New Meade 5000 20mm Waterproof eyepiece!
      #5941492 - 06/26/13 02:14 PM

Well,

It arrived today. The 20mm Series 5000 Meade 2" waterproof eyepiece! There are indeed typos on some websites about this eyepiece as it is a 2" offering. Looks to be in excellent condition. I wish the top cap wouldn't fall off so easily, but that's a minor thing, and I can fix it. The bottom cap is really stiff and is made out of thick plastic and fits really snug. Weight is 1.5 Lbs.

Once I have the time to get out with it, I'll report back here. I have attached a few pics of the eyepiece candy!

Cheers,

Eyepiece with the box


Field Lens


The 20mm Next to the 5.5mm for size comparison

Waterproof, eh? New to me. Well let us know how the optics are, as it's a Meade it should be good.

Well,

In my 10" reflector @ F/4.7 there was HEAPS of field curvature. I'm not talking just a little bit either. The inner 50% was sharp and the outer 50% had so much field curvature, I thought I had a dud of an eyepiece!

I had bought it based on a review here, but in my scope it was a big bummer!

I also own the 5.5mm Meade 5000 waterproof UWA and that eyepiece is amazing !!!!!!! That one is sharp right to the edges, and has excellent eye relief for an 82 degree eyepiece. I am not even remotely touching the top lens when I view with it. I guess they are not as good through the line?

In any event, I sold the 20mm Meade WP UWA two days after I bought it and I won't be missing it one bit.

I guess it just doesn't play well with short FL reflectors because the guy I sold it to hasn't tried to contact me saying it was a dud for him !!!


I have another 22mm LVW coming, (I loved my first one, but wanted to try something new in the 20mm-22mm FL range), and I am KEEPING this one because nothing compares with it except the 20mm Nagler T2 in my scope.

Cheers,

Mark,

It seems to be the case that eyepieces perform very differently in my Vixen 140NA than in your f/4.7 dob. In my refractor the 20mm meade only showed some mild curvature in the outer 10-15 percent of the field. I recall there was a similar problem with the 28mm ES68. Too bad! I love both eyepieces in my scope.

Dave

Right, in my 6 inch f/8 refractor they work really nice. Looks like you need a Paracorr, Marcus.
