Hi,

I'm in a Bortle 8 situation, with massive sodium lights from a major railway yard lighting up the sky, and am around 1.5 kilometres from the centre of a city of 250,000 people :-(

 

My scope is a CPC925, wedge mounted with f6.3 reducer - it works well and guides accurately. No problem getting round stars at any exposure length. My camera is an ASI 533MC Pro

 

I would like recommendations for a light pollution filter for galaxy imaging. I have an Optolong L Extreme on order for nebs - previously had an L Enhance, but decided to "upgrade". I also have an old Idas LPS P1, but this has not been good enough to cut through the light pollution. Is there any other that would assist?

 

TIA

Gary
