At 229X it appeared as an irregular elongated shape with no clearly defined outer edge. It was a smokey blue and reasonably bright even at this magnification. I judged the size to be about 50% greater than the apparent size of IC418 and brightness to be similar to IC418. Averted vision revealed slightly sharper edge detail. I could not see any central star.

Telescope Vixen NA140SS on TRex mount and LVW 13 & 3.5 eyepieces.
I have not yet had an opportunity to revist this one near M46.

That mag 14.3 central star looks a tough one Steve , maybe I'll try when it culminates, with a bigger SCT...than the 6 inch refractor .

Ive added some screenshots of where its located for others interested...and its distance from M46 for those without goto etc....about 2° 24'.33 ".

Skysafari plus is great for giving the distance between objects of interest.. and double star separations!....were getting spoilt now.
