    ATM 80 HD test report

    Hi all, During the last few months of silent Finnish birding season I have been very lucky to borrow and test a friend's latest Swarovski ATM80HD spotting scope with all the digiscoping bells and whistles. Squidge asked below about the opinions of this scope and to my slight surprise I couldn't...

    P5100 P, S, A or M?

    Hi all, I thought I would post some points on the relationships of the scope exit pupils, apertures and their effects on different exposure modes. I decided to separate it from the lengthy P5100 thread to make it easier to find... just in case someone happens to find this useful. Attached is a...

    Swing-out Baader

    Hi all, I just came up with an interesting "universal" swing-out adapter from Baader Planetarium. http://www.baader-planetarium.de/download/microstage_2.pdf It is relatively inexpensive, all metal construction which should hold up to 1 kg camera and it should fit on almost any eyepiece. It...

    Photos to aim for

    Hi all, http://www.luontokuva.org/default.asp?V_DOC_ID=2938 I wish some of these were mine (yeah, keep dreaming...) - anyway, here are some examples of what I would call success in bird/nature photography. What do you think? :t: Ilkka

    Digiscoping flying swallows

    Yeah right, not possible... that is what I thought until yesterday. But I wanted to test my new Panasonic FX01 and almost all the birds that I could find at the moment were either swifts or bank swallows. So, I attached the camera to the AT80HD (on a ball head) with a Baader Microstage, set the...

    Panasonic DMC-FX9 - Excellent!

    Hi all, I have made some side-by-side tests with the new Panasonic and my aging CP4500 and I have to say that I'm very impressed with the 6Mpix FX9. Yes, it is only a pocket-size, all-automatic point-and-shoot camera, but it does perform very well in digiscoping (inside a store ;)). + It has...

    Ideal focusing?

    Hi all, Focusing speed is one of the most significant ergonomical features of the binoculars. A user may love the optics, but may not be able to adapt to overly fast or slow focusing (and vice versa - of course). I seem to remember someone presenting an idea of dual focuser binoculars with two...

    Are the lemons just miscollimated cherries?

    Hi All, Unacceptable sample variation is said to exist even in most expensive optical products. Fortunately many of the top manufacturers dutifully repair or even replace clearly defective products. But how about those samples which are within acceptable tolerances, but noticeably (eg. in star...

    A versatile digiscoping adapter

    Hi, Just to let you know that a German astro product manufacturer Baader Planetarium has a new bracket-type digiscoping adapter, which fits to almost any scope/eyepiece-camera combinations (http://www.baader-planetarium.de/zubehoer/mechadap/digi-t2.htm). It seems to be designed mainly for...

    AT80 awful lens cover - but great service

    So I traded my Kowa TSN-823 to second hand Swaro AT80HD (to get those few mms more eye-relief). A fine scope indeed but the non elastic material makes the locking "nails" of the lens cap very fragile - both were fractured when I got the scope. I emailed the importer, described the problem and to...

    F-number & Depth of field

    Hi all, The term "depth of field" is commonly used in birding optics, but I have found it quite hard to understand what it actually means in binoculars (or scopes), which cannot be "stopped down". Why do some binoculars/scopes with similar power and objective diameter have more depth of field...

    Nikon HG & digiscoping

    Hi, I wanted to demonstrate the chromatic aberration of Nikon HG binoculars with my digital camera and to my surprise I found out that these binos perform *very* well in digiscoping. Sorry if this is too obvious, but I'll post this anyway just in case some HG owners have not found this...

    Focusing direction

    I was wondering if anybody has paid attention on the direction of focusing when choosing binoculars (or a scope)? I am very right handed and when I want to focus rapidly (usually to follow an escaping bird) to me it is more natural to pull the focus ring with right hand fingers (clockwise: close...

    Telescope comparison

    Hi All, I just noticed that a Finnish digiscoping pioneer Arto Juvonen has made a very useful comparison of the most common digiscope-setups. The camera was Coolpix 4500 and the adapter made by Fotofennica (= Spidertech ?). The tested scopes were from Swaro, Leica, Nikon, Opticron, Zeiss and...

    Greetings from Finland

    Hello Forum, Seldom (...actually never) have I seen so many netizens discussing about a passionate hobby with such friendliness, politeness and sense of humour. Bird Forum was like a breath of fresh air after having just read some computing threads full of flame. I just felt I had to jump in...
