Subject: Protective filter for scope [Print This Page]

Author: jojomau Time: 30/09/2010 17:04 Subject: Protective filter for scope

I am new around and I have just acquired a scope. Please advise if I should have a protective filter installed on the scope to protect the front element. I intend to do some digiscoping with the scope.

It's long struck me as a bit odd that scopes don't even have a thread to mount a purely protective filter, which could be changed when scratching occurs, as it inevitably will.

Maybe some do but I don't think my 3 or 4 year old Swarowski does.

I just bought a Swarovski STS 80 HD which accepts a 82mm filter. I just wonder what birders do, in particular those who have great experiences with digiscoping. Specifically, I am worrying if an installed filter would result in vignetting. A quality 82mm filter is not cheap, well for me.

Please advise.

我從來無諗過係單筒加 filter，我覺得無呢個需要

我没有在单筒前加滤镜，平时都是拉出遮光罩的。

Thanks to Kitty for positive response and the effort of posting references for me.

Thanks to other inputs as well. Now I realize there are some scopes with no filter thread and some birders are very confident in handling their equipment.
