last Sunday, I took this picture of a buzzard near Cologne in Germany.
When it flew up to the branch it sits on in the picture, I noticed that the tail was a very warm brown. So I set up scope while the buzzard patiently waited, keeping an eye on me all the time :-)
I just observed a Motacilla flava ssp. on Germany's North Sea coast which to my untrained eye looked like a perfect example of a M. f. flavissima male in breeding plumage.
I was told (by the very friendly local ornitho.de expert) that in autumn, it's very difficult to reliably...
After designing a couple of different solutions for mounting a reflex sight on a (Kowa 883) spotting scope, I've tried something new now and decided to create a mount that is part of the quick release plate rather than mounted directly to the scope.
The challenge with designing a...
New adapter design to mount a "red dot" (reflector/reflex) sight to a spotting scope
Here's a new 3D-printable adapter design to mount a "red dot" (reflector/reflex) sight to a spotting scope:
As pictured, it fits a Kowa 883. Mounting works by means of a 4 mm bungee cord with...
I recently saw a nest here in North Germany, near Lauenburg, I couldn't identify: It was built in a boat shed on the foundation of what clearly had been a Barn Swallow nest, but it had "walls" of still fairly green grass or small leaves/leaf parts going up all the way to the roof...
I wonder if my identification "Honey Buzzard" is correct for this bird:
Somehow, I never manage to get a good close-up view of Honey Buzzards ... whenever I see them, they are circling high up in the thermals, like this one.
Here's a list of the breeding succeses of White Storks in one particular nest in Northern Germany.
The nest is situated on top of a purpose-built concrete pole in the large garden of a farmhouse in Northern Germany. A wetland nature reserve is nearby.
The nest was installed in...
Fresnel Lens to put Smartphone Screen at "Infinity"? (Birding without Multifocals)
Just a quick thought: Has anyone ever tried to put a Fresnel lens in front of a smartphone screen to put it at optical infinity?
My idea is to work around the need to use multifocals to access the...
After seeing an adult Northern Gannet in the Kattegat just south of Tunø yesterday, I wonder ... how frequent are Northern Gannets in the Kattegat and in the (rest of) the Baltic Sea?
Opus indicates that there have been records of Gannets in most countries on the south coast of...
I just created a 3D-printed adapter to mount action cameras to bincoulars:
This relies on the binoculars having a 1/4" thread in the hinge, and the action camera being compatible with a NATO/Picatinny rail.
The adapter is customizable and can be downloaded here...
What tools do you use to tighten the typical 1/4" tripod screws with slotted head?
The slot is too wide to be of much use with the screwdrivers I have, and while in some cases, coins can be used with good effect, I have other applications where something more screwdriver-shaped...
Based on an idea suggested by another community member, and using the measurements he took of his Swarovski scope, I just created and uploaded a 3D printable red dot/reflex sight adapter for the ATS 65.
Photographs of the adapter he printed, installed on his scope:
I'm looking for the proper measurements of the common "video" style mounting plate as used by many quick release plates, as the one in this shot:
Basically, the two defining measurements I'm looking for are:
- Diameter of "anti-rotation" lug (apparently 4 to 5 mm?)
I'd appreciate your help with the identification of the harrier on the photos I posted in this thread:
(I guess it would have been more appropriate to post it here right away, but that only occurred to me when I had already posted in the...
Last Sunday, I visited the Kirchwerder Wiesen and spotted this harrier:
I'm not quite sure of the ID ... it looks very much like a male Marsh Harrier in most respects, but the dark upper parts that look black and grey really confused me.
I'll admit that from some angles, the...
Not a directly photography related question, but maybe you could help me anyway: Is there an overview over astro dovetail standards to be found online, somewhere?
My fascination with reflex sights (red dot finders) has induced me to design a dovetail-to-NATO-rail adapter for my...
I'm looking for the eye relief (... distance) of the Leica 25 x – 50 x WW ASPH eyepiece (when used with the Leica 65 APO Televid).
Somehow, this information is nowhere to be found on the Leica website.
(I actually found the sales brochure with the "eyepiece table" referenced by...
In the recent thread "Straight or Angled", Etudiant mentioned the advantages of using a shoulder stock to stabilize the view through a hand-held scope.
Intrigued by the idea and aided by Sancho's feedback on his experience with...
I just stumbled upon Piergiovanni's article on using the TSN-883 for astronomic observation:
Though I don't understand Italian, I believe the article contains a recommendation for the scope owner...
Since Kowa doesn't offer a digiscoping adapter for my specific smartphone type, I had a go at filling the gap by 3D-printing an adapter of my own design.
This is what it looks like:
I preferred this over a universal adapter because universals are usually quite expensive, have...
After trying a red dot sight (also known as reflex or reflector sight) on my Nikon ED50A both from a tripod and when held in the hand, I'm pretty enthusiastic about the technology!
Here is a picture of my test rig. It combines a "flash grip" mounted between tripod and scope base...
