    Olympus OM-D M5 with Kowa 884

    How are you getting on? Hello, I have a Kowa TSN 883 also and am looking to move up from phonescoping to something more proffessional - I wanted to ask you how you're getting on with your purchase and if you are still happy with it?

    Best digiscoping camera?

    I've been using a Kowa 883 and Samsung S5 for digiscoping. Sometimes I get amazing photos but frequently I'm underwhelmed - things get dark and noisy with magnification. I suspect the phone might be the limiting factor rather than the scope. I keep reading that RAW files are a good idea too...

    New Viking 8x42 ED FF w fieldflatteners

    I have not tried the prime ED but I went binocular shopping with another proffessional ornithologist today and he picked out the 8x42 ED FFs. I would not argue with that; little different from Leicas at twice the price and superior (IMO) to some Zeiss Terras (*the cheaper Chinese licensed Zeiss...

    Nikon 7x50 oceanpro compass

    Hi there, if you're looking for something higher power with a compass you could be struggling; it seems that compasses are generally only found in 7x binoculars or lower because their user are predominantly sailors who prefer 7x because it's hard to stabilise higher magnifications sufficiently...

    Compass and Reticule Binoculars for vantage point surveys

    Hi Guys, thanks for the continued suggestions! :) Binastro - I enjoyed the Tornado story but the debunking supplied by Mono was very intersting too! As for computerised mounts - sounds awesome. It had crossed my mind before as I have considered getting a GOTO mount and doing a bit of...

    Compass and Reticule Binoculars for vantage point surveys

    Hi Guys, thanks for your further comments! I'll reply in turn: James - It's interesting to hear from someone doing the same kind of work in Canada and I see that you are tracking the same taxa of birds as we do in the UK. We also work according to height bands although there is some variation...

    Compass and Reticule Binoculars for vantage point surveys

    That's terrible - was your benefactor able to get their money back for your water logged present? I thought marine binoculars were genuinely waterproof.

    Compass and Reticule Binoculars for vantage point surveys

    Hi Chris! I'm really pleased that approach worked for you and have been thinking along fairly similar lines. I recently took a series of panoramic photos of my vantage points. I decided to make line drawings of them as I was also thinking of printing them out but wanted to save print costs...

    Compass and Reticule Binoculars for vantage point surveys

    Thanks very much for your ideas everyone! Im kind of tired so I haven't done all the reading and looking I'd like to yet to but, in the interim I can say: Hi David !(typo) - I like your thinking! This stuff sounds good and geeky, I wish I had the know how to take it on. I see that the...

    Compass and Reticule Binoculars for vantage point surveys

    Wow, that was fast! Thanks for replying! I know what you mean about compasses getting stuck. I was wondering about digital compasses and if they can cope with higher elevations. Where the Steiner and Nikon ones you were suggesting digital or 'traditional' in design? I see no reason why in...

    Porro or Roof ? Your choice.

    Whatever the arguments about 3D effect and ergonomic it's important to remember that porros typically have fewer optical surfaces over which light can be reflected and lost or (worse still) bounced back to create haze. Porro prisms rely on total internal reflection in their prisms so don't...

    Vantage Point Survey methods

    Hi Folks, My name is Andy Francis, I do surveys for environmental impact assessment for wind farms. Part of the job requires plotting flight lines of birds on maps and estimating their heights at 15 second intervals. In essence this is very simple but when you think about it it's actually 3D...
