  1. You would see the same magnification but the border of the image will be cropped off.
  2. A 35mm lens is always a 35mm lens. If you put it on a crop sensor canon camera it would give you a smaller field of view. It would not be any more/less zoomed so you would call it 35mm whatever camera you have it on.
  3. Would I not lose the magnification from the eye piece then? When I used it mounted on the low quality 2x Barlow the image I saw of Jupiter was tiny. Mounted directly on the scope I assume it would be even smaller still. Would it not be pixelated to hell by the time it was blown up to a size with any detail?
  4. Does a 127 mak scope have a much greater degree of magnification than a 130p using the same eyepieces? If so... How much more?
  5. I had a look at Venus last night at 10mm on my 130p. 650mm length. Not sure what mag that is. I could make out the crescent on one side. I'm trying to get hold of a filter to cut down the glare. Also I had my best view of Jupiter so far at around 18:00. 4 moons all spread out on one side. Fantastic. I want better EPs now.
  6. I'm think I'm going to have to be swayed by the camera mount issue. I can't mount my Eos600D directly on the scope as it doesn't focus. It does with a barlow but with my cheap barlow the image was horrendous.
  7. more of a lens distortion then... stretching towards the edges
  8. can you mount a camera on them? and could you possibly just explain edge correction? Is that how blurred you get the further from centre of the field of view? Or like chromatic aberration? (which i understand)
  9. Just another quick question.. First Light Optics - Cheshire Collimating Eyepiece Is this the ONLY thing need to collimate my scope? About time I learned how really.
  10. I'm going to order a 24mm and (probably) an 8mm tonight. Pretty much replacing what I have with better. Looks like stocks on filters are drained so will investigate more on that front later. Let me know how you get on with yours Malcspring.
  11. Had my first look at mars the other night and wondered what kind of magnification you would need to see it with any detail.
  12. I've got the same eyepiece set with my skywatcher 130p. The Barlow is the worst piece in the kit. It turns any view into to blurred mush. I would advise trying to manage without it.
  13. I want to upgrade the stock eyepieces (10mm, 25mm and 2x) on my Skywatcher 130p which if I have worked it out correctly 650/130=f5. Going by the sticky 'which eyepieces thread' a suggested kit would comprise of 2x Barlow, 8, 18, and 25mm. Ive been looking at the Hyperion Zoom for quite a while but was weighing it up against the fixed focal length Hyperions. Is there much difference in image quality? From I gather you can take some of them apart and with a fine tuning ring it will give you different focal lengths. Could somebody please explain which eyepiece I would buy to get the best benefit from this? Is the fine tuning ring option worth forgetting about and going with the celestron Eps? Are they as good? I need a barlow too because the one I have just seems to badly degrade the image. Is the one that matches this set any good? I'm happy to fork out the cash but I want to make sure I spend it properly. I also want a filter that will give me less glare viewing planets, moon and nebulae. Is there a one stop shop filter for this purpose? I know I'm asking quite a few different things here but your collective expertise would be much appreciated. Many thanks in advance.
  14. yup. edit:... no. face palm moment. thanks for that.
  15. I went outside to try to have a quick setup with my synscan goto 130p. I know the batteries are low so i wanted to do a quick 2 star align. Its been a while since I have not used it over xmas and i usually use it in the back garden and tonight i was going to use it out the front of the house so it was going to be different stars to usual. I was surprised and annoyed to find that none of the brightest stars that i could see clearly were in the list to choose from. No Aldebaran, no Betelgeuse, no Mirach. Sheat was in the list but out of my line of sight. Should I expect those starts to be in the list? Can I update it? Also.. what kind of filter could i use to make Jupiter a bit less bright and more contrasty? Im just using the stock eyepieces that came with it at the moment. one of these? http://www.firstlightoptics.com/light-pollution-reduction/baader-neodymium-filter.html I was thinking of getting one of the baader hyperion zoom eyepieces. Anybody have any experience with them?
  16. I have a skywatcher synscan goto 130p. I live in Peterborough and the only thing I've got much joy from is looking at planets. Dso is a no go with the light pollution. If I was buying a scope for the first time knowing what I know now I would have dumped the fancy stand and got a 8-10" dob and some nice eyepieces.
  17. The subject of Melvyn Braggs show today is neutrinos.
  18. The well known ones are all included in solar walk. Zooming in on Jupiter to see its moons orbiting around it is very cool indeed.
  19. Most sodium streetlamps will be either a 70w or 150w lamp. I do not have any idea what rate your local council will be charged for the electricity they use per hour.
  20. Will most dslr cameras happily plug into the software in a 'webcam' type arrangement then? I know my current compact doesn't. I'll be a bit of a fool if I buy the 550d to find it doesn't. I'm not sure what you call that kind if functionality in the tech specs list though.
  21. Well I'd planned to have a drive out and about around Marholm way on Friday but it wasn't very clear so I never bothered. Weather had been rubbish since then so scope has just been stood unused in the spare bedroom.
