I'm trying to get a photo of Jupiter and Saturn with my Nikon D3000 DSLR but I can't get anything clear. I attached the kind of photos I'm getting with my camera. They end up being too bright and no distinguishable features show up. Is it even possible for my Nikon to get photos of planetary objects like Saturn and Jupiter?
Jupiter with two of its moons, Ganymede and Callisto, imaged with a Skyris 618C CCD through a 8" SCT at f33.
I am thinking of re-starting mirror grinding at home. I used to grind by hand and in this method, when we use the 1/3rd off-centre strokes for hogging out the sagitta, the upper glass becomes concave and would be polished into a mirror.
However, this time I'd like to build a Mirror-O-Matic or something similar and do not understand that if the tool is on top, how will the bottom glass become concave?
Or am I mistaken?

An image of Jupiter with a transit of Io, showing the moon and its shadow, plus another moon (Callisto). This was the best of a number of images. I used shorter runs of 3000 images while contending with thin moving cloud, then 5000 when the cloud moved away. But the seeing seemed to deteriorate, so this is the best image. I left the gear out in hopes of imaging Mars later but by 3am on the 18th, the sky had totally clouded over.
Equipment: CPC800, ASI224MC, ADC, processed in Registax6. Best 20% of 3000 frames.
The "Wavelet" section of Registax has six sliders. I have been in the habit of using just the top one, but adding some action with the second one definitely improved last night's set of images.
