MAX,
Let me first assure you that the Baader adapter does not affect the optics of the camera/scope at all - it just keeps the two together at the desired distance. IMO the only problem with the Baader-bracket is that it is a little clumsy and may look bulky on your compact and pretty scope. The combination giving "poor results" would require a little more analysis
1. Maybe the most common complaint about poor image quality comes when one tries to photograph a distant object by zooming in with both the camera and the scope. This is especially risky with a 62/65mm scope. The small Leica works very well at 14x-20x powers, but pushing above that will increase shake, atmospheric disturbances etc. The closer the target and the more light the better.
2. The Leica eyepieces have very long eye-relief (A Good Thing™) and the Canon A95 requires relatively little ER (also A Good Thing™). These together mean that you can easily bring the camera too close to the scope and there may appear mysterious black shadows in the camera (the same "blackout-problem" as some have with their binoculars). You just have to make sure that the camera is far enough from the scope: the edges of the field of view must be sharp.
3. Some people may be tempted to attach totally unsuitable cameras onto the adapter brackets with large camera platform - just because they can. Unfortunately those ultra long "super-zoom" cameras are not good for digiscoping.
The Leica APO and the Canon A95 are excellent digiscoping partners. Baader adapter surely works with them as long as you find the correct distance between them and don't try to exceed their optical limits.
The other - more compact - option is to use tube adapters: you need a filter adapter (eg.
http://www.lensmateonline.com/A80adapter.htm) and a step-down ring (52mm to 28mm). This way you can use any of the Coolpix 4500 compatible adapters. One very good tube adapter for angled scopes is made by Spidertech (

Hope this helps, :t:
