Hi Everybody, 

 

I've had my Meade{made in Japan with no undercuts}zoom for a few weeks now and have been able to view Jupiter a few times using my TV 3x barlow from 24mm to about 16mm in my Arcturus binos before the seeing{clouds, wind} got in the way.  Wondering just how much better the zooms would perform in "better"{at higher powers} binos on the moon and planets other than being capable of using wfo eyepieces?

 

I've only been able to compare the zooms while looking at Jupiter to the 32mm eyepieces that came with the AB and the zooms to me are sharper.  I'm sure there are better eyepieces but the convenience of the zooms have me won over. Hopefully, someday I'll be able to get a pair of Baader Mk IV.  

 

 

 

Clear Skies,  De Lorme

I bought a set of Arcturus bino's as a present for a friend. Before handing them over, I checked they were functional and the image quality was not obviously different from my Mk V's. The collets worked well. The only part I didn't like was the 1.25" nosepiece but an adapter to connect them to the T2 system is available.

 

Of course, the potential field of view is not going to be the same. When you're looking at planets, neither matters but the vignetting may cause an issue on the moon - it really depends on how large your eyepieces' entrance pupils are.

 

IIRC, the optical path length was about 100mm and the clear aperture was 22mm. This means they will start to vignette the whole field at f/4.5. For comparison, the Mk V vignettes the whole field at f/4.3 so there's not much difference there.

I have a pair of similar Chinese BV by WO and then upgraded to the Denk II BV. Initially I did not see a big difference on the moon, but the larger prism's worked better on DSO, clusters ect. Premium product for sure, bu for $200 for the Chinese BV is a good way to begin.

 

Where the Denk's really outshine them all is the Power Switch, killer App.

Hi everybody,  

 

Good news,  I was able to buy an original Denk standard with the single power switch here on Cn.   Should be here by Wednesday just in time to view the moon.   Not quite as good as the Denk 11 but I'm sure there better than the Arcturus of which I just sold.  Really looking forward to seeing how well the Meade zooms perform with the standard Denk.

 

Anybody here used these before?

Beg,  Do you remember the highest powers using the original Denk on planets and with what eyepieces and scope?

 

Using two eyes has me spoiled now and convenience is a way of life{LOL}  I sold my Baader Zoom which I  really like until I started using bino's to fund this purchase. So hoping that the Denk with the Meade zooms will take me to over 300x on the moon and Jupiter.

Oh man, that was many years ago. And I've always used my BV'ers more for clusters and and deep sky. Back then I used a 120ST and an 8" dob. But I remember that it was sharp and excellent on the moon.

 

Just loved scanning the star fields with it, and it was a great compliment to my 20X80 binos back then. Believe the only real difference between the standard Denk and the Denk II was the coatings. Denkmeier has always had a good rep, so I think that you will like it.
