    Default XT8 Eyepieces



    I am planning on getting a Orion XT8 in the not to distant future as a first scope. I know it comes with a Sirius Plossl 25mm eyepiece. I interested in planetary AND DSO observations so was curious what to get for additional eyepieces for this scope.

    Welcome to the forum and congrats on the upcoming scope. How much do you want to spend on an ep? Does the scope come with a 2 " focuser? If so this could be a cool ep for widefield viewing. And this for close up viewing. They both have wide fields of view so an object will stay in the ep longer without having to move the scope. Cheers.

    Not sure one a price range just yet, don't want to go too nuts beyond the cost of the scope for now. I know the XT8 can accept 1.25" and 2" eyepieces however (according to the specs I see online).

    I got an XT8 for Christmas and now have the following eyepieces:
    Orion 25 mm plossl (naturally )
    Orion Expanse: 6mm, 9mm, 15mm, and 20mm
    Orion Q70: 38mm
    Televue Radian: 5mm
    Televue Nagler: 22mm, 17mm, 12mm, and 3.5mm

    I'm in search for either a 8mm or 4mm Radian and after that, I think I will be done.

    I guess a better question right now, is what difference the various eyepieces will make for various kinds of observations.

    Good choice. I love my XT8. As for the eyepieces it depends. Planetary and DSOs are two totally different demands. Also, everyone has their own preferences and the amount you have to spend is also a huge factor. The best thing to do at this point is get a 10mm Plossl and a decent barlow lens. You'll have the 25mm that when barlowed is 12.5 and a 10mm which barlowed gives you 5mm for close ups of planets.

    Take it easy, don't empty your wallet out on EP's right away.

    Excellent, that for s the suggestions. Sounds like the Barlow lens will be a gooe investment to get some more versatility. Don't want to go too nuts..so maybe 10mm and a nice Barlow will do me for a bit.

    I was in your shoes just a year ago. I'm just trying to keep you from throwing money away like I did. Lots of people told me not to go crazy with EPs and I ignored them. I bought a lot of bad and mediocre EPs and useless filters and ended up selling all of it to get some decent stuff.

    My personal recommendation would be to get a Televue or an Orion Ultrascopic barlow, both are around $100. For starter eyepieces I would recommend University Abe Orthoscopics on a budget are about $70 a pop and are much better than the Sirius Plossl that came with the scope. Otherwise, Televue Plossls are another good choice that run between $100-$75 a pop.

    However, there are much more experienced people on these forums than myself. So get a few opinions.

    Hi Scott,

    You might want to consider the XT8i instead of the XT8. While both will give you great views, the i version comes with some extra accessories you may end up buying anyway which make the $200 extra cost a great value.

    The XT8i includes these extra items the XT8 lacks:
    • A 9x50 RACI Finder (value $85)
    • A 10mm plossl eyepiece and a 25mm plossl - XT8 only has 25mm (value of 10mm plossl $46)
    • Intelliscope (not sold separately)

    This means you only pay $69 for the Intelliscope feature that gives you push-to technology to find over 14,000 night sky objects.

    I really enjoy my RACI finder and I use it with a Telrad. The combination of the two are a lot more powerful and make it easier to find objects than the simple red dot finder that comes with the XT8 even if you don't use the Intelliscope function.

    If you do the XT8i and get a 2x barlow, this will give you the equivalent of 25mm (48x magnification), 12.5mm (96x), 10mm (120x) and 5mm (240x).

    In my case, I purchased the Baader Hyperion 8-24mm Click Zoom and it has been an excellent choice for me.

    Actually, it's funny that you mention that. I was discussing this with my my wife and she said if we're going to go for the XT8 then we may as well go 'all the way' to the XT8i and as you mention the extras that come with it, including Starry Night. and having the 10mm as well as the 25mm will give me a decent starting point and can wait to invest in some decent eyepieces.

    Thanks all
    Scott
