Hi mate ok just been looking at a 685 nm 2 inch ir pass filter on amazon it does however say its for planetary photos moon etc .
Will this do for dso as well and also will it help with moon glare when it's up when i image dso or do I need a different wavelength I already have some ir filters for landscapes etc but they are at the 720 850 and 900 nm and I think this would only get bw at this higher end
This is the link to the one I'm looking at
