An order was placed with a mechanic for an adaptor to be made for my Nikon V1's 10-30mm zoom lens with a view to hooking it onto my Swarovski 80 HD STM for digiscoping purposes. The adaptor was collected this evening.

The connection was done tonight using two connectors. In the following shots, you can see the two of them: the black one that is attached to the eyepiece of the fieldscope; and the silver one that is attached to the 10-30mm zoom lens of the Nikon V1. They were join screwed together to form into an amalgamated piece.

When the 30x- and 45x-eyepieces are used, vignet-free conditions are possible from the focal length of 11.5mm onward to the telephotographic end of the 10-30mm zoom len.

請問如何用眼透過目鏡直接看景物。

Re:請問如何用眼透過目鏡直接看景物?

Just look into the viewfinder of the camera, you will be able to see things captured by the fieldscope.
You PROBABLY are not asking for such an answer. So, please explain a little bit more what your queries are. Maybe, I can help further.

多謝你的回答。
我想問是如何不透過觀景器或 LCD 看景物,怎樣可直接看光學影像。
我覺得光學影像最美。

Dear Mr Chung,
In digiscoping, the fieldscope is the primary source from which an image comes. The image is pretty small and it takes the eyepiece to magnify it to be visible. The image then passes through the lens of the compact digital camera and is captured by the sensor which converts it to digital. The image in the viewfinder of the camera is only a replica of the digital image captured and is, as you said, not an optical image.
You are right that the image itself is incomparable with the one we see directly from a lens. Two reasons for that: (i) the source of light captured by the digital camera through which we see the digital image is secondary; and ii) the resolution of the electronic viewfinder is, thus far, still not that good. There is still big room for improvement to regenerate a virtual image that exactly resembles the original object itself.
In fact, despite the fact that we view the object captured from the digiscope using, for example, a digital single lens reflex camera, the image we see is beyond compare with the one we see in cameras coupled with a zoom or prime lens. That is because the aperture of the fieldscope is very small, usually around f10. The light through the f10 aperture is too dim to enable a clear image to form. But still, the image is good enough for focusing purposes.
Along this line of thinking, digiscoping is just a makeshift measure in avian photography. Digiscoping is more suitable for avian photography of birds that are relative less active.
Happy shooting.
Regards,
Pete

Nikon V1 + 10-30mm Zoom Lens + Swarovski 80 HD STM and 30x-eyepiece.
Jan 20, 01, 2012am.
Some information for reference:
1.  ISO 100 for the heron and common kingfisher shots and 200 for the white-breasted.
2.  Shutter release using Nikon's wireless controller ML-L3. Real-time release is capable with V1 this time as compared to the one in, for example, Nikon CP8400, where a time lap of 2 sec exists. A real fun with such an enhancement.
3. Manual zooming is another big fun with V1, not only saving electricity but also enhancing the swiftness and pinpoint accuracy of framing.
4. I have not tried shooting at a higher ISO but at 200, noises are minimal. I think at 400, V1 stands a good chance to provide decent images with little noises.
5. Focusing is fast and accurate, a performance, in my opinion, renowned in almost all the Nikon's cameras I have used, namely D700, D200, CP8400, P5100.
6. White balance control is appealing.
7. The RAW file is not openable in my version of PhotoShop, the CS4. The same also happens with the version of NX2 I have. I use the accompanying software of the kit set to open the file, retouch images and convert them to the tif 16-bit files for further processing in my CS4.

Re. 7, would be grateful if forum members share the version of PS and NX2 that can directly open and retouch the V1 raw files.

Here are a few images for sharing purposes. A word about the weather for today: dull and overcast with occasional drizzles.

1.  The closer, the better; a golden rule in digiscoping. It does away the effect from the particulate matters in the air.

This time, a 45x-eyepiece has been used.
Had a short trip to The Chinese University of Hong Kong this afternoon to see how the adaptor for the Nikon V1 performed on my digiscoping setup.
Superb is the word I would like to say for the adaptor. Thanks to Mechanic Chan for his input to lick the adaptor into shape.

Here is a shot from today's fieldtrip. ISO set at 200.

Great adapter and great mechanic workmanship.

Mechanic Chan should do something about digiscoping himself, so I think about it.
He definitely will be able to make even greater adaptors for coupling compact digital cameras with the eyepiece. Chan was once frenetic about photography; as can be seen from the 500mm East Germany lens that was laid idling on a desk in his workshop. I always encouraged him to kind of 'jump in' and make some dream gear that he thinks are the best for digiscoping purpsoes. He just smiled and then said, hm, I will think about it. I hope he will some day for we must benefit from what he makes for himself if he sets out to digiscope.
Thanks for popping by and giving comments.

Weather still as gloomy as the economy in the US and Europe. Very slow shutter speeds had to be used today to capture the birds in the following shots. ISO 200 was used.
Love the performance of the V1 as a digiscoping gear.
Here are a few shots from today's short trip to The Chinese University of Hong Kong in the afternoon.

Some common kingfisher shots from Shing Mun Valley Park taken with Swarovski's 80 HD STM, 30x-eyepiece and Nikon's V1 and 10-30mm zoom lens.
The ISO is set at 100 and the shots were taken this morning. The shutter was released with the remote control unit, the ML-L3.
