Red filter for imaging
Happy festive season to all!
I am looking for a red /deep red filter for imaging the moon to try to partly compensate for the predominently below average seeing at my place. Online, at our local astro shops, I have been able to find a red one as part of a LRGB set, but not individually. Can an imaging red filter be bought individually? If it can, what would be a good one? I would be very grateful if someone could point me in the right direction.
If you could tell me a good palce where I could get a cooling fan for a SW 10" dobs, it would be great too!
