    Welcome to SGL - as it happens - today I bought thermal socks and a thermal bobble hat - even now it gets really cold by midnight (so much for those supposed warm summer nights...)
  2. The Telrads brilliant though - I do all my star-aligning with this to set up the GoTo (you have to then fine tune the align in the scope of course) - its really easy with the Telrad though, and the matches are always spot-on. The ability to increase & decrease the brightness of the concentric sighting circles is also a big plus - for fainter start it is in fact critical, and really does enable much faster and more accurate star hopping. It is fairly big (but very light), but no bigger than a normal finderscope size.
  3. When I was scanning all of the reviews a few months ago the Skymax 127 was consistently coming out very well. I can also add tha the GoTo is a great feature for a beginner - you can always turn it off as well to get more star-hop experience

    HELLO :D

    Welcome to SGL from me too...
  5. Welcome to SGL - it's a great site
  6. Hello to SGL, from a not-so-sunny Devon at the moment
  7. Welcome from me too - enjoy!
  8. John - why do you say the 4mm TMB is no good for your SCT? Is it too powerful?
  9. Astronomica (http://www.astronomica.co.uk/) also stock these - several suppliers as i have found today are out of stock, so there is clearly a new demand for these. Astronomica confirmed to me today that they have stock of the TMB 6mm planetary eyepiece.
  10. thanks I'll try this - I've just noticed you have some great screen shots from Stellarium on your weblink
  11. can you reverse the colours though? In other words, can you switch the black (virtually all of the background) from the red stars? Otherwise this will be mighty expensive on the printer ink!
  12. I use Stellarium and it's great - however, sometimes I just want to focus on an area of the sky and go into the details - here I would really like to be able to print out the Stellarium image and have it by my scope to refer to rather than always having to boot up and use my laptop outside. However - so far I have not found any way to print the actual image that you see in Stellarium - has anybody managed to do this?
  13. I have an 8" SCT Celestron CPC800, and am looking to upgrade to a high quality planetary eyepiece - Jupiter is waiting! I gather that my CPC800 (2032mm focal length) will take at best a 5mm EP for best magnification without distortion. I've been looking at the Televue Radian 5mm and the Televue Nagler 5mm EPs - both come highly recommended. So my question is what are the main differences and the pros/cons of each. I gather that the Radian EP gives very good eye relief, and is claimed to be very good for observers with spectacles - but this is not relevant to me. Both eyepieces come in somewhere between £170-£200 - which is pricey, but I assume I'll appreciate the extra detail they will offer on my CPC800 - tell me though if this is a mis-assumption. The other option I have is to buy a Meade Plossl 5mm EP or similar which comes in at a third the price (£63) - tell me is there a major real positive benefit by having either of the Televue EP's above and will I really see a significant difference versus the cheaper Meade EP? Thanks for your help
  14. Hi there, and welcome. I also went to the NLO open day a few weeks back, and subsequently joined their Society. I live near Cullompton so this is actually the nearest Society for me (I'm also a relative beginner, so have lots to learn).
  15. Welcome - I also started earlier this year with binos, and then 3 months later bought my scope. Even now though, I can still spend half the evening with the binos rather than the scope as I'm still learning al of the constellations, and where the Messiers and Nebula are in relation. It's really satisfying to be able to know most of the bright stars and star hop and find M31 and M13 etc. I'm in Devon by the way, near Cullompton.
  16. Hi Paul, I bought a pair of Canon 10 X 30 image stabilizer bionoculars. They are not cheap, but the image quality is spectacular. When you have to hold normal binos to the sky for any period of time, focussing almost to infinity, even the slightest movement makes for shaky images. The Canon binos eliminate virtually all of the shakes, it's remarkable - you just press the button, and the image magically smoothes out and presents fanastic images, which are comfortable to view for long periods. You can scan the sky as normal in stabilized mode as well. Without the shaky image, the details really comes out much more, and I can actually see more (and for more relaxed time) than I can with my previous binos (Celestron 10 x 50). I highly recommend these Canon binos. Martin
  17. I use Stellarium on my PC to orientate the night sky, and for star hopping - in this software package all the stars are given HIP numbers. However, my Celestron uses Nexstar which wants an SAO number entered to find a star. So at the moment, other than for the more common/brightest stars (which are listed under Nexstar), I cannot instruct guide my telescope to go to other stars that I find on Stellarium since I don't know how to convert a HIP star number to an SAO star number. Does anybody know how do do this? Thanks, Martin
  18. Hello - I'm a new member to this site, and recently bought my first telescope (Celestron CPC800). If there's any other member that live locally around the Cullompton/Exeter/Honiton area in Devon - it would be nice to connect. Regards, Martin
