    Waiting With Anticipation!

    Mother nature hasn't been kind since I purchased this eyepiece. it's either been too cold or too cloudy. Will give my opinion after I'm able to use it.

    great 40mm 1.25" eyepiece

    I was looking for a 1.25" eyepiece that would give me a wider FOV than what I currently get with my orion 6" starblast. all 40mm eyepieces I've experienced in the past were lucky to have about 43 or 45 mm AFOV, so I took a chance with this TPO with 52AFOV. I tried it out on the Pleiades and it was pretty sharp enclosing the entire cluster. it appeared to have a wider FOV than my TV 24 wide field, thopugh the overall star images in the 24 were a little sharper. But this TPO 40 does what I had hoped. Will probably get a couple more TPOs.
