    Default My Eyepiece Education



    I’ve now spent a dozen nights observing with my new Meade refractor and can tell you what I’ve learned about eyepieces and filters based on this limited experience. I have yet to travel to dark skies for a deep space observing session, but that will be coming up soon. Of necessity, it’s been moon and Jupiter viewing of late. In the attached photo, I’ve divided the eyepieces into three groups, based on when I bought them. I put the two filters out in front, so I’ll comment on them first. When the scope arrived, so did a second package containing a Meade moon filter. It has 13% transmittance and does a great job cutting down the brightness of the moon. The Meade yellow #8 has been less useful, but might be great on Saturn. I was hoping to use it to cut down on purple fringing, but my scope has almost no purple to be seen! Instead, bright objects might show a fine line of yellow. The yellow filter actually intensifies this. For less than $10 shipped, I’m glad to have it, but it has been limited for now. For this year, these are the only two filters I intend to buy.

    The front row of eyepieces shows the two silver-top plossls that came with my Meade. One is 26mm, the other 9mm. To the right of them is a 15mm Meade Super Plossl and a Meade #126 short Barlow. All of these have been very good. The cheap silver eyepieces are as clear and sharp as any eyepiece I’ve looked through! However, my brother complained he had to take his glasses off to use the 9mm, so that lead to my next round of purchases, shown in the middle row.

    On the right, in the center row, is a Russell 19mm Konig. It has a lousy eyecup but excellent glass! Stars are pinpoint to the edges. Barlowed, this gives me a 9.5mm equivalent with fairly long eye-relief. It satisfied my brother. The eyecup is too stiff. I folded it down, a few times in the winter, and it started to crack. I now just keep it up. The Konig has a 70 degree field of view that I like. Center row left is a Russell 2”, 32mm Super Plossl with a Delrin body. At $52.65 shipped, it’s my most expensive eyepiece. I love looking around the sky with it, so it should be good when I get in dark skies. It’s the only 2” eyepiece I plan to buy.

    Finally, we come to my last eyepiece purchase for the year. Back row right is a the new red line Svbony Long Eye-Relief eyepiece in 9mm. That one was purchased for my brother’s ease of viewing. I figured I’d Barlow it to 4.5mm, so he could get a better view. It sucks, lol! Very bad kidney beaning. The seller sent the gold line, on the left, as a replacement, and that one sucks too, lol! Both kidney bean the same. However, I can get them to work to where I can get nice, yet fleeting, views.

    In conclusion, I’m happy with my purchases, except for the last eyepiece. I can still use the red line and can easily gift out the gold line to my astronomy pals. I’ll find a scope it works in. I’ve decided it’s best not to spend money trying to make others happy. If you have a spouse or other family member who wears glasses and could just take them off and won’t, they’ll be happy enough with inferior views, lol! Just buy what makes you happy. For me, I’d be happy enough with nothing more than Meade Super Plossls. I think they’re nice in my scope.

    I have the Meade Supers in 26mm, 32mm and 40mm, and they are tack sharp in my F10 refractor. I was very impressed with these since I picked them up on sale a few months ago.

    The gold line I believe are the ones similar to Orion's expanse? Now those, I've been generally unimpressed with until I got the F10 refractor. I actually think they work rather well in that telescope and while the image quality is not as good as the 4k's it is worlds better than what they produced in my F5 dob and i80. I see so many bad reviews of these Expanse clones that doesn't exactly match my experience with them, makes me wonder if there is something to the claim that the Orions are subject to a bit tighter quality control than others.

    Regarding the SVBony LER: Anybody know who makes these? I'm wondering if they are the mysterious GSO LER eyepieces on their website that has been saying "Coming in May" since well before last May?

    The 66 eyepieces have been around for a very long time, I would hope that GSO is making a much better offering.
    They were most likely originally inflicted upon us by Barsta.

    I don't know who makes the Svbonys. I thought maybe Synta. I'm glad they're ok in an f10 refractor, but the 9mms suck in my f8.3, lol!
