Tough alright!
Had a go tonight with my 10" f/4.9. It lies directly over the city from my place. Only spotted with a 15mm EP and a nebula filter. Just. Not good seeing either. Even M42 was far below par.
Not a problem with my 17.5" from home. Too easy with such grunt.
Intrigueing to think that Messier spotted this one and missed much brighter objects in forming his first catalogue.
