filters????

hello all,
could you folks try to explain the differences between the baader ir filters.(ir block, hi-pass, contrast booster, ect). i am confused. i am using an unmodified phillips 900 webcam for planetary imaging and would like to get more contrast/detail. which direction should i be going towards? here is an example of what i am getting now. would a filter of some description help?

image was a stack of about 30 frames taken through a 10" dob. collimation was real close and i feel focus was pretty good. any help???

Hi Huck

How high will Jupiter get for you this year? Surely it doesn't get much out of the muck.

Your main problem is going to be the altitude and seeing. No filters are really going to help you with the ToUcam.

A monochrome camera will help a bit, and an IR pass filter might help with the low altitude and seeing. But really you're gonna have to wait a few years until it gets higher from your location.

Huck, a visual bandpass filter might help - the rgb filters built into the ToUCam are not very precise and a lot of IR/UV can get into the camera and cause some blurring of the image. A visual bandpass filter will block anything outside the visible range, could be quite helpful.

cheers, Bird
