    Swarovski SLC. Zeiss Conquest Nikon MHG and Vortex Razors 10x42

    Ok, here goes.A couple of years ago I sold my Optolyth 12x50 and my Bausch and Lomb 10x42, Both were 30 years plus old and not weather proof. So I started look at some new bins, Vortex Razor, Zeiss Conquest and the Nikon MHG seemed to be the top three in my price range here in the UK. So I...

    SLC diopter

    Just bought a pair of used SLC 10x42. Not had chance to look through them yet, but the diopter doesn't seem right. When you centre it, it will only turn to the left and goes past the markers. It won't turn to the right. It's 42 clicks from left to right and when count 21 clicks it centres at +...

    The Defintive Answer.

    Does the Baader MK1V reach proper focus on the the Pentax PF80/65 spotting scope? Yes and no. The MK1V comes with two adapters s for the 1.25 nose piece. One is flat and one has a shoulder on the inside as you can see in the pics. My understanding is you swap the one with the shoulder for the...

    Diopter Settings?

    Just got two pairs of Vortex Razor Bins, 8x42 and 12x50, both give really nice views, delighted with them. However, when I set the diopter one is minus and the other one is plus. I know it doesn't matter once it's been set, I just wondered if anyone else found this with any their bins. In theory...

    Is it me, my eyes, or what?

    After nearly 30 years with my old bins I decided to sell the old stuff and buy what will be my my last pair bins. Like you do, you trawl the forums and try to get an idea of what's hot and what's not. We all know that a lot of what is said on the internet is absolute rubbish, with no foundation...

    Zeiss Conquest 8x42 vs Vortex Razor 8x42

    Ok, I've read so many post on the internet regarding the Vortex vs the Zeiss I decided to buy a Conquest and do the comparison myself. Just ordered a pair from Wex, exactly the same price as the Vortex, £680. Apparently, to some people the Conquests "blow the Razors away". Night and day. It's...

    Avalon 8x32 or Nikon Monarch 7 8x30

    Avalon bins, any good. Looking at compact 8x32 or Nikon Monarch 7 8x30. Anybody any experience with either of these? Avalon are 1/3 the price of the Nikons from what I've read they are very good though.

    Lemons?

    Before joining this forum it never crossed my mind that the scope I bought could be defective ( a Lemon ) Whenever I buy anything I always buy quality and I must admit, I am surprised that the quality of spotting scopes, especially from world class optic manufactures are subject to quality...

    Slider Plate?

    I'm looking to buy some sort slider plate so that I can move my Pentax PF80 a bit further forward. When I'm sat in the hide I have to lean back to get a proper view. Is this the type of thing I should be looking and any other suggestion would be most welcome. Manfrotto 357PLONG Long Sliding...

    BST Explorer Eyepiece?

    Just bought a 15mm BST Starguider EP. I already have a 12mm which is excellent, but not so good at the edge. The 15mm is much sharper than the 12mm at the edge. Is this normal with this lens or have I got a duffer? Also you can unscrew the bottom element and swap them over, when you do this the...

    Opticron have dropped the HDF 40809 ep?

    Looks like Opticron have dropped the HDF 40809 ep. Maybe they don't sell enough. I could understand it if the zoom was that good, but it's not.

    True Aperture?

    Quite a bits been said about the true aperture of spotting scopes in the past and recently. In particular the Pentax PF80ED. I have both the Pentax PF80ED and the PF65ED. With the PF80 you can clearly see the exit pupil reduce in size as you close focus. I haven't measured it, but it's...

    Focal length a Magnification?

    I'm here again seeking advice. If an EP gives you 37x on a scope with a focal length of 570mm, what would it be on a scope with 390mm? Also the zoom gives you 27x72 on 570mm what would that be on a scope with 390mm? The reason I'm asking is because I've just got my Pentax PF65ed11 and at the...

    Question for the expert optics members?

    If you have a scope with a focal lengths of say 450mm with a fixed 30x and lets say if has 100% resolution. If you increase the focal length of the scope the magnification goes up, lets say in this case to 40x. Does it still retain it 100% resolution? The reason I'm asking is this. On the...

    Hawke Endurance 85m ED or Kowa TSN883?

    The Hawke seems to get pretty good reviews for £550, so does the Kowa at £1950 Big difference in price, what would I be missing out on if I bought the Hawke? The scope wouldn't get heavy use and never used in a harsh environment. I'm tempted, any Hawke users on here? Ron

    Any of you guys use a filter?

    Whenever I've bought camera lenses, I've always put a UV filter, to protect the lens as much as anything. Any of you use a filter on your scope? Ron

    Baader Hyperion Zoom?

    I'm here again, on the Baader Zoom I have, when you unscrew the eye cup to get the max eye relief, it feels very loose and wobbly. When you get to the top, it so loose it comes off. You can push it back on again, but it's still the same. I have to tape it up to stop it moving, Is this normal...

    A huge tahnks to all the forum memers who have helped me.

    A huge thanks to all the forum memers who have helped me. Well. I finally got some decent weather to check my Optolyth Baader conversion. The weather wasn't brilliant, it was overcast, with showers, the sun even came out for a brief spell though. So was it worth it? you bet. The first thing I...

    Modern Zooms vs Fixed EPs?

    If modern zooms are that good, why do they still make fixed EP's? Some people say they are, others say, they're not. I've just fitted a Baader zoom to my Optolyth, and to very good effect, it really has transformed the scope. I was going to fit a fixed 13mm which would have given me about 35x...

    Astro Eyepieces on spotting scopes?

    Any one who's seen any of my post will know I'm not using a Baader Hyperion zoom in my Optolyth TBS80ED and to very good effect. When you look to buy these, they are specced different to regular scope EP's. I've been looking at some Pentax EP's, they're expensive, but the quality seems to be...
