mega embarrassing mars and saturn images
i haven't processed any of the data i got on friday night because i was embarrased by the results. i used a bahtinov mask to focus on a star at f20 thinking that this would be good to focus with - how wrong i was. i went to mars first, and the image was dancing in the middle of frame and to be honest my eyes were telling me it was focussed but it somehow seemed very soft, but on the monitor i could see some dark bits. oh well on to saturn - it was like it was in a clear soup - wave upon wave of light warping and dancing the rings , but over all the image seemed soft. I really need to understand how you focus for these planets. i was using the new dbk21AU618 camera at f20 through the meade 14(f10 with 2x tview big barlow) on the titan mount . unguided the mount kept the blurry bit in the middle for over 1.5 hours while i was mucking about. I have posted some screensnaps to show those out there that this is the other end of the scale far from the Paul's and john's of the world getting fantastic crisp images of these planets.
anyway its only up from here
