[QUOTE="Paul Corfield, post: 1235778, member: 19132"] Right, here's my images using just prime focus. For the resolution score I went for 11 but looking at my printout the lines start to bleed together at around 11-12 so it's going to be hard to score any higher because of the limitations in the printing. On other parts of the chart where it only goes up to 10 I can see white very clearly between the lines so I'd say 11 is an honest score. Make and model of DSLR: [B]Canon 450D[/B] Make and model of scope: [B]Skywatcher Evostar Pro 80ED[/B] Type, make and model of camera adapter: [B]T-Ring with 2" scope adapter, both unbranded[/B] Length of spacer needed to reach focus: [B]85mm[/B] Focal length of complete setup in mm: [B]960mm after crop factor of 1.6[/B] Measured distance between target and telescope in meters: [B]6m 74cm[/B] Evaluated resolution number: [B]11[/B] Speed setting of camera: [B]1/1000 sec[/B] ISO: [B]400[/B] Original picture format (RAW, JPG) and resolution (mpx) [B]RAW 12.2 million pixels[/B] Date and time: [B]4th july 13:16[/B] Weather conditions (sun and wind): [B]Sunny, breezy but garden is sheltered.[/B] Other pertinent information: [/QUOTE]
