It took me a few months to figure out what the problem was. It was a focal length issue and the webcam image sensor was not able to reach the focal point of my Zhumell 10 inch. I took out the image sensor from the webcam and placed it half way into the eyepiece hole. Luckily, the hole was big enough to accommodate the image circuitry. I taped this arrangement inside the eyepiece to avoid any disturbances. With little adjustments to the eyepiece focusing...BAM! I had the image of the moon.
So for guys who are trying to take a picture of the moon with a webcam and you see that your image is blurry no matter what you do.. You know it’s a focal length issue. Just try to do what I did above and you should be able to get a view. I used wxAstrocapture to record an AVI file and then used Registax 6 to process the image. I know that there are tons of images of the moon out there... but for me this image will always be special.
My first astro image! A processed file. |
