    Wink ES 18mm 82deg?



    Opinions please on the 2"ES 18mm 82deg eyepiece? I have the 30mm and 24mm 2" siblings with which I am very pleased. Need an image scale to fit between the 24mm and my 1.25"ES 11mm 82deg, but am keeping clear of the 14mm due to its varied reviews. Just wanted to hear how this ocular performs in sub f5 optical trains, and compares with its siblings. Seems the Explore Scientific eyepiece sale is still on?

    I just used my 14mm tonight in my f/4.9 Dob and I really liked the views and how this EP performed in the scope. But I have heard the 18mm is also very nice, the 14mm would be cheaper though..something to think about.

    I have the same EPs as you plus the 18mm. I can tell you that is my least used premium ocular. I'm using a smaller and slower dob so YMMV. The EP gives great views with very little pincushiony distortion even in the Barlow. But therein lies the issue. The 18mm has little to offer as far as views go over the 24mm and Barlows to 9mm which is pretty darn close to the 11mm you already own. I realize this doesn't directly address your question about it's performance at your speeds. Just thought it'd put it out there for ya.

    I have the 18mm ES82 and use it in my f/4.7 10" scope. Fantastic eyepiece. I've never seen through the 14mm 1.25" model, so I don't know how it compares.

    Hey sopticals
    I have the ES 18mm and I find it a great EP. Even though I use my 24mm more I find that I often slide in the 18 because I really like to frame what ever I'm viewing and I want to kick up the mags a notch to accomplish that.
    On thing I have found with this EP though is that I can't thread my Baader OIII filter on completely. I can with the other ES EPs' I have but not this one. I wondered if it is because of the painted/coated inside the barrel. The 9mm the 24mm and the 30mm have a different lens configuration /setup so there is no paintcoating. I mentioned this at the scope store and this was the first they heard of it. In fact they never noticed the diffence between the lenses. "Just thread it on until it's secure" I'm told. Well ok but that doesn't solve the issue. Maybe it's a one time flaw although I kinda doubt it.
    The EP is a good one and I can live with the filter thing when used together every "blue moon".

    Regards
    Bob

    While trying to decide what EP to buy sometime ago I asked KT4HX his opinion about the ES line and he responded with a detailed report about his experiences with the line. I recall him giving high praise to the 18mm EP as his go to piece. At that time I believe I either had one ES eyepiece or was about to purchase my first one. Since I had two refractors I was looking for more power so I started with the 4.7mm and 6.7mm. I then bought an 11mm as more of a mid range for what I had in scopes, but the EP game changed when I picked up a CPC1100 SCT recently. I'm now headed in the other direction favoring the 1100 by buying both the 18mm and 28mm 2" EPs. I'm even considering purchasing a barlow to add more flexibility to the lower power EPs. Unfortunately, I haven't had the cooperation of the skies recently and that includes the full moon, so they sit. It won't be until after Sept 18th that I'll have a chance to try them and wished I could so I can offer some feedback to you on the 18mm EP. However, based on other reports and my own experiences with the ES line, I'm confident the EP will be and excellent performer, especially in the CPC1100.

    I have the ES 82*'s in 6.7, 18, and 24. I haven't had a chance to work too long with the 18 (my most recent purchase), because of a month of fires and smoke, but as much as I have used it, it seems the equal of the 24 (which I love). I use a ED 2" Barlow (GSO-type) and probably won't purchase an 11 or 14, since the Barlow gives me those mags. They work very well on my refractor, and even better on my Dob.

    I have the ES 20mm 68*, but wanted a wider FOV. I was going to go for the 18mm 82* but I got a little nervous with some folk saying the eye relief was tight. It certainly is smaller than the others. In the end, I took a deep breath and ordered the 20mm 100*, its somewhere over the Atlantic as we speak......
