It has a c-mount thread, so you need to have a 1.25" barrel with a c-mount thread, and you should also get a focal reducer.

It is a standard c-mount thread- so you need a c-mount to 1.25" nosepiece that screws into the front of the camera that slides into the focuser. But it also depends on what telescope you are going to use and if you are going to use a focal reducer.

I hope to find out with another SamCam model I found and ordered- the scc-b2337. It does have the mechanical filter which is easy to remove, and it does have another version of the newer proprietary chipset- this one called the A1 as opposed to the SDC-435's W5- this is supposedly a step up. Other than that shares many of the same features as the 435.

one of the cool things about this model is the a1 chipset supports a coaxial hand controller- which, although it is more expensive than the camera itself looks like a nice accessory (scx-rd100)

Anyway- found the camera online for $123 and will post results (in the right place this time!) when I get it:

scc-2337 $123

Hi Scout,

Did you eventually get the SCC-B2337 and how well does it work?

I have sourced 2 models here in Australia, the SCC-B2337 ($380)
and the SCC-A2333 ($475)
According to the specs the SCC-A2333 is the better camera, so I am interested in why you say the SCC-B2337 is better for Astro than the SCC-A2333.

Hi Ken- no, I did not end up getting that camera- that seller was shady- I did get a credit though, so just a pain not a loss- but I did get the network/IP version of the same camera and I am very happy with it- that being said- i think I was comparing the b2337 to the sdc-435 when I said it was better- I do also have the A2333- and on paper the A2333 should be the best for astro use- (or the new SCB-4000) that being said, I really have not used mine much - but I did comment on it on the threads here recently- basically, for my light polluted skies I have not been able to use the camera to it's potential and I don't see a huge difference between sdc-435 images and A2333 when I have the best possible image from both on the same objects.

I saw your other thread stating you tried to order a sdc-435 and were told it is discontinued- I would check around a little for availabilty if you can - the camera has barely been around a year- the only reason I could think they would discontinue is if they have a new model to take the slot, or possibly because this camera is TOO good for the price and is hurting sales of the pricier models.

Thanks for the info Scout.

I would've thought that the SCC-A2333 would be the best of all their cameras as it is:

1/2" Sony Ex-View HAD IT CCD
0.000006 lux @ 512x color
0.0000006 lux @ 512x B/W

What about image size? One is 1/2" the other is 1/3" chip size. Does the chip size make any difference?

Thanks

Yes, it does actually.

The 1/2" gives a slightly wider FOV, and the larger pixels make it more sensitive.

Oh, and thanks to Chris for restoring my account back to being 'Dragon Man' again.

Anyone tried one on a 130mm f/5 Newt and have decent images?

Rick. See the latest posts here -
http://astrovideography.blog.com/
They are using a filter , but otherwise, I think those latest posts are not post-processed. They have removed the IR Filter in the camera how-ever, which is described in another thread in this forum:

After doing lots and lots of searching around Australia I finally found 1 company still selling the SDC-435.

They are asking $435 !!!!!!!!!!!!!!!!!!!!!!

Hmmmm . . . the ones on ebay for $129 are sounding even better

OK I think I'm sold on the SCC-A2333 but I cannot find a retailer. Has anybody found somebody willing to take money for them and if so what are they going for?

Thanks

Not available in the states- I got mine from ebay from Korea seller around $500 shipped- check with ebay sellers with good rating that are selling sdc-435 from Korea or Malaysia if you are still interested.

In retrospect, I probably should have ordered the PAL version for my uses since the full integration time would be 10.24 seconds vs 8.53 seconds (same thing for SDC-435)

That raises an interesting point. In many video imagers the PAL version has different (obviously) and often better specs. More scan lines, and longer integration times are two of the most beneficial. To take advantage of these benefits you have to be able to handle the different video output (different monitors, video capture devices). It has the potential to open up a real can of worms in terms of compatibility but if you know what your doing and tend to keep things simple you may reap some substantial benefits.

One of the other problem areas is power. Ideally you'd want to need only 12v DC but the PAL version of many commercial cameras also means onboard 220v AC power requirements.

It would be very interesting to put a PAL and NTSC based video imagers side by side to compare the images.

Very good points I should have mentioned- in fact it is going to take some tweaking to use the PAL version SDC435 I just ordered but I am pretty sure I can make it work with my capture device and laptop at least- it is 12v power I confirmed.

My thoughts exactly! Well, will see how long it takes to get here from Korea!

I have one the way as well, if not for using paypal I would have been a little leery of ordering something from Korea...

re: PAL 50Hz videocams used in NTSC-M 60Hz countries

A commonly seen problem is the AC beat 60-50Hz = 10Hz which shows up in the screen as a (slightly brighter) wide bar slowly scrolling (up or down). This is independent of if any device (including the TV/video monitor) is AC powered or not. If using AC power, the interference is even more severe. Without AC supply, it has something to do with the "grounding coupled signal". Very often the ground will influence/inject the 60Hz sine wave (if NTSC countries) into the signal path.

P.S. the ground is not 0 volt potential. It is also connected to the Neutral (the White-colored wire) in the house power panel as well as in all power distribution substations and power plants.

P.S., sometimes you can even hear the harmonics of 10Hz if the volume is not lowered.

P.S. the story is also true if using 60Hz videocams in 50Hz countries

Clear Skies!

Thanks Scout72,
I think I'm going to try to stay with the NTSC stuff. I am also over here in Afghanistan right now so I'll give a couple of local venders a try at getting it for me

Afghanistan is on the Pal system so you might not find any NTSC products over there
