    Default Help with high power EP...



    I got my XT8 just about a week ago and it came with an Orion SP 25mm EP. I already have a 10mm SP from Orion but I'm not satisfied with my high power views of the moon. At 120x with my 10mm EP, I can see many little craters but I want more power!!! I was thinking about 170-200x which is about a 7-6mm eyepiece. Any suggestions?

    My budget is about 70$ right now but I may buy either 2 eyepieces with 125$ or a glass solar filter which will eat it all up in one purchase or an eyepiece and a film solar filter. Having trouble debating that too... any help? Film or Glass?

    A 6mm should be ideal for high power views, since your scope is an f/6 (this gives you a 1mm exit pupil). As far as eyepieces go, with a $125 budget you would do very well with something like this: Meade Series 5000 HD-60 - 6.5mm - 1.25" - OPT Telescopes or like this: Explore Scientific 6.7mm 82° Series Waterproof N2 Eyepieces - OPT Telescopes

    The wide field will be good to prevent having to constantly bump the scope, and the complex designs correct for spherical aberrations.

    On to the solar filter -- in my opinion, don't bother with the glass filter. A film filter in a cell you build yourself (see here: Build a Solar Filter for Your Telescope) is just as good and will cost you less than $20.

    Skaven pretty much took the words out of my mouth and added some links for you aswell, my only other suggestion to that is you could also look at the Celestron X-Cel LX 5 or 7mm...in your scope the 7mm might be better for you though. The X-Cel LX and meade HD-60's are the same eyepiece pretty much but the X-Cel LX can be had for $65 compared to $80 for the HD-60....if you are on a tighter budget and dont mind the look of the X-Cel LX. But yea I would not waste your money on glass solar filters...much cheaper to buy film and make your own.

    i like the badder or es ep`s, for me as a glasses wearer i like the wide field 68` to82` in that range with 20mm eye relief. if you dont wear glasses its a little less important only know that with a 5 or 6mm ep a plossle for instance is going to almost have to be touching your eyeball to the lens get a good view. i just purchased a used but like new 4.8 nagler for 100usd and am hoping it will be a good match for high mag viewing in my comet hunter. so with a little looking a great used ep can be had at a good price. another plus for the wide fields would be less bumping to keep it on target, at high mag the moon will sweep threw the fov pretty fast.

    What magnification do you get when use use that eyepiece with your telescope. I think I decided on this eyepiece from Orion:6mm Orion Expanse Telescope Eyepiece | Orion Telescopes: Eyepieces. The true FOV is about 0.33 degrees with my scope and gives 200x. I had a 4.5" newt and I pushed 228x with an old 4mm .965" eyepiece and Saturn swept through the view in about 2 seconds. According to my scope calc, the transit time with the Orion EP will be 79 seconds at 0 declination.
