I use these cameras for FPV. They are very unique cameras, that are different than anything else out there. Each pixel acts as a separate camera, by controlling exposure etc. You can point these cameras directly at the sun and you can still see the background around the sun. It does this by automatically adjusting the exposure of each individual pixel. These cameras are also very sensitive and contain sensup function. These may work fantastic for bright objects such as the moon by dimming the bright areas and bringing out detail in the dim areas. I also would like to see how it handles something like M42 with the bright core. Also, will this work for jupiter and still get the moons? The dynamic range for these cameras is off the chart. The noise level of these cameras remains to be seen, so they may or may not be suitable for deep sky. The good news is I have one of these cameras, and I plan to run some test. My camera is a very small 690tv line ultra wide camera. My camera sensitivity is not stated with sensup, but there are some out there with impressive ratings. Here is my camera, the page gives a good description of the technology. www.securitycamera2000.com/products/690TVL-Ultra-WDR-Pixim-SEAWOLF-HD-CCTV-Mini-Camera-2.8mm-Lens-OSD.htmlAnd here is a box cam version with impressive specs - www.amazon.com/Vitek-CCTV-VTC-C770WS-Seawolf-Powered/dp/B005UPUHSU/ref=sr_1_1?ie=UTF8&qid=1391696908&sr=8-1&keywords=Vitek+CCTV+VTC-C770WSI plan to test this on the moon once I get the 1.25" adapter I ordered. Time will tell if this is camera has any use. I will let you all know. Here is a FPV video I made a few years ago with this camera, notice how the bright sky does not wash out the ground (not at my bad flying LOL) Hemmi

The PD1 camera states on its site that it uses a Sony super HAD 2. I'm interested if anybody has used the Pixim Seawolf sensor. But that link from newegg looks like a good price for this sensor and with x1024

My main interest in this sensor is for planetary imaging. The moon being my primary reason. When veiwing the moon we constantly have to fiddle with the controls to dim brighter regions or brighten dimmer regions. I want a cam that really capable of displaying the dynamic range of the moon properly. The Pixim has the greatest dynamic range of any camera I have ever seen.
But if it works good on some DSO's also that's a big PLUS. These cameras are more expensive then their sony counterparts, and only recently have they came out with versions with DSS. I have not found one reference on the web to anyone trying this sensor for astro video yet.

Also I have a graveyard of crashed planes, helicopters, and drones. Think astronomy is expensive, its cheaper than crashing a $1000 dollar plane LOL

Looking back it looks like ive seen it was double the price of the super had cam but thought it was the same thing If its a far superior sensor and it has x1024 $200 is pretty good.

Ok I got a wild hair and decided to recase my Pixim camera. I took an old ln300 case and shortened it by 2 1/2 inches. Rewired the rear control panel to work with the pixim sensor board. Now the ln300 OSD controls work on the pixim seawolf, and the BNC and power connections all work also. Now I can use a standard c-mount to 1.25 adapter will work. Now I can test the proof of concept, however my model only does x64 sens. But, I can test it on the moon which was my original purpose anyway. If this shows promise, then I can spend a bit more on one of the more feature rich pixim cameras. From the picture you can see the sensor strongly resembles a cmos. Here is the re-bodied Pixim:

Nice work man!! You don't hang about lol
How does the focus thing work? Does it actually move the sensor or something?

The farther to the right the blue bar goes, the sharper the image. Its similar to the focus assist used in some imaging software. And no I don't just sit around once I get a wield idea. I just go for it. LOL

Looking good Hemmi! Hope you get good results. Thats also good to know the two boards are compatible.

Cutting traces and soldering jumpers. LOL I reality I bypassed all the circuitry and just used the buttons, power connector, and BCN. It was a pretty ugly hack, but worked like a charm.

. . . . and the official report is . . . .
Well, did it work Lee? Did you try it on the moon?

Weather calling for partly cloudy skies, so may get a chance to try it tonight

Good stuff Lee. I had to pack it in tonight about 2 hours after I started. Got clouded out.

Ok I guess partly cloudy does not mean the same thing to the weatherman then it means to me. Anyway I snapped a few moon shots with the Pixim sensor. This was not a great test as it was not even dark, and the mount not aligned. Also it was hard to judge focus due to the clouds. Anyway here is what I have so far. Camera seemed to handle the changing brightness and contrast well. I never even had a chance to adjust any settings (camera or computer). This is as raw as it gets. Capture card was doing something funny at the bottom of the screen.
