Hi all,
Here's my latest pic, NGC3293, a favourite star cluster in the constellation of Carina.
The image is a 60-minute (15x4min) autoguided exposure @ ISO-200.
I am quite happy that this image not only showed blue nebulousity around the cluster but a close inspection shows that the blue nebula has distinct variations in brightness.
There's a higher resolution image here
