Behold! I ordered a radio knob at Conrads. It reduces the adjustment turns on my focusser 6 times. This way it is easy to fine focus on any object. It just costs me € 30,- instead of a "original" finefocusser of € 165,- :-)
Getting a step closer again!!! This week I bought a Baader UV/IR filter. This filter blocks infra-red and ultra-violet light. This light tends to blur the image. In the enclosed picture you can see the results. The sharpest image up to now! Although the seeing was poor! There is a slight colour abberation. I suspect that this is due to bad collimation. I try to fix that later on.
In this (over)exposed image you can see five of Saturn's moons. From left to right you can see Iapetus, Titan, Tethys, Dione and Rhea. The faintest moon on this picture is mag 10! I'm happy with the result.
After re-programming my webcam, i could use it to make RAW images. Altough they are in black and white, they are a lot sharper. All I need is a technique to proces the RGB greyscale images into a color image. But for the time being I very happy with the results up to now. If anyone has tips and / or tricks, please let me know.
Behold.... my finest result until now! It took me a while but i'm very pleased with this result. This photo is taken with a Philips Vesta webcam. I stacked 200 frames into this picture. The exposure time was 1/25 sec. per frame. To take a step further i will need a UV/IR filter. This will give a sharper image. So, another item on my next wish list...... ;-)
