For sale is an SVBony 7nm OIII 2 inch filter
https://www.svbony.com/2-inch-svbony...-space-filter/
I now have a 3nm OIII filter and therefore don’t use the 7 nm filter at all.
In excellent as new condition- hardly used. I’m sorry I don’t have the cardboard box in which it came.
I have attached an unstretched stack from AstroPixel Processor- converted to jpg - This filter is a pretty good copy IMHO
Thanks for looking PM if interested.
Looking for $ 165 pickup in Sydney or $ 175 posted anywhere in Australia
