8mm Plössl by Carton ($20.00 USD)

Great views, terrible Eye Relief!
Recently I happened across a pair of 8mm Plössl by Carton. They're a great Plössl and for $20.00 each, brand new, they're a steal!
A Drift Test showed this eyepiece has a little more than a 45° FOV but there is very little edge aberration. There's only the slightest amount of softness at the very edge of the FOV. Most inexpensive Plössl that claim a 50° or 52° FOV have at least 10% edge aberration in shorter focal lengths so they really only have a 40° to 45° Actual FOV - so don't let the narrow FOV the test showed fool you. Detail and Contrast are very good with excellent light transmission. This eyepiece doesn't enhance CA like some of the less expensive Plössl I've tried. With an f/7 achromat on the Moon there was very little chromatic aberration, just the slightest of fringe on the outside of the Moon and nothing noticeable at the terminator. Viewing the Orion Nebula the eyepieces are as good at showing detail as a pair of TV 7.4mm Plössl. I haven't had a chance to try them out on a good planetary target but I suspect they'll do fine.
The drawback to this eyepiece it's the eye relief & eye point. Eye relief is only a few millimeters and it blacks out moderately. If you wear glasses you're not going to be able to use this eyepiece and you won't like it if you're a novice who's not used to holding eyepoint. There are no filter threads on these eyepieces but I found the barrel is the same thread as some inexpensive Meade MH eyepieces I had so I could swap the black, Carton Barrel without filter threads for a chrome, Meade Barrel with filter threads.
Without comparison testing it's hard to say but my feeling is that high end Plössls will out perform this one. Then again for 3 or 4 times the price you'd hope they'd do some things better. Overall this Carton 8mm Plössl is a fun and inexpensive Plössl eyepiece.Sort by
