The scope is a Celestron Ultima 9.25 (probably 10 years or old...or more - http://www.rubiconbay.net/scope ). I was trying to decide between the TouCam and...
I tried to use a barlow (Celestron 2x Barlow Ultima SV Series) and have two questions - First off, the NexImage tube wouldn't fit into the barlow - anyone else...
The tube on the Neximage seems a bit large. It won't fit in my Televue 1.25 adapter that has the brass compression ring, but will fit into an older adapter...
I took the image of Saturn in the Photos section with the NexImage into an Ultima SV 2x barlow into a 1.25" visual back onto my C14. Everything fit fine. In...
A very nice image, Rob - well done. My NI was bought in December. Maybe my barlow is too narrow - dunno. I tried to fit it in again just now and there's no...
Thanks, that is by far the best image of Saturn I have taken. If the rest of your 1.25" eyepieces fit in your barlow, then I wouldn't think that your barlow is...
Just got off the phone with Celestron - the tech mentioned that the earlier models had an issue with the tube being a bit small with more play than they liked....
So my NexImage is an earlier model. That explains why mine has so much wobble in the single screw barlow tube (I would rather it be loose but usable). I am...
Is it necessary to use an IR filter with the Neximage when taking images of Jupiter or Saturn with a reflector? These fiters cost around 65 bucks and I'm just...
Wow - that's some fancy mathematics! Thanks - I can actually understand it. There was no dew involved (I went back to no barlow and focused just fine). The...
Since you can go more out of focus on either side, it doesn't sound as if you are out of range for focusing. It sounds more like there is something else...
Thanks for your thoughts - there is something I didn't try - and that was putting an eyepiece in place of the NI - so I don't know if it would focus in that...
Hi Pete, to answer your question: No, it is not necessary to use this filter for Jupiter or Saturn. For Mars it is, however, quite recommendable. There should...
I'd have to agree that the NexImage has a built-in IR blocker. In fact, unfortunately it's quite plainly bonded directly to the CCD's coverglass--- yes, I've...
Hello John, We are at least in agreement. I was allready starting to question myself on this. I will see if Celestron can tell me more about this issue. With...
Hi Cor, I hope you have better luck talking to Celestron than I usually do. I once even talked to a "tech rep" that didn't seem to know that their SCT...
Hi John, Ill try using my channel, NexImage and RegiStax are bundled .... ;) RegiStax V3 is hopefully a proper upgrade from V2. I will probably release a...
Hi All, already a while ago the question arose whether or not there was an IR filter included. At that time, around November 2004, I received confirmation from...
Just checked the old messages and located this: From: "Michael Swanson" <swanson.michael@u...> Date: Fri Oct 22, 2004 1:32 pm Subject: RE: [NexStarGPS] Re:...
One the Celestron web pages for the next image is one with reccommentded accesories. The quote below is from that page. "FILTERS Item #94125, UV/IR cutoff...

I've just uploaded two images to the files section in the file named "NexImage IR blocked CCD", comparing a stock TouCam 740K color CCD to that of the...
John, Thanks for the pictures. That reflective pink-magenta-ish reflection from the NexImage's CCD is THE telltale sign of the IR-cut filter. ccs_hello ... ...
just recieved my neximage. old laptop was not working, so i went and got a ibm thinkpad, running windows xp, 250 mb, 765 mhz. when instaling all is fine until...
Hi, I called Celestron about the unsigned driver, and was told by the Neximage tech to go ahead and install it anyway. He said windows XP acts that way with...
As mentioned earlier, it,s possible Celestron isn't aware that the chip is already blocked. I took a look at my unit, and the sensor array cover window does...
Now I think the real question is whether or not the IR-cut filter that came with the CCD is a good one. E.g., in Canon DSLR, people do extra work to remove...
