Test image around NGC 3263

THIS IS ONLY A TEST IMAGE of the the field I'm using for the commissioning process. NGC 3263 is 6.2 x 1.4 arcmins in size.

During this 40 minute exposure (comprising 8 x 5 minute subs) I discovered I have a guiding problem by virtue of the fact that the payload on the Paramount ME is now larger than before (45kg or nearly 100lb). I believe the spring plunger adjustment on the RA and DEC axes needs tensioning. I also probably need to reduce the acceleration of the mount. The stars in this image are actually elongated towards the bottom of the frame. Collimation is also not as good as it can be.

FOV is 38 x 25 arc minutes @ 0.59 arcsec/pixel imaged between 31 and 41 degrees altitude with average seeing. Some cropping to eliminate stacking artifacts. Processing was minimal with stretching and some noise reduction only. No deconvolution was done. It's looking promising for sure!!
