    Default Got my new eyepiece! ES 82 degree 30mm eyepiece



    I just received my new ES 82 degree 30mm eyepiece via UPS today. It's a thing of beauty and also a real beast of an ep. This thing is huge and heavy. It would make a dandy bludgeon if I ever get bored with astronomy. The only bad news to report is that I don't know when I'll get to use it. The clouds here will just not go away! I've had my Orion XT8 for a month now and have only been able to use it twice because of the weather. I'm really anxious to experience some immersed views of the night sky but guess I'll just have to be patient a while longer.

    I do have a question for anyone that has a telescope like mine and this eyepiece. Someone on this forum said that they could not achieve proper focus with this ep without pulling it out of the focuser a bit. Has anyone else had a similar problem?

    Thanks, Kim

    I have the 100 degree versions and have to pull the eyepiece out a little to achieve focus with my XT8. No big deal, I just secure it a little further out and get great views.

    I have that exact EP claws and I am thinking you are going to love it...

    I have an f/6 8" dob similar to yours so you should be about 40x, you will get around 2* TFOV and be able to fit four moon diameters in the FOV hehe

    Once i get mine in the focuser it's hard to take it back out as its so pleasing to use, the clarity and huge FOV are really cool. I am confident you will enjoy it as well.

    Good luck and be sure to let us know how it goes when you use it for the first time.

    Congratulations! The ES are a great series and you probably have chosen the best amongst it. Should provide plenty of sweeping views.

    I had to add counter weights to my scope to be able to hold the huge thing. You could kill someone with it lol.

    I was wondering about the weight myself. I don't know if the spring tensioners on the vertical axis of my XT8 will be strong enough to hold the scope with this ep. Given the physical obstructions around my back yard my OTA will never be below 30 degrees from horizontal. I guess I could set up the scope in my living room and answer my own question though. I was waiting to drag it outside for some viewing but the weather here just will not cooperate.

    I can confirm for you that the springs aren't going to cut it. I have a steel clamp bungee corded to the end of mine until I get a chance do something better.
    The EP is excellent imo. It's the first EP to show me nebulousity in M45 for my red/orange backyard. The 2 degree FOV is ever sharp all the way to the edge.
    I did post on here that you have to pull the EP out of the Focuser. Make sure you tighten the screws on the flat part of the barrel. The first time I did it in the dark the who's heavy sucker slid when i brought my eye to it. Freaked me out a bit.

    Congrats on the new hand grenade. It will treat you right. Especially under darker skies.
