it was right away, but it was ~95 degrees outside. So who knows how it will look come a brisk winter night.

Also I need to try all the settings before I give judgement. But first observations seems to have serious noise issues.

If it was right away, the noise is probably not heat related so cooling would have no effect.

I took the picture with all the noise and used Neat Image to take most of the noise out and it looks a lot better.

What would it take to use this camera without the telescope?

A c-mount lens. What lens depends on what you want it for! If its just for testing, just get something between 10-20mm. You can get c-mount lenses cheap off ebay.

What if I wanted to set it up on top of the telescope but not inserted into the scope? What focal length would I need to see deep sky objects?

Hmmm that could get expensive. This lens is very wide but about the best I could find less than 100 bucks.

After that, it would be cheaper to just buy a small refractor telescope.

But with this lens at a max of 120mm of focal length, you could only view very large DSO's.

Jim,

Something in the same range as your primary scope (after the focal reducer is factored in). There's no magic here ... a 500mm lens is a 500mm lens regardless if it's purpose built lens or a telescope operating at prime focus. Think about the variety of DSOs though. At 800 to 1000mm (your C11 with an f3 to 3.7 focal reducer) even planetary nebulae are small ... but most of the brighter galaxies show up quite well, globulars are good fit but it can be difficult to frame big extended nebulae and some open clusters.

100-500mm is for large scale objects. These tend to be open clusters (Pleiades), those big extended objects (the Veil or the North America nebula) and the Andromeda galaxy. Down under 50mm and you're looking at really big stuff (the big Ha objects like Barnard's loop in Orion) or parts of constellations. When you are in the 20mm and under range you're looking at whole constellations.

Load up CCDcalc with the Mallincam specs and a bunch of representative lenses (you can work out the aperture of any lens by plugging in the f ratio and focal length). Then run through the sample object list (load up the additional catalog of reference images) to see what objects work and don't work at different focal lengths.

Anybody figure out a way to take the IR filter off besides using a cigarette lighter? Mine arrived yesterday but no one was here to sign for it so I will pick it up at the Post Office today.

I could not set mine to x1024. The largest number was x256. Also, I assume that motion detect should be "OFF". Has anyone figured out the white balance settings yet? You cannot use the Samsung 2000 settings since they don't go that high. It would really be nice if someone posted all of the suggested settings for everything.

I nominate Lee.

Can someone set up a paypal donation site so we can motivate him to get this done quickly?

:-) joking joking

Well James- I think you are one of three or four folks that have this camera currently so YOU may end up being the one to post the settings that are working for you.

You say you can only go to x256- is this in the Lens function? You have turned sense-up to off?

Motion Detection should be off.

It does not make any difference whether I have sense OFF, HIGH or LOW, I still cannot get any more than x256. Maybe they sent me the wrong camera! BTW, that IR filter they have on there is a real @$#% to get off. I also had to use a lighter.

Do you have the model number from the box just to confirm which camera they sent you? I thought that the entire camera line was either x512 or x1024...Just random thought- are you in the Lens setting for shutter speed? The only other setting that goes to x256 is the WDR setting?

I have to get some skies to test the camera first. We have had 100+ days for over a week. I have had about 30 min of total time under the sky with this thing.

Not sure about the x256 thing. I would check you got the right camera. If you pull the sticker off the DSP chip (the biggest one) it should say RJ-11.

I think they sent me the wrong camera. The model number that I ordered was LN-320-RJ11-673 which has the Sense Up to x1024. They sent me model #LN-320-RJ11-672. Its only one number off but it is not what was ordered. I just sent an e-mail to the shipper. And I had already taken the IR filter off.

OOPS on already removing the filter

I think the last 3 digits are for if its the PAL or NTSC version. In your case i think its the ntsc(673). I'm guessing...

It is NTSC/PAL- it refers to the chip- ICX672 or ICX 673

The shipper confirmed if i wanted NTSC or PAL after I placed the order-because the only one shown online is the 673- so if you ordered the 673 but said you wanted NTSC you are going to get the 672.

But this is moot- either of these is x1024 so James is either looking at the wrong setting or there is some other conflicting setting set wrong.

I can confirm a couple things after testing the camera tonight. I did some simple test, as the skies sucked. I just played with the camera in the dark. I found out that to reduce noise dramatically, Exposure set to HLI (start with HLI level 1), Sense up OFF, ACG any level (depending on what your viewing), lens set to electric and adjust exposure manually. Also set the 3d-dnr to max.

Try this as a good starting point. I'm now more excited about trying this out on the sky. Just remember, you have to exit and save after every change, else the camera will go back to old settings after a few min.

Lee

You da man- thanks sir- guess I have to actually go out and do some more testing now too...
