NGC 2899, the flying jaw nebula.
This was my test target for 300 sec exposures last night, before the moon rose. The first image is cropped from the wider field version (which has not been cropped at all) and gives a indication of its size within my FOV.
I'm happy enough with the results for this, especially since it seems I can get useful images out of ISO 800 + 300 sec from the backyard.
