Here is my last image of mars. The image size is 640x480. I used a Meade 10" LX200 f10, 5x Powermate. The distance from the top of the Powermate to surface of the CCD is 20mm which gives a multiplying factor of 5.5x (see table from prevoius Posts). There for the effective focal length is 13750mm. Divide this by 50 and we end up with a magnification of 275x. In terms of image scale we end up with about 0.11 arcsec per pixel. Mars diameter in this image is 17.65 arcsec.

P.S. the wife got the nappy job.
