Here are some Jupiter pics I took with my celestron c11 edge HD,DMK 21 camera and rgb filters.I took these just before dawn so there were no stars to use as focus so I used one of the Jupiter moons.I dont know if the blur to the images is from poor focus or collimation.Any tips to improve the images?

Just need the focus sharpened. Best way to check the collimation is do a star test.

Agreed! Very nice images esp the 1st one. Focus is perhaps a touch off but the DMK has done a very nice job.
Well done and very nice!

Thanks guys-I appreciate all the comments,
I guess I will have to get up even earlier and focus on a star and then slew to Jupiter. I just bought some Bobs Knobs to help me collimate because it is really hard to adjust the factory screws in the dark.
When you are collimating is it important to make sure that all of the three screws are tight? I have noticed that I collimate on a star near the zenith and when I slew the scope the collimation sometimes changes.When I then check the screws sometimes one of the screws is very loose so maybe the secondary is moving?
I love the DMK camera.Apparently they have just released a much more sensitive version that has the same ccd as the flea3.Cant wait to see some images from that.
I am using registax6 for processing and I find that in wavelets when I increase the wavelets I have to increase the noise reduction to smooth the image and that makes them a little fuzzy too.I guess I need better seeing so I dont need so much processing!
