Imaging Challenge- Abell 23

I like a challenge so have been trying to image some of the Abell PNs. This one is Abell 23. It is conveniently located high in the west in the evening. Other info is:

Name: PK249- 5.1
Type of object: Planetary nebula
Magnitude: 13.1
Size: 54.0"

Right ascension: 7h 43m 35s
Declination: -34° 46' 36"
Constellation: Puppis

My picture is taken with my Genesis CCD at aprox -25 C. Exposures were a mix of 5 and 10 min exposures on 2 separate nights. Total exposure of 1 1/2 hours with no filter. Darks, flats etc as usual. Field size is 14 x 9 arcmins through my VC200L
Still pretty dim but visible. Maybe someone else would like the challenge?
