FAQ

Q1 Which is better--to zoom in with the camera or use a higher magnification eyepiece to get a nicer magnified image?

A1 From the point of view of quality, using a higher-magnification eyepiece would be better. If you zoom in with the camera, considering image quality and the ease of focusing, wide angles to mid-range zoom positions are easiest to use.

Q2 The green AF indicator does not light up,
and I cannot get the image in focus.

A2 Because you are taking supertelephoto shots that the camera alone was not designed for, there will be situations where the camera's autofocus system is unable to focus. If, despite repeating steps one to two in the section " How to take a picture "the green AF lamp does not light up, you may get good results by pressing the shutter-release button halfway while looking at the camera's monitor and adjusting the focus until the image appears sharp, then taking the picture with the cable release. Using this operation, you take the picture even when the AF indicator light is blinking red.

Q3 Pictures come out blurred.

A3 Causes for this could be subject movement or camera shake, or the camera could be focusing on something other than the subject. There is a possibility that the equipment may shake when you take the picture, or the subject may be moving. Set the equipment up securely, and slowly and carefully release the shutter with the cable release, ensuring that blur does not result from equipment shake or hand movement. There is nothing you can do about subject movement, so you can get good results by quickly framing the shot and taking plenty of pictures using the continuous shooting function. If the camera is focusing on something other than the subject, use the camera's AF Lock or AF Area selection to set the focus on the subject.

Q4 I have trouble taking pictures of distant subjects.

A4 The specific distance will depend on actual shooting conditions, but you can take clear pictures of subjects up to about 25 meters away. With subjects further away than 25 meters, it might be best to take photos for record purposes only.

Q5 Can any compact digital camera be used?

A5 You can connect some Nikon COOLPIX series cameras. For details, please check catalogues or the product information pages.

Q6 Is digiscoping possible with older models of
Fieldscopes and eyepieces?

A6 Depending on the type of Fieldscope and the shape of the eyepiece, it may be possible to connect them to cameras using attachments. However, when you connect MC eyepieces to a camera using attachments, unlike DS eyepieces, vignetting will occur unless you only use the camera's zoom function or you use the longest telephoto. This means that the chance of taking good pictures is lower, so this solution is not recommended.

How to distinguish between different models: Fieldscopes with a 60 mm objective lens diameter were the first generation I series, followed by the II series and the current III series. The model name is not recorded on the Fieldscope body, so please refer to Figure 1. In relation to connections for digiscoping, II series and III series models are absolutely identical, but the I series has dustproofing at the connection with the eyepiece, and there is only one eyepiece that can be connected. Please see Figure 1.

How to recognize ED lens types: ED lens types can be distinguished by:
- the letters ED on the Nikon emblem; and
- the red line around the outer circumference of the objective lens.
The exception is that with I series scopes, there is no ED lettering on the Nikon emblem, but gold lettering indicates that it is the ED type.

How to distinguish eyepieces: The shape of the observation end (Figure 2) is the key. When attaching to the older eyepieces, if the observation end is a turn and slide form, it is possible to attach using the FSA-1 and FSA-2 Digital Camera Attachments (except for the 20-60x / 25-75x MC Zoom). Eyepieces with a soft rubber eye cup do not accept the FSA-1 and FSA-2 Digital Camera Attachments, so they cannot be connected to digiscoping equipment.
Please see Figure 2.
