Default Just Bought Scopetronics 80mm Spotting scope

Hi All,

I just bought the scopetronics 80mm spotting scope. Image sharpness are good however the colours are poor. Images are greenish (slightly less than the night vision green)

Tried tweaking in Photoshop but the colours are still un natural. Does polarisers help?

Anyone has this problem? Looking for pros to help me out.

Best regards
Rizal

Hi Rizal,

Unfortunately there isn't a lot you can do to correct the color tint. You can experiment with PhotoShop to try and kill some of the green tint, but spotting scopes which use this type coating or filtering just make it difficult to get correct colors. They are great for spotting scope purposes, but not really good for photography where you really want a neutral image without tinted correction.

Some of the best spotting scopes are designed with a tinted lens which cuts glare and sometimes helps with light gathering, but their intended purpose is not compatible with photography.


Best regards,

Lin

Hi Lin,

Thank for your reply. You're right. The photoshop tweaking doesn't help much.

The lens are ruby coated thus preventing the red channel to enter the scope and resulted in a greenish colour cast.

Do you know any filters to correct this problem.

Best regards
Rizal

Default HD or ED...

Unfortunately if we want to use the scopes in "digiscoping" I think we must "pay the price".
I mean, we must buy scopes with HD or ED lenses, treated to avoid the "chromatic aberration". Otherwise, with "simple" no treated lenses scopes (very good to watch birds but not for photography...) we get pictures with a blueish color around...
That may be what it happens to you.
Sorry to tell you that I don't know how you can solve your problem...
