Is this a diffucult object to see?

From a reasonably dark site, a 15X70 bino readily reveals the halo of light surrounding the star. Similar brightness stars in the area serve as a comparison, for which there is no similar surrounding fuzz.

NGC 7023 TV 102 Antennas S=6, T=7 14mm 7 stars and faint, pretty large nebulosity, not much, averted vision makes it more prominent.
Hope that helps;

It takes more of a dark and transparent sky versus aperture. It was our October 2012 Observer's Challenge and the range of scopes that spotted it proved as much.

My 12" f/5 dob with a 17mm Nagler produced a very fine view. The central star appears fuzzy and different than all other stars around it. The skies of southeastern Arizona are dark and very transparent. These two traits allowed me to see a fair bit of detail. There was an obvious dark stripe through the nebulosity.
When the power was bumped up with the 9mm Nagler more subtle dark regions became visible. Mottling in the nebula around the star were obvious.
Given that this is a reflection nebula I didn't try any nebula filters.
Very clear and very dark skies are key to getting every bit of detail out of this target.

It's not at all difficult from a dark sky, but it's a reflection nebula, so it doesn't respond well to a light pollution filter at all. Under a mag 6 sky, it's unmistakable in a 60mm...
This is not necessarily true. NGC 7023 is primarily a reflection nebula, and as such, it can often be helped at least to a mild degree by the use of a broad-band LPR filter like the Lumicon Deep-sky or Orion Skyglow. The improvement of the view is mild, but it is there. It is best seen under skies that are already at least moderately dark, as under heavier skyglow, the broad-band filters don't work nearly as well. Indeed, the outer faint loops around the central mass are definitely easier to see with the broad-band filters than without them. Clear skies to you.

I had a very nice look at NGC 7023 with my 20" last Tuesday evening (Oct 8)about an hour after the Moon set. It was spectacular to say the least. It actually wasn't the highlight of the evening though because I was using it as a starting point of a star hop to Gyulbudaghian's Nebula. http://observing.sky...ct/GM_1-29.html Right now it's experiencing a brightening so Marcus you should give that a try also. Wait until the night has good transparency for both.

I think the moon was present indeed. I'll try for it again on a moonless night.
