Digiscoping: File Saving (Updated 2017)

File Saving: I’ll save several versions of every processed image.

1) Original image out of the camera – 6000x4000 gives a 24MPx image that takes up ~35Mb – do not alter!


2) If I plan to print an image I'll save it as a TIFF. This may make the image get as large as 144Mb! but it will look great on photo paper.


3) If I plan to post an image to my blog then I'll downsize the processed image to 2048 pixels on the long side. This will give an image that looks nice on even the largest monitors. I'll sometimes add a touch of Unsharpening (Amount=50%, Radius=0.5, Threshold=0) and save as a JPG  with no compression.

Hi,Jerry,
I am keen to try out digiscoping and would like to seek your advice on a no. of matters:

1.Which camera shoule I use? I am currently using Nikon D7100, should I use it for digiscoping, or should I get Nikon V1 which is higly recommended for digiscoping?

2.If I should use Nikon V1, whether I should use it with a lens (e.g. a 18.5mm lens) and connect it to the eyepiece by an adapter, say DCB II from Swaroski, or should I just connect the body without the lens to the eyepiece by say TLS APo from Swarovski? Which one produce better results in terms of picture quality and ease of use?

3. If I should connect the camera body only without the lens, dose that mean that I cannot use auto-focus and A-mode for metering?

4. On the choice of spotting scope, I am thinking of the STX model from Swarovski. Any advice on this and should I get 85mm or 95mm?

5. How about spotting scopes from Nikon, such as the EDG VR model, would it work better with Nikon cameras, such as V1 or D7100?

Look forward to hearing your expert advice!

Best regards,
Ivan Chan
