  1. Starshoot Autoguider / PHD Guide / Celestron CG-5 Problem

    IS and craterlet It will work with a caveat. If your IS camera is B&W it is flawless. On my color cam it "works" fine. The file that it makes cannot be read by AVIstack or Registax. The reason for this is that it defaults to a bizarre codec that IS told me is proprietary. In fact, when pressed on the issue IS had me go into the file with a hex editor and change 2 spots in the header from BY8 to Y800. Here was their response. Thank you for your email. First of all, IC Capture.AS uses "Y800" as default video format and codec. The BY8 / YUY2 video format can only be set, if the codec has be set to "unspecified" in the AVI capture dialog window. The YUY2 videos can be read by "virtual dub" you can select in the "Video" menu at "compression" another codec, e.g. "uncompressed RGB". This may be can be read by your other programs. The files saved with "BY8" format can be edited using a Hexedito, e.g. "Hexwizard". In the AVI file are 2 locations with the string "BY8 ". They can be overwritten with "Y800". Then Registax can read these files. According to Stark labs, craterlet takes whatever the settings are for the camera. My first few pictures had this problem, and I took what the software gave me for those (I didn't reset any codecs). I cannot find a way to get Craterlet to change this. It also seems to me the By8 is pretty weak proprietary tech if one can convert to standard by changing a label. That is the only problem you might run into (and might not as they have made changes in the cameras over time). I will post some of the results with the chinese cameras once I get them up and running. John

    Chinese cameras I prefer Craterlet when it works. It recognizes many cameras. It is free and very simple to use. The first chinese camera came with adequate software to run it so I might try it. Registax 5 correctly loaded in the resulting AVI from its software and from Craterlet. AVIstack did not. It did load it, but said it only saw about 1/3 of the frames that Registax saw, or that Craterlet said it made. Not sure what that means at this point. John

    Well, on that theory I have already destroyed a Celestron NexImage. It was glued onto the chip really tightly. I got it off but scraped the chip pretty badly in the process. I was told by OptCorp that getting the chip off an IS could be easy. Some of theirs are glued on, some are not. You have to take the whole thing apart from the back and then reassemble it to find out. I don't mind losing a $50 gamble, but the $500 gamble I will pass on. I just bought 3 chinese webcam on ebay for $22 (total). One claims to be 20M, one 10M, one 8M. all have ir leds so should be able to see in the ir. The 10M has arrived, and gives good quality images at 1600x1200. The 30fps seems to work with my laptop, a Dell D610. However once I hooked it up through the docking station it slowed way down. I have no idea why. When I put my IR pass filter in front of it I got just blackness so its definition of night vision doesn't agree with mine. Still for $8, I may try to remove its filter. John

    Next one up doesn't have what I want The next one up has a built in IR filter. Orion says it can't be removed. One can take good pictures of the moon in daylight in the IR with an IR pass filter. I have a IS color camera, but made the mistake of buying one with the built in IR filter. Since I don't like to get up at 4 am, I can take pics of the waning moon at a more civilized hour if I have a camera that has no IR filter. Thus my interest in the autoguider which doesn't have one.

    Orion autoguider Thank you for the reply. I had hoped I could get double duty out of it. I still may get one for guiding, but would really like it to be a lunar imager too. Thanks, John

    Hi, I cannot answer your question, but if you have the Orion starshoot autoguider ($279) you could answer one for me. My understanding is that Orion software does not allow it to be used as an astrocamera for pictures. Looking at its specs it looks like it would take great lunar pictures. (B&W, 12??x 800?? 15 or 30 frames/sec and no IR filter (useful for daylight imaging with an IR pass filter). Anyway, I asked Orion to tell me if Craterlet (a free program from Stark labs for making AVIs) would recognize the camera. THey said the company will not allow 3rd party software on their computers. The question remains unanswered. I have been trying to find an owner of this camera to try this test, and would appreciate it if you could. It should only take 5 minutes. To do it: 1. Download Craterlet from stark labs and install it. http://www.stark-labs.com/ (under other software) 2. Install it; it easily uninstalls also when you are done; it is a small program 3. hook up the camera and wait for the usb "dah-dink" noise that says it found the driver. 4. Run craterlet. If it finds the driver it will come up and display what it is seeing through your camera. If you take off the dust cover you would get a blurry image with no lens. That is it. If it sees an image it will work. If it cannot find the driver it will not. 5. If it works, it gives you a nice lunar camera as an additional function. Before I pay for one of these cameras, I would sure like to know if Craterlet will recognize it. I am sorry I cannot answer your question, I would appreicate an answer to mine if possible. Thanks, John

    Registax I am familiar with it. I can certainly go that way. (Once I get some practice in...) John

    Contest question So does this have to be a still photo or could a video be submitted? I have tracking software so a 1 or two minute video should be theoretically possible. John
