswell......thas my input.
  9. Reply to 'Mik', The Nexstar 4 DOES have the wedge feature. The forks for the 4 & 5 are the same whereas for the 6 & 8 the fork is slightly larger. I can't understand how Celestron made this mount out of plastic it is so prone to vibration. For a grab and go scope the 4 is okay but there are others out there which are more appropriate
  10. No worries! I shall probably end up getting a proper EQ mount, but was wondering if it was at all feasible to make a dob EQ mounted and motorised
  11. Hee hee, What I meant was without using an EQ mount such as an EQ-5 or EQ-6, I mean, can I create somekind of DIY wedge that would be relitively cheaper that lashing out £400+ on a EQ mount.....
  12. Hey kids, Wondering if it is 'easy' (money and effort wise) to make a Celestron Starhopper 8 inch setup Equatorially mounted and then allow it to be motorised? If it is, what equipment would I need? Not particularly thinking about having goto or anything like that, a simple sidereal motor to track the sky is all I am really after as I can find most things myself. Cheers
  13. great image, lots of detail, was it a guided image? there is virtually no trailing on your stars!
  14. Hee hee, Thanks guys....... have a 12v power tank but were off away on a mini-holiday next week and she's taking her scope but she has never used it with a battery in before (women eh!) Some other people might have a powertank to use, thanks though
  15. Hey kids, My friend has a HEQ-5 non pro scope and she doens't know what battery to get to power it. Not after a power tank only a battery, so what does it take?
  16. Favourite dso observed = M27 the Dumbell Nebula Favourite planet observed = Jupiter Favourite dso image = Rho Ophiuchus Favourite galaxy cluster image = Abell 2218
  17. Thats the beaty of clusters, you don't need to take long exposures so you can get away with your scope being unguided. Nice work!
  18. Your getting better at this, I shall soon be getting your set-up or thereabout!
  19. Blue Ranger, The scope sells for around £340, so with your £500 you can afford to get either a 2x or 3x barlow lens and perhaps some other eyepiece's. In my honest opinion and from using it just last week on Saturn then I can say that it is good enough for a beginner. I haven't tried the 4SE witha barlow lens, only the supplied 25mm EP. The image of saturn is quite small but you can make out the rings and possibly the cassini division but that may have been a distortion with my focusing. In my opinion Jupiter is a far better subject because it is so much larger and you can see the moons more clearly, that said though there are issues with veiwing the cloud bands on Jupiter, but with a barlow you should be able to make them out. Other views with things are good, M42 looks good, as does M45 etc etc, especially star clusters. The rather high focal ratio can dim down some fainter DSO's such as M51 and M101 and the FOV is a little narrow but you shouldn't be expecting lots through a 4 inch mak. anyway. In terms of use though, its far easier to set-up and use that a TAL 150. Its fairly small aswell so you can get it in the boot of your car no problem. If your wanting to try some basic imaging then perhaps get an EQ mounted scope, the 4SE does have the wedge but an EQ mount would be better suited....it all depends on your money situation and what you want.
  20. Going on what has been said + my knowledge, I would say that maybe you could look at getting the Celestron C6 or C8N-GT on the CG-5 mount and add a guide scope. Perhaps go for the 6 inch scope then the mount won't be pressured with the addition of the guide scope. It gives you the benefit of goto and a low price but there are some draw backs i.e. no polar scope, noisey mount, no directSLR camera connection and you'll need a powertank. That said you can get some cheap modded webcams / ccd's these days and I think you can even get a ccd which images and guides at the same time (might be wrong) so you may only need one scope. Like you said though, take your time and ask plenty of questions, don't jump straigh into it. It is far easier to get a basic scope and learn that first than thinking astrophotography is easy.
  21. As SteppenWolf quite rightly put, I would 'swerve' the SLT (by quite a wide margin) as it is not suitable for astro-imaging. You need an EQ mount for this. Given your budget of £300 to £800 I would perhaps go for either the Celestron C6/C8 N-GT, Skywatcher 200p or Skywatcher 150p on a HEQ-5 mount. The reason I put the C6/8 N-GT there is because although the mount is noisier than the HEQ-5 it is still sturdy and has the added bonus of Go-To. FLO is selling these for £515 and £595 respectively; http://firstlightoptics.com/products.php?cat=40 The Skywatchers are in my opinion on a better mount but given your budget perhaps a 150P on an EQ5 or HEQ-5 is your best bet; http://firstlightoptics.com/proddetail.php?prod=heq5 plus the 150P scope at £99 comes in at £479. The bonus with the skywatcher scopes is that they come with a dSLR connection and here an easter egg for you TESCO Direct are selling Canon 400D + Lens for £359 !! Bargain, for some stupid reason they are selling the 400D body only for £400, silly people!
  22. I would do what jgs001 says, use a powertank or like you have, a power cable. I think the problem with batteries lie across the entire SLT/NexStar range, its not that there isnt enough power from batteries its just that it gobbles it all up and I think that it distributes it randomly so it almost shorts out and loses what you tell it, theres no smooth flow of power (if that makes sense). I hated using batteries in my NexStar because you weren't sure if it would give up at a) turning it on aligning c) slewing or d) tracking, it was always a mystery and double-annoying when you get it aligned then it says 'alignment failed' grrr!!! Why they made it with a battery compartment that CLEARLY doesn't work properly is beyond me and thats coming from one of the top telescope firms in the world. Its like Aston Martin giving you a towbar thats made out of plastic a) you don't need it its useless and c) it's a waste of space Ooh, I am 1 post off 100 - go me!
  23. What are you on about....thats a quality lens! Ha ha, joke. I thought German's were good at making things!
  24. Is that lady a permanent fixture...if so, she ain't going to get much reception in space!
