    Default Celestron Luminos 15mm vs Ultima Duo 17mm. Your choice?



    I had set aside around some money to add a mid-range eyepiece in between a 12mm X-Cel and a 21mm Hyperion. Which one makes more sense?

    The 68-degree 17mm at around CDN$95

    pros: on sale right now, so cheaper; similar to Hyperion so I can use finetuning rings (and sell my 12mm and 9mm X-Cel)

    The 82-degree 15mm Luminos around CDN$130

    cons: likely bigger TFOV

    if you can choose only one between them?

    Suggestions?

    P.S. I know some will say "Neither!", but... thanks, TVs, Pentaxes, ES are a bit beyond me. I still need to set aside budget for a search eyepiece that maximizes the FOV for a 1.25" barrel (maybe a 24mm ES or Stratus, unless I go with a 32mm plossl)

    If I were going to consider the Luminos, I would just kick in the extra for the ES 14mm 82. If I couldn't do that then I would consider the 17mm UD, but I would probably look further because I would keep the 12mm and 9mm X-Cels.

    Luminos 15mm will work nicely in your scopes. In my 8" SCT I preferred it over 14mm ES 82 which I sold eventually.

    It is also spaced nicely from your 21mm by 1.4x. 17mm is only ~1.2x from your 21mm, not enough difference to justify purchase IMO.

    Interesting perspective, I thought of that too. On the flip side a 17mm is ~1.4x from the 12mm, whereas the 15mm would be 1.25x from the 12mm. So spacing wise, it is a wash. I guess it is a versatility/parfocal/cost vs TFOV thing. I kept on wondering why the regular price of a 17mm Ultima Duo is a lot higher than the 15mm Luminos (knowing that 15mm actually will give a bigger TFOV) and wonder if there is something about the merits of the eyepieces that I am not aware of.

    Never tried Ultima Duo, but my understanding that it should be similar in performance to Hyperion. I did compare Luminos at one point to Hyperion and find them of similar optical quality, except FOV of cause.

    I don't recommend EPs which I have not tested at one point, so I would stick with Luminos recommendation.

    Maybe someone with experience in Ultima Duo can comment.

    I haven't used the Ultima Duo, but it is my understanding they are the same as the Hyperions, which I did have until I started getting faster scopes. With the SCT and long refractors, the Hyperions were fine, not so with the faster scopes, especially the fast Newt.

    Pretty much everywhere: The ES website, and typically when these sales happen, most astro vendors reflect the sales pricing on their own websites, in the US at least. Not sure how Canadian vendors do this, though.

    Agena Astro, High Point Scientific, OPT, etc., typically lower prices accordingly.
