Hi all, can anyone advise please: a) where in this camera a sodium vapour filter could be installed b) where such a filter could be obtained Many thanks! - Balt
Balt, A filter like this would need to be placed over the lens. http://www.lumicon.com/store/p/40-2-Deep-Sky-Telescope-Filter.aspx
http://www.cloudynights.com/page/ar...yglow-broad-band-light-pollution-filter-r2316 The above article is 5 years old but explains a lot. Below is another example filter. http://www.optcorp.com/filters/all-...light-pollution-filter-ccd-2inch-mounted.html Regards Tim
Thanks Tim, useful pointers! I'm not with the camera at the moment, does a 2" thread fit over the lens? Or will we need to rig something? Thanks - Balt
Balt, I will pull the drawings tonight or in the morning. Will let you know. They do make step-up and step-down rings for filters regardless.
