Went for a change of pace last night and broke out the 8" sct with ST7 to try to learn how to use the self-guide. After a few phone calls (thanks Dennis and Gerald) and a bit of hair pulling and cable swapping I managed to get it to work after a fashion. Time to try some imaging. M83. Nice and high, pretty clear night, just lums no colour, no drama no sweat.
Until the camera applied the autodarks.
Details: 3/5min shots at -15deg, autodark taken and applied using CCDSoft. Aligned, stacked and digital development in IP.
As you can see from the first animation, the NoDark has a bit of noise and the dark reduction has definitely removed the noise and smoothed the image, but what are the black chunks it's taken out? The dark bits are present in the same position in all the original FIT files. The Dark was taken at the same temperature as the lights.
The second animation is from the lower right corner so the difference can be seen more clearly.
