I can't imagine a better deal than this Meopta-made scope from Cabelas. It's the S2 with a NON-removable 20-70 eyepiece. For a $1,500 budget, how can you beat it?

http://www.cabelas.com/product/hunti...1.uts?slotId=3

P.S. It's no Kowa, but it is half the price. And it doesn't have the 30-60 like Sancho's (and mine) but I HAD to mention Cabela's sale so that at least someone here could snap one up.
That is a fantastic deal and OP should have a look. Why can't the ep be removed? (Not that it matters, I don't think there are any others available apart from the two zooms)

Hello Sancho,

Whats the price you are asking for your S2? Sending to Barcelona, Spain, should be easier, I presume...

Thank you!

Thanks for the input guys. Cabelas did have some great deals. I purchased the Kowa and got a very nice discount from a US retailer. The 1.6x extender was the the deal closer for me. It should be here Friday.
Thanks,
Dave

Wow! What a difference. I picked up the Kowa today and there is no comparison to the Nikon.

The sun was coming up in the direction I was looking so that makes things washed out. The color comparison from Nikon to Kowa is drastic. The Nikon view was drab but the Kowa was still vivid. I could pick out a lot more details with the Kowa. And, that zoom eyepiece is impressive. The whole package oozes quality.

The overall viewing experience is WOW level. Awesome.

Thanks for a great forum to hash out all the details of the different products. I'm going to be happy with this one for a long time.

Dave

Congrats on new scope...there are few things more satisfying long-term in life, than new optics or new bicycles. As a matter of interest, what model was your old Nikon scope? If it doesn't say on the scope, can you post a photo?

Also....bloody hell...that beach-front deck...do you live there? Can I be your Butler?

Just for clarity - which Kowa did you purchase?

Hi,

It's the Kowa 883 with 25-60 wide angle zoom. The Kowa is much heavier than the Nikon PROSTAFF 5 Fieldscope (20-60x82mm).

Yep, that's my lanai. I live on Kaneohe Bay across from the Marine Base.

I was looking at a stop sign at the Marine base 2 miles or 3.2 km away. I can read the sign when it is in the middle of the field of view. But, if I move the sign outside the middle...towards the edge (but not far edge) then "STOP" become blurry. I have to adjust the focus slightly to read "STOP" again. So the focus is different for the sweet spot in the middle and outside that sweet spot. I'm curious if that is normal?

Thanks,
Dave

Thanks for the further info. I thought you were going for the 663M. My understanding of the various reviews is that the 883 is generally regarded as the best spotting available at the moment. I am afraid I cannot help you with why the focus needs to be adjusted for things on the edge of the FOV. Best leave that to peeps who know what they are talking about.

SuperDave, post 33,
That is a quite common optical aberration in which the focus from center to edge is on the surface of a sphere. By using a special optical construction (flat field optics) that can be eleminated, but that is more expensive.

Thanks guys. I'm glad to hear that the center / edge focus is normal.

I'm very satisfied with the scope. I'm waiting for the 1.6x extender and need to order a phone holder so I can get some photos. Have a good weekend,
Dave

Hi,

I agree that this effect is normal for a fast refractor without correcting elements but it is certainly not spherical aberration or SA but field curvature or FC. The former would be a flawed instrument, the latter is normal and its radius is around 1/3 of the focal length for most two and three lens objective designs.

Hi Joachim,

Say what? You went way too deep for me to understand.

Can you translate for my simple mind? Do you think my Kowa is acting normal? (YES/NO) :)

Thanks
Dave

PS. The 1.6X extender came in today and the max zoom is very impressive. I'm so impressed with Kowa.

Hi Dave,

the effect you see is normal and called field curvature (FC). It could be corrected with extra elements in the body or the eyepiece but isn't in this instrument.

Zoom Digiscoping

Hi everyone,

The Phonescope arrived this afternoon. Here's some photos showing the zoom from 40 to 95x. I reduced the photo sizes to fit the upload requirements but did not crop them.

I put the phone on Auto Focus lock so I could adjust the focus on the scope. But, it's hard to tell if it's perfectly focused on the iPhone screen. I'm impressed given the distance.

The helicopters are about 2 miles away from my house. The photos were taken around 3:15PM and it was overcast.

Thanks,
Dave
