Neximage Jupiter 3rd time out

Hi Everyone:
Here is picture of Jupiter taken on November 11th with my celestron neximage and my celestron cpc. This was my 3rd night out using this camera. I am happy with it. I bought the neximage used for $45. This was taken using a 2x barlow and stacking about 600 pictures. I had a frame rate of 10 per second, with no gamma, gain and saturation set so that Jupiter appeared just a little darker than normal through an eyepiece(a little less than halfway). Seeing was average.
My question is does a UV/IR filter help?

Any other suggestions/feedback welcomed. I plan on pushing this camera to the limit! Who says astrophotography has to be expensive.
Thanks for the feedback.
Jay

I use a Neximage and have had some good results with it. A UV/IR filter does help some but the key to getting good images with the Neximage is to convert it to RAW mode. Celestron has instructions on how to do it.

The NexImage already has a IR-blocking filter bonded directly onto the CCD coverglass. If it didn't, you wouldn't be able to get good color balance of daytime scene with it.

One reason that the early Philips ToUcam models were so popular was that the IR-blocker was part of the lens assembly, which was removed to mount the 1.25" adapter. So one could use a screw-in IR/UV blocker in the adapter for good color balance, or remove it and use an IR-pass filter for near-IR imaging. You can't do that with a NexImage because it's CCD is permanently IR-blocked.

A few years ago I did some testing of the NexImage built-in filter, and it blocks IR as well as either an Astronomik IR blocking filter or the Baader IR/UV blocker (also sold rebadged as the optional Celestron filter). I did not have a good way to check on the UV end, but it did indeed have noticeable UV blocking too.

The only reason to use a screw-in IR-blocking filter on a NexImage is to protect the CCD from dust.
