Fuji F31fd
In response to Neil's previous forum re the same subject, the Fuji F31 is very good under dim light condition. The following, Grey Heron, was taken on 23.1.2007 at Tsim Bui Tsui when the sun went down (5.45pm), dc setting was ISO800.

I think a sub-topic forum for 'digiscoping' could be setup because more and more discussion are posted.

Can anyone tell me why I can not attach a photo in the forum? I could do it previously.

Solved problem. File attached. Thanks Forrest.

Hand held
waterblowing,
You did it just handheld ? Pentax is very good taking into consideration its price.

Tried out custom made adaptor
Gear:
Carl Zeiss 65T-FL
23X eye piece
Fuji F31Fd
All pictures taken toady on 22/4/07 in Long Valley before it rained heavily.
All cropped to 1600 x1200 than downsized to 800 x 600
Neat-image and Photoshop processed
I think the small 65mm scope really performs less well with the large 80 or 85mm scope
cwchan 23/04/2007 14:14
Alexander,
I agree the 65mm objective is the main reason that the picture quality is not as good as the scopes equipped with 80mm objectives. However, you can improve the sharpness if you step down the aperture to f5.6 or f8. :lol:
Can you share with us how your adaptor looks like?

From my experience with Swarovski you would be better using a longer scope eyepiece and less zoom on the camera. Most digicam lenses are'nt at their best near full zoom and the lack of light ( due to high f stop ) makes auto focusing difficult. I don't like to zoom the camera lens over half way unless the light is very good and the subject is close. Neil.

My way to custom-made adaptor is to find adaptor rings with inner diameter that match the eyepiece and the camera lens, then linked them up
For Fuji31fd, the diameter of the lens is 30.5mm
I found out that 34mm male filter ring have inner diameter of 30.5mm, which after a bit more polishing, fit sluggly to the Fuji31fd lens
The outer diameter of the 23/30x eyepiece and the 30/40x Zeiss eyepiece is 49mm. Usually a 52mm male filter will fit. And I am lucky to find an old lens hood that again fit sluggly to the rubber.
All the materials were found in 2nd hand camera shops near and around Chan Hung Camera in TST. It costs me less than $200 and these pieces are "modular"!

some more photos.
cwchan 24/04/2007 21:28
Thanks Uncle Tall,
It is simple and effective :lol: .
However, you can not zoom after placing the adaptor to your DC. Do you use cable release to activate the shutter which is very important to reduce vibration? If don't, think about it.

I stayed until after dusk last Wednesday and still wanted to keep digiscoping the Curlew Sandpipers so I switched from the Nikon 8400 to the Fuji F31fd and set kept shooting from iso 800 to 1600 to 3200. Here is the 1600 and 3200 images taken at 60x on the zoom eyepiece. Neil.

Neil,
Nice shot despite at such high ISO. :lol:
I don't think 8400 can give such good result.

The F31 is still my backup DC . I use it occasionally, just like today. The picture quality is very good.
