wierd nebula near open cluster ngc3532

Hi
I imaged a strange nebula near NGC 3532 with the 10 inch after seeing it in a wider field 6 inch f3.6 image I took last week. This time no filters at all, as I wanted to get a full spectrum image, including infrared.
6x10 mins ISO 200, MPCC 10inch f5.6 newtonian Modded Hutech 350D with clear AR coated glass over the sensor so infrared is recorded also. quarter moon in the sky. Hand off axis guided
Full res. crop of the area plus a full frame view
Processed as usual in Iris and PS, resized in Paintshop pro
I dont know if the object has a name as its not on any of the charts I have.

At first I thought the yellowish white object is a galaxy, but it appears strongly in the UKST Ha survey plate so it appears to be a HA emitting nebula, but as its not red like the nebula nearby, who knows whats going on with it?
