My grab-and-go outfit for the scope is a Baader Mk3 8-24mm zoom..

Quote:In my experience the ES eyepieces are good enough to do justice to your fine instrument, although they are a bit lacking in eye relief in the lower focal lengths. Yesterday I was out stargazing and was reminded once again what a fine eyepiece the 24mm 82* is in my 4" ED refractor. Personally the 24mm is about as heavy as I would go, but that has a lot to do with personal preference. The 24mm does have respectable eye relief for glasses, however, with glasses, you cannot take advantage of the entire field without moving your head around, so there wouldn't be a huge advantage over your Hyperion (at least for scanning the sky looking for targets). As for why not barlowing the 24mm and 30mm, yes, they are 2" ep's so that would require a 2" barlow which is more expensive, and then an adapter to barlow 1.25" ep's. Personally I feel that barlowing is for special occasions, when the seeing is good enough to crank the magnifications, and I would not want to be barlowing all of my ep's because of the inconvenience. It is possible that there may be some performance issue with barlowing the 24mm or 30mm that I don't know about, but I think the real issue is people normally just barlow to achieve high mag.Yes, plossls 20mm and up have decent eye relief so you could get a 32mm for your low power ep. Plossls are not bad finder ep's for eyeglass wearers since you can usually take in about the entire field of view while wearing glasses. As much as I like my 24mm UWA, that wide field is not well utilized when I wear glasses. For under 20mm, the Hyperions are not bad and would provide some consistency in terms of focus point with your 21mm. Or the Celestron X-cel series has long ER and a good reputation from what I hear. Maybe Zhummell Planetary when you get under 10mm. I like the Vixen LVW's myself, but even used they are around $150. Personally I find 180x to be the maximum useful mag with my refractor (or at least 225x is a little too much and loses sharpness). Yours is a little higher quality though so it may go a bit higher.
