Jupiter with C8

Finally the Celestron C8 is restored. Last night I had to make some test images To see if the telescope was reassemble in a correct way. This image was taken with a Philips SPC900 webcam. 900 frames where stacked in Registax. The C8 was placed on an EQ6 Syntrek mount. At the left hand side of the image is Io visible.

The effect of a Ha filter

This weekend the new Ha-filter arrieved. This 12nm EOS clip-inn filter had to be put up for the test. The week before I allready had the chance to image NGC281; The Pacman nebula. So I added 12 frames of Ha (360 seconds at ISO1600). After scouting the internet on Ha processing I came up with this result. Left without Ha signal; right with Ha signal.
