    Hi robbo,
    Welcome to the forum!
    It's hard to say what will come with your telescope. Most likely, the EPs will be usable. I may advise you to buy extra to them 25 mm EP , 2X Barlow and some 6mm or 8mm eyepiece. That would be the perfect set for the first time.
    Clear skies,
    Michael

    it will probably contain a 25mm ep when it comes,possibly a 9mm
    too.get a 2x barlow and a moon filter,then get some practice
    with it for a while before deciding what other ep's to go for.

    The 130 SLT comes with 2 eyepieces... a 25 mm and a 9 mm....neither are what I would call very good eyepieces BUT both are very serviceable...

    Unfortunately the 130 (650 mm f/5) is designed more for its wide FOV then its magnification (great scope to use on Open Clusters etc under low power...) although on good nights with good seeing conditions it should be able to be pushed up to 250x especially on the moon...

    Personally I'd be looking to buy a 2x barlow and a CHEAP 8-24 mm Zoom eyepiece like the Zhummel or Celestron and HOLD PAT for at least a few months just using teh 2 eyepeices that cam with the scope and the One Zoom eyepiece and the barlow...

    after you have used the scope for a few months you should be able to figure out what you like to look at and what eyepieces you will need to be able to put a smile on your face,...

    Go slow GO as cheap as you can for now...OR drop about a 100 bucks on a Celestron Eyepiece kit KNOWING that it will have a high educational value and that within a year most of the included eyepieces will have been replaced...

    BTW...get an external powwer supply NOW...Wal Mart sells jump start battery chargers much cheaper then you can buy a Power Tank...

    I Love open clusters so I'd love your scope...

    One of my latest add-ons was Orion Edge-On Planetary. You may find them on each side of 100$ range. From cheaper ones - GSO brand will give you bang for buck.

    There are two trains of thought about the eyepiece kit, and many who have owned them at one time or another will say skip the kit (they are just like the stock EP's; if you're going to spend some $ might as well step-up in terms of quality; I've had the kit and the ones included of lower focal lengths are hardly useable because of very tight eye relief - replaced them almost immediately) and instead consider the other myriad EP's available today which will let you enjoy astronomy better than the stock or EP kit, look here for a very good alternative (also has a bit about the merits of getting a kit):

    Zhumell Planetary Z's

    The best EP education is to listen to those who have owned the kit and shared their experience regarding their use, and it's free and won't cost you ~$100+ just to find out that you want something better.

    Best,

    Hernando

    Hi robbo,

    Many scopes come with a 25mm EP to start with, but, I can't honestly say which EP you'll get with your scope. Is it a decent quality? It should be good enough to get you started!

    However, you can get some pretty nice EP's for under $60. You don't always have to spend hundreds of dollars to get a quality EP.

    I've purchased the bulk of my EP's through Orion Telescopes: Save on Telescopes & Binoculars! - Telescope.com and I've always been pleased with their EP's, and they have QUITE the selection. Not to mention, very good prices. There are many good EP's out there for under $50ea!

    I would look for maybe 1 or 2 EP's. Maybe a decent 25mm, maybe a 12.5mm??? I would think that should be a good start.

    Just my 2c
    Chris

    The Zhumell Z planetaries are equivalents of the:

    Orion Edge-on planetaries
    Orion 6mm Edge On Flat Field Planetary 1.25" Eyepiece - 8883 - OPT Telescopes

    AstroTech Long-eye-relief
    Long Eye Relief

    or the William Optics SPL Super Planetar Long-eye-relief
    William Optics - SPL 3mm / 6mm / 12.5 mm

    Probably there are equivalents in UK under a different brand name, just get one from a reputable dealer; check the specs if they match.

    I have the light pollution filter but don't use it much - don't think it has any significant effect on the light polluted skies here; try it out first by attending a star party and see if you like it before buying.

    Best,

    Hernando
