    Default 2.5 or 5x tv powermate



    I see I can purchase either one of the televue powermates, the 2.5x and the 5x for about the same price. While I dont think I have any ep's that would work with 5x tv at this moment. Wow, I think that just answered my question....

    See, you guys are great. It's all about eye relief.....

    So the 2.5 is what i'd want for now, until I get some ep's with lower magnification....

    At least I think I'm getting it.....

    I almost didn't post this, but I guess I get experience points so I think I'll leave it, not to mention, If I'm right about the eye relief, It's because of the wonderful teachers I have here, and maybe someone else might read it, and say AUHHHHH, now I get it.

    Or someone will say I've got it all wrong...

    Getting the Powermate is a step in the right direction. You did good going for the 2.5x. Also, the Powermate is great to use for astrophotography.

    Yes, you got it right. I have the 4X Powermate and it works great with the real long FL EPs. I use it with my 30mm and 20mm all the time (50X=200X & 75X=300X), and when the seeing is really good, I can use it with my 14mm (107X=428X). It wouldn't be practical with any EPs with shorter focal lengths.

    The 2.5x is a good idea, personally I believe you get a better combination of magnification levels where the 5x will push you over the maximum useful magnification based on your OTA and atmospheric conditions.

    Unless.... You have a whole bunch of low powered EPs.

    I have the 2x Powermate and love it. I just need another EP and I should have my varying magnifications.
