Sirius Plossls offer a 52-deg apparent field of view for clear, sharp images. In most cases, these are eyepieces that are focused on wider AFOV or better correction for low focal ratio scopes.

All are good eyepieces and diagonals, and would be excellent for star party use. Gold Line eyepieces also offer better eye relief than Plossl eyepieces, especially at the shorter focal lengths. 32 mm = 18.75X 16 mm = 37.5X (32 mm eyepiece with a 2X barlow), 12 mm = 50X (If you have a 25 mm that came with your scope, use Barlow for 12.5 mm), 4 mm = 150X (8 mm eyepiece with a 2X Barlow), 3 mm = 200X (6 mm eyepiece with a 2X Barlow), 24 mm = 25X (the low power end of the zoom), 8 mm = 75X (24 mm zoom setting in a 3X Barlow), 2.66 mm = 225X (8 mm zoom setting in a 3X Barlow), True field of view or FOV = Apparent field of view (AFOV) eyepiece / magnification. Pay attention to the eye relief, especially if you will be observing with glasses. Worth it is a tough question to answer. I have just one Meade product currently and that is a series 4000 1.25 inch UHC type filter which I use for outreach. Other than the limited AFOV, which you are apparently fine with, and limited eye relief in the shorter focal lengths there is certainly no reason not to choose Plssls.

If you are going to wear your glasses when you observe, you want at least 18 mm of eye relief and 20 mm is better. If that surface is wobbly the scope will be almost useless. Stargazing Help is a participant in Amazon Associates program. To estimate the highest practical magnification for your telescope, you take the aperture in millimeters, mm, and multiply it by two.

Kellners tend to have narrower apparent fields of view (40 degrees rather than 50 or 52 degrees in a Plossl), and in short focal length telescopes (focal ratio f/5 or shorter) they can have more false color fringing, but for the most part it is hard to notice the difference between a well-made Kellner and a well-made Plossl in terms of image quality. 100-300X, 2X Barlow. This would definitely matter to observers who wear eyglasses when viewing. I often recommend it. Thanks so much. No price limit.

It offers good color correction and high-contrast images. The Plossl's are very easy to modify, allowing me to use the bino-viewer on, all my refracting telescopes without having to cut down the tube length, p.s. For planetary viewing, comfort is essential in helping to increase viewing time .

Optics manufacturers began selling and popularizing Plossl eyepieces, albeit with a generally simplified design where each achromatic doublet had the same focal length.
