Hello, I am relativley new to astrophotography , and I have a question. I'm using a n 8 inch Shmidt Cassegrain Celestron Telescope, with a 2x Barlow and a webcam. I tried removing the lens from the webcam exposing the chip, however it completly ruined the image, I would just get a big blur of light and shadow, so I put the lens back into the webcam, and butt the camrea up to the eyepiece with a special jig. I am using a Logitech C920 webcam. I notice people with webcams getting these pics of Jupiter and they are large images of jupiter , everytime I shoot video of jupiter to use with Registax , my image is so tiny ! I Was wondering if there is anything I can do to enlarge the image without distorting it to much . Thank yall
