The Cone Nebula, yes.




The Cone Nebula is a true challenge object. It's far more difficult than B33.

The only time that I've been able to catch a glimpse of it was through a 30" Tectron Dob at New Mexico Skies (magnitude 7 skies at an altitude of 7,000 feet).

I have seen the Cone a couple of times in my 10 inch Newtonian with a narrow-band nebula filter, but that was on a few exceptional nights. Like the Horsehead, its visibility is highly dependent on conditions. I did see it without a filter in my 14 inch f/4.6 Newtonian one night last winter, but it was very vague and the filtered view was a bit better. This is one object where the H-beta filter proved useful, although it was still a little easier in my DGM Optics NPB filter. Clear skies to you.

It's still M1 for me.
