Charlie_132 Posted July 16, 2012 Share Posted July 16, 2012 hello, ive got a skywatcher heritage 130p telescope and going to try to find neptune on the next clear night, will i be able to find it or isnt my telescope powerful enough ? Link to comment Share on other sites More sharing options...
DirkSteele Posted July 16, 2012 Share Posted July 16, 2012 Neptune is approximately 8th magnitude. Well within range of your telescope, though given its small angular size (only around 2.4 arc seconds) you will need pretty high magnification for it not to look stellar. And it will never more than a small bluish disc.Clear skes, Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted July 16, 2012 Share Posted July 16, 2012 You should be able to spot Neptune with a 130mm scope, but even in my 8" it is a barely resolved disc. The blue-green colour is the most striking feature.Happy hunting! Link to comment Share on other sites More sharing options...
Charlie_132 Posted July 16, 2012 Author Share Posted July 16, 2012 i ll have a look in the next week whenever its a clear nightwould i be able to see it with a 2x barlow aswel or would that be too hard ? Link to comment Share on other sites More sharing options...
JamesF Posted July 16, 2012 Share Posted July 16, 2012 My experience is the same with a similar size scope. You can see it, but with a small scope you may struggle to get enough magnification to spot it amongst the background stars. When I first found it I was only sure it was Neptune because it was where Stellarium said it should be and there were no other objects of a suitable brightness. It's nice to find and really challenges your star-hopping skills, but it's not an incredibly rewarding target otherwise Jmaes Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted July 16, 2012 Share Posted July 16, 2012 I used 230x and 290x when I last spotted Neptune (years back). In your scope I would not go beyond 200-250x, whether you do that using short focal length EPs or with a barlow is immaterial. The main issue is to get a good finder chart for Neptune (try Stellarium, which allows you to make charts of what the star field should look like in your telescope, with your EPs).

NGC 1502 Posted July 16, 2012 Share Posted July 16, 2012 Hi, as others have said, your scope is capable of showing Neptune. To definitely confirm you have found it, if it resolves into a tiny bluish disc at high mag, or better still, do a very careful drawing of the star field and what you think is Neptune, and do another drawing the next night or as soon as you can (yes I know the weather makes that difficult at the mo ) but it can be done, and Neptune will have moved relative to the background stars.I did that many years ago to find Uranus with my 4.5" reflector, it's actually quite a buzz to find these outer planets.Regards, Ed.

faulksy Posted July 16, 2012 Share Posted July 16, 2012 i have seen it and as said you will need high power and then you will see the lovely blue tone like pastal shade Link to comment Share on other sites More sharing options...

magic612 Posted July 16, 2012 Share Posted July 16, 2012 I did a star hop to this in my video from last week, which should make it easier for you to locate. Hope that helps. Link to comment Share on other sites More sharing options...
paul schofield Posted July 16, 2012 Share Posted July 16, 2012 I would be very interested to know how you get on. I have never tried to see Neptune or Uranus due to thinking they would be really small. As NGC1502 says it must be a real buzz to see them, especially when you consider the distances. Good luck and let us know. Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted July 16, 2012 Share Posted July 16, 2012 I remember when I first spotted Uranus and Neptune on the same evening (1996, I think). The solar system seemed to become a bit bigger for me. Link to comment Share on other sites More sharing options...
swamp thing Posted July 16, 2012 Share Posted July 16, 2012 Neptune has always been my favourite planet, it's a great challenge. First off finding he little fella then trying to resolve the disc.It doesn't give up much detail except noticeable limb darkening through even larger apertures but it's fun to try Have fun checking it out.

Freddie Posted July 16, 2012 Share Posted July 16, 2012 Paul, you should have no problem with a 200p. Go for it !! Link to comment Share on other sites More sharing options...
Charlie_132 Posted July 16, 2012 Author Share Posted July 16, 2012 im deffently going to give it a go soon, just the weather is frustrating me at the moment and not getting any better any time soon !thank you for all the replys thoughm helped me alotwill i basically just see it as a tiny blue pin [removed word] or will i see it more as a bluish disc ?

faulksy Posted July 17, 2012 Share Posted July 17, 2012 bluish disc but smaller than mars Link to comment Share on other sites More sharing options...
seigfriedwilson Posted July 17, 2012 Share Posted July 17, 2012 Both Neptune and Uranus are testing to find, but you'll know when you've got them.Wonderful planets to view. Not do much of the wow factor as Saturn, Jupiter or even Mars - until you realise the phenomenal distances involved.For fun, I like to work out the total time it has taken light from the sun to reach them and then travel back to me. Consider what you were doing when it set off on its journey.Seigfried Link to comment Share on other sites More sharing options...
