Hi folks~

I've posted on another forum here on Cloudy w this question...

a few answers ...suggesting its for 

astrophotography uses .... 7nm??

....but I'm wishing for more input to be better informed.

 

>I"m Still ... trying to exactly ID this filter I bought on a scope deal.

 

Orion made~

The only markings on it:  " Korea   Orion H-ALPHA filter "

 

As I'm going to sell it ...( I've NO solar gear, nor plans to image .. I only do visual observing ..)

...Does ANYone out there have a clue about this filter/specs etc.???

 

I still CANNOT find this exact filter anywhere on the net. Yet, its printing is for certain our

well-known 'Orion Telescopes and Binoculars' company USA ... ( not the UK Orion ive seen ads for )

 

Thoughts please~

 

thx,

Alexander
