Last year and this I've been checking out the faint but somewhat large reflection nebula IC1287 in Scutum. Its illuminating star is rather bright at ~5.5m, and the maximum dimension of the nebula in photos subtends some 3/4 deg.
A little over one degree to the east is a similar-brightness star which affords an excellent comparison. In my 11x50s I definitely see the haze of IC1287 (perhaps 15-20 arcminutes in diameter), whereas its 'companion' star looks distinctly haze-free.
Anyone else catch this one? I should have thought to report this earlier in the summer, as it's slipping lower in the SW nowadays.

Hi Glenn! I have logged this reflection nebula twice. Both were made with Vixen 20x100 binoculars. I glimpsed IC1287 in September 1999 from Sweden. The nebula was extremely faint and seemed to have a pinkish (?) hue. This was probably due to its low altitude.
Using the same binoculars from Namibia, IC1287 shone with a soft light around the 5.5mag double star Struve 2325.
The best way to convince real nebulosity is indeed comparing the double star's surroundings with the 5.1 mag star 0°.9 E.
