About LinkBacksHi everyone.
Would anyone that owns any or all of the ES82 eyepieces be kind enough to weigh them for me in grams please? I'm making a box to keep my eyepieces in as and when I get them. I've decided to aim for most, if not all, of the ES82 range as I was very pleased with the 8.8mm when I first looked through it. I've ordered the 11mm and 18mm from a shop in the uk, ready for me to collect from my parents house in a few weeks when we fly over for a visit. But the shop states one weight and explore scientific state a very different weight. I'm in the process of organising where each eyepiece will fit into my box so that the weight inside is evenly distributed.
Thanks in advance

Re: Weight of ES82 eyepieces...
Not sure this will help but here are the weights of mine.
18mm - 4.2 ozs. - 119 gr.
24mm - 1.83 lbs - 830 gr.
30mm - 2.4 lbs. - 1088 gr.
I weighed in lbs and did conversion online. Weights include EP guards. EP site says 30mm should be 1007.shackybracky and omeek like this.John...... Listentothestars.net

Re: Weight of ES82 eyepieces...
The weights of all the ES eyepieces are listed in the ES website.

Re: Weight of ES82 eyepieces...
The OP was asking since the ES site weights differed from his shop. And my ES EP's do weigh a bit more than the ES states.

Re: Weight of ES82 eyepieces...
Ok, I think the difference in your guys' data may have just indirectly detected another gravity wave or something.
Anyway, as Lowjiber stated, the ES website has the weight listings. They are even in grams just like the OP is looking for. That said, like the other John said, the ES data might not be 100% accurate but, should be close enough.

Good catch. I was punching numbers in to Excel as I weighed and simply copied them over. I forgot I had the auto decimal feature turned on.
I'll blame it on the coffee not having kicked in yet. Bryan

Re: Weight of ES82 eyepieces...
Guys,
The weight in grams can't be with the decimal point.
I have the 24/82 on my wish list, according to the es site it is 24.8 oz =704g
That's why I haven't got it yet - too heavy for my ES 80ed.

Re: Weight of ES82 eyepieces...
A curious statement, why do you feel it will be to heavy for your scope? I regularly use heavier eyepieces in my 80mm with no issues. Originally Posted by jpaulo Refractors: Antares 105 f/15, Celestron 150 f/8, Stellarvue NHNG 80 f/6.9, TAL 100RS f/10, TS 102 f/11, UR 70 f/10, Vixen SD115s f/7.7
