Ok just for the sake of the board (And my used camera pile), I ordered a cheap SDI HD Cam from Securitycamera2000. To save cash I got a board cam with no case. I figured this way, If it is useless I save money. If it works out good, I can just CNC a case for it on my CNC router. I also picked up a cheap SDI to HDMI convertor so I could hook it to a TV or projector. I will be able to capture images only in standard resolution ATM, because I am not waisting cash on a HDMI grabber just yet. But I can take HD pictures of the screen so everyone can get an idea of the image quality. This cam has composite also, so I can broadcast with it also (In 640x480 of course). The HD is only for my personal viewing pleasure This will only be used for planetary. I bought all this in the US, so should have it fairly quickly. Will report back when I get it.

Great news man i look forward to seeing the results!
Couple of daft questions for you. 1: Don't you have the MCV-1-E HD (latest mallincam grabber) and woundnt that capture HD? 2: Why cant HD be broadcast in NSN? It has the resolutions HDTV, HDCAM and FullHD so what am i missing there?

Chris, Good questions, I will do my best to answer. 1. Yes I could use the MVC-1-E, but I would need a few conversions. I could get a SDI to component convertor (If I could find one for less than 200 dollars). Also I could go from sdi to hdmi to component. Once I see if the camera works ok, then I will come up with the cheapest method of getting it to the PC. Obviously the best method is SDI to USB3 (Very expensive). 2. NSN now apparently does support HD video all the way up to 1080p. So this remains to be seen how well that works. This must be fairly new offering by NSN. Never seen those resolutions available before. So in short, you missed nothing I was mistaken Regards, Hemmi

Ooh great news Hemmi! I look forward to the results. If this works well we are going to have to figure out a way to broadcast in HD. I've been looking recently at various HD SDI cameras, but my head is now about to explode with info overload. I've gone from HD, to 3D to 4K, the Red One etc. etc... Must get an extra lottery ticket this week!

Also we dont require a fast FPS for NSN. A low FPS 720p video stream should be only 1mb/s or so. Flash uses high compression. The real question is how often flash crashes trying to encode HD video..LOL Hemmi

I got my hd-sdi camera. I played with the OSD controls and it looks like I have full control over exposure settings, brightness, acg, color, day/night, sens-up, etc. So this may work fine. I just need to find time to get the scope out. The cheap fleabay sdi to hdmi works great as far as I can tell. Playing with a standard CCTV lens the image was very nice. Calling for cloudy skies all weekend so it will be some time before I can test out this camera on the scope.

Great news Lee, very much looking forward to seeing how this one goes but sounds good so far.

ok it was hazy but jupiter shown through, so i tried out the hd-sdi cam. Im sure on a clear night this would be much better, but it seemed to work just fine. Detail was lacking, but I blame a lot of it on the high hazy clouds. The good news is I was able to control the setting just fine. Here is a snap from my phone of the monitor

live view was much better than the picture shows, but still not great. On a clear night I would expect the image to much better.

Here is a snap from my phone of the monitor Interesting Lee, what telescope was you using? When the weather clears it would be great to see a side by side with a normal cam under the same conditions. It would also be good to see how it looks on NSN. I normally always take a picture of the monitor but for some reason Jupiter never shows well. I normally get a frame grab with this target or take a snap in Miloslick as it's hard to demonstrate what you see yourself live.
That said however, I think the best test for HD will be the Moon when it's back. Thanks for posting and looking forward to the next instalment!

To be honest Karl it looked exactly like what I would expect from any other cam given the same conditions. The scope is my 10" Dob with a 3x barlow. I too bought this cam for the moon, hoping it will shine there. I think it will. I think with better conditions Jupiter would look much better. The phone camera made it look brighter and duller than it was on the screen. I want to see what a HD stack of jupiter will look like. Now that I know it at least works, I will get a grabber so I can broadcast and stack. Conditions blur jupiter the camera cant overcome that. Hemmi

Got the HD grabber today, good news is records fantastic video, bad news is its not compatible with NSN. I can use webcammax to broadcast the HD grabber window, but it is limited to 640x480.
