I have been unable to get a clear answer on whether a IR/UV filter is helpful in imaging the planets. Celestron website seems to imply a filter is required....

The neximage has an IR filter integrated, I'm not sure if the camera is sensitive to UV light. If you make the light reflect in a certain way you will see the...

Hi, I agree that a 2X Barlow is probaly close to the limit. Like you, I use the Neximage on a CPC 800. And a 2X Barlow is the maximum I have used for Saturn....
