Your considerations for selection of good spotting scopes
When you are trying to select spotting scopes that would suit both your requirements and budget you require taking a number of aspects into consideration. The first consideration is the size. It is the size of the lens that determinations the capability to gather lights for viewing. If you are on budget and wish to buy small or medium size spotting scopes, you can select one that has large objective lens. The brightness of the lens will make good the loss of optical qualities if any. The only problem would be that the weight of the scope will be higher with larger lens. Best serving scopes come in the size of 60 to 85 mm normally.
Magnification is a very important aspect of the spotting scope or rifle scopes. Most of the spotting scopes have interchangeable eyepiece and each of them is set to specific zoom magnification. Eyepiece that is single power always gives better image compared to the zoom eyepieces. Due to this reason most of the people buy single eyepiece for spotting the birds. On the other hand when you require your scope for digi-scoping the shots taken with the single powered eyepiece would be far superior to the photos taken through the zoom.
The most important factor is the efficiency of your lens. For this most of the people to day use fluorite or ED glass for their Binoculars or the scopes. Especially in low light conditions these glasses give much better results.
