Long wavelengths are less effected by atmospheric turbulence. You will find most large aperture imagers are using something in the 610~850nm range of red to infrared wavelengths to help steady the seeing conditions for high resolution imaging. The longer wavelengths have lower angular resolution than shorter wavelengths, but they are again less effected by atmospheric turbulence so allow a larger aperture to have calmer seeing conditions to image in, then lucky imaging does the rest (ideally with a monochrome sensor). If you want higher angular resolution for the same aperture, one can image with a shorter wavelength such as 500nm (green) or even shorter, however, this is not common with larger apertures because they are heavily affected by atmospheric turbulence and so require a lot better seeing conditions. Shorter wavengths like this are useful to get the most out of smaller aperture instruments under ok seeing conditions, such as something up to 150mm aperture, and all the smaller apertures below that, if seeing allows, a 500nm green filter would be useful to squeeze out more angular resolution for the aperture's limits, provided you block the IR wavelengths with it. As you go to 150mm or larger apertures, 200mm, 300mm, or larger, virtually no one uses short wavelength because the seeing conditions do not support the aperture, so with larger aperture, again, you'll find long red to infrared wavelength filters being used, with a monochrome sensor, such as 610nm Red, 685nm red-near infrared, 742nm infrared (very popular) and upwards of 850nm infrared. Again, the longer wavelengths have lower angular resolution, but with calmer seeing conditions and a big aperture scope, one can image higher resolution lunar surface images.
I use a Baader 610nm Red Longpass filter and Proplanet 742nm IR filter with a monochrome sensor (ASI290MM & ASI174MM) with my 200mm and larger aperture instruments for lunar imaging. For full disc lunar imaging with smaller apertures (80mm to 120mm) I tend to use a Baader 500nm Green filter with a UV/IR block filter and the same monochrome sensors, to get the higher angular resolution of the shorter wavelength.
