Galaxy NGC253

Hi Guys,

Taken last night on my 10" LX200R at focal length 2000mm F8

20 x 5 minute autoguided exposures ISO400
Cooled canon 350D.
Sensor temp 2°c
Ambient 18°c
Humidity 70%
LPR filter used

Flats darks and bias frames applied in Imagesplus V2.8 finished in Photoshop CS2.

I have fixed up the reflection I had with the reducer but will never be able to get away with vignetting and field curveture at the edges, so you will see elongated stars all around the edges...no need to complain about that it's something I will have to live with or look at purchasing the lumicon OAG to replace my FR.

Pretty happy with the reults compared to last year.
