Or is my postion (sky darkness etc) not enough with my scope to make it possible to capture the Flame, let alone the horsehead. Last night I think was about as good as I'll get. OR... is that fact that it was visible at all a good sign that with the right eyepeices and filters I might see them?

I have another problem translating the info as well,... I don't know what the focal lenghth of my scope is. I can't find it anywhere in the book I got with it. Is there a way of calculating it?

Thanks
Michelle
Hi Michelle, the Flame Nebula being anywhere else in the sky on it's own would be a show piece, but unfortunatly it sits right next to Alnitak which is many more magnitudes brighter,so the glare just kills it
What make of telescope do you have?
I think the common 10" scopes are F4.8 or there abouts.
See Here for the way a way to calculate your focal length
I can assure you your scope is plenty Big enough to see the Horse Head and other Dark Nebulae, it will just require you to gain some experience with observing before you can get down to seeing these faint objects
Cheers
