thanks Gary, Andrew and Marc.
i had a go at re-processing M42 and masking the core area, i dont know if i've overdone it or not but i guess you guys will soon let me know
i havent done any masking in photoshop before so it didnt really work how id hoped but its better than nothing i guess
i'm happy with the tarantula shot for now, its got to be my deepest shot yet
