I'm gonna tackle this with my 10" Classic and a OIII filter tonight,probably gonna be tough going,anyone have any luck with a similar setup? The stars are aligned with me for clear viewing(although humidity might be in play but got a dew heater for that lol). I'm really priming myself for a nice viewing of Jupiter since I love watching it and nebulas and galaxies after that(clusters,bah)

Saw this object, NGC 7635 in Cas with a 10" SCT @96x. Object is dim, a dim patch of light with an even dimmer arc stretching from it. Using a narrowband filter the arc extends further outward. Note that I was not a very experienced observer when I saw this; should go re view this object now that I have a darker site and better EPs. You should be able to see "parts" of it in your 10".

I saw the bubble very faintly for the first time back in 1998 with an 8" dob and a narrowband filter, from a backyard with a limiting magnitude of about 5.5. OIII will work pretty well on it, and you've got a 10" scope, so so long as you have decently dark skies, you should see it. With my 8", all it looked like was a faint, featureless glow around an 8th magnitude star.

The bubble thru a 6th mag v sky was a little funny in my 8".
There were two 8th magnitude-ish stars - one had a slight haze around it the other didnt. That was the extent of my bubble.

I observed the Bubble nebula (NGC 7635) with my old 10 inch. At 129X with an OIII filter, this object covered a 14' by 4' area and was aligned northwest to southeast. The nebulosity appeared brightest around 8.7 magnitude SAO 20575 near the southeast end of the nebulosity.
7.0 magnitude HD 220057 lies 6' southwest of the Bubble nebula. Here's a link to my sketch and notes: NGC 7635.

I've just barely seen it with my 10-inch from a very dark site, using an O-III filter. It's not what I would call an easy object by any stretch of the imagination.

The Bubble has both OIII and H-Beta emission, so it might be best seen in a narrow-band filter rather than an OIII line filter (although an OIII will also definitely help it). In the DGM Optics NPB at around 100x in my NexStar 9.25 inch SCT, the nebula is fairly easy to see, but I can only begin to hints of the arc-like portions which curve off of the oval central portion of the nebulosity. Most of the time, all you see is the brightest portion, a fuzzy lens-shaped patch (about 2' arc x 0.8' arc) around the 8th magnitude star SAO 20575. Under good conditions, the patch appears more pointed on its eastern end. This end just starts to curve southward and then abruptly fades away, which is usually the most of the "bubble" that I ever get to see. About 2' arc north of the brightest central patch is a fainter sort of "Y" shaped irregular patch. At lower powers, there is a larger very faint diffuse band of nebulosity (about 12' x 5' arc) running north-northwest to south-southeast that contains both the bubble segment and the "Y" shaped patch, but it takes outstanding conditions to see it. In the OIII, the nebula shows more contrast, but is fainter. Clear skies to you.
