Hi Dazz, Hang in there, I live in the West Midlands and suffer bad light pollution, I used M1 as a test on sky transparency - some nights it was there and others - not, try covering your head with a "cloak" whilst at the eyepiece to really darken your viewing - sounds and looks daft - but try it - it works.

Get used to the filter and try and use it for a while, then have another look at M1, also if your using GOTO and slew to M1, look around with the direction buttons on the handset - it may be just out of the FOV.

Also try to observe with no Moon in the sky, if still no luck, experiment with the magnification your using - I know that these objects should be viewed with a low power - try increasing the power a little - this also helps to darken the background sky helping with contrast.

Stick in there Dazz and try looking for the galaxies/nebulae between mag 9 and 10 - no fainter to start with, also planetary nebula "look" a lot brighter than there mag suggests (being more compact and not spread out across the sky), try the one in Draco for starters - really bright.

Sky contrast changes from night to night - some nights better than others - Take care and regards Paul.

A UHC filter works a little better for M1 than an OIII. An OIII should help a little, however. This is a rather faint and difficult object. Try M42 for your first Nebula.
