    Anyone tried using an ND filter on sunny days?

    Thanks for the answer :) Yes old Harry Rocks is very close. I am right on the clifftop on the middle part of Bournemouth Beach, I can see Old Harry from from my balcony window. Would be great to see Peregrines. (Maybe I already have but didn't know it). Do Peregrines hover like Kestrels...

    Hello from Bournemouth UK

    Hello. It’s funny I came to the forum for the binocular section for the birding expertise on binoculars ( for travelling and general purpose). However after going on here a few times I really like the idea of learning the names of the birds around me. Being able to turn the myriad of what I...

    Anyone tried using an ND filter on sunny days?

    I just took my shiny new Nikon Monarch 7 8x30 binoculars to the clifftop (thanks for those on the forum who helped with advice). It is overcast but bright today so you can't see where the sun is. When looking at a Kestrel on the clifftop I could see the bird really well but I found the bright...

    Is it exit pupil size that affects ease of alignment with eyes?

    I think this is definitely part of it. I notice that dropping the eye cups down one click from max and the shadowing becomes so severe it’s not usable. However I think I’m getting the hang of the placement. I tried them today in daylight and the FOV of the Monarch 7 blew all the others away (I...

    Is it exit pupil size that affects ease of alignment with eyes?

    Thanks for that. The weight of those is a bit high for me (690g) as I am trying to get the best £300 or less travel binocular so less than 500g is ideal 550g probably the max. However, I had a look at Opticron and noticed they make a model just like the monarch 7, the Opticron Traveller BGA ED...

    Is it exit pupil size that affects ease of alignment with eyes?

    Thanks for the help. I just tried the Monarch 7 8x30 again this evening and it was perfect. Absolutely amazing image. I'm not sure if the lower light helps or if I just got the alignment right this time with the IPD. Would evening light have helped (larger pupil size)? Or do you think the...

    Is it exit pupil size that affects ease of alignment with eyes?

    I have been trying out a few binoculars and with some even slight movements bring the black shadows over the sides/ top/middle etc of my view. Is it the exit pupil size that determines this? I.e the larger the objective the easier they stay in the sweet spot on your eyes? An example of a...

    Dielectric coating vs ED glass ?

    I am looking at binoculars in the £150-£200 range ish and I have found several models I like the look of where at the same price point they feature either : dielectric coatings or ED glass e.g Vortex Diamondback 8x32 = dielectric coating Celestron Trailseeker 8 x 32 = dielectric coating Hawke...

    A quick question about FOV and exit pupil size

    Thanks. Eeek, that does seem to be a high bar. That puts all 8x binoculars below 132M @ 1000M in the narrow category. That seems to be most of them.

    A quick question about FOV and exit pupil size

    Thats very useful thank you. Its a shame apparent field of view can't be calculated reliably. Do you know of a simple formula to calculate the apparent field of view, just to use as a guide? I'm making a spreadsheet of specs will be handy to add that number to use as a guide choosing which...

    A quick question about FOV and exit pupil size

    When looking through binoculars you only get a narrow circle surrounded by blackness to look through. What I want is for this circle to be as large as possible for a less claustrophobic viewing experience. Should I be looking at FOV (i.e Meters at 1000M) for this or the exit pupil size (in...
