Thought I would start a new thread for this camera that NGCHunter mentioned in a post down below on an older thread on the SDC425.

Just got my SDC-435 today, will try to post some results to youtube under username "Astrobrick" this evening if it is clear out.

NGCHunter- did you get yours, any results?

that last one is central region of m37- on my screen you could pick up some subtle yellow and orange that didn't come across in the screen grab.

Looks like a decent camera. Thanks for sharing the images with us. With that said, unless we are talking about a particular target, like the M87 Jet thread, we like to have images posted in the Astro Video Image Gallery thread. Please feel free to keep posting more of your images.

They were very slow in getting mine shipped out the door so I'm still waiting on it to arrive. It's just as well though; I've got a ton of stuff on my plate for the next few days with regards to work. I'm excited to see your results though scout. It's given me something to look forward to once I survive my current problems. Thanks for posting the images!

couple questions please, where did you purchase the camera and did it come with all the wiring items in order to get the camera up and running, just one other thing, are you just experimenting with the settings or do you have a set of instructions written out. thanks, don

I purchased it from "123securityproducts" in NY they had it in stock a few days ago, you can also purchase from

Surveillance Systems Integration (ask for Kereise)
105 Vernon Street
Roseville, CA 95678
Ph: (800) 508-6981

They will be in stock starting Monday.

It does not come with the power supply- I got mine at radio shack for $9- it is the screw on terminal type 12v adapter.

You also need the BNC to RCA adapter (also at radio shack- $3) and a RCA video cable, and some way of watching or recording- I hook up to an USB-video capture device on my laptop, or if I am just viewing i use a 10" portable DVD player that has a video in connection cable for RCA.

You will also need either a c/cs video lens (the camera does come with the c to cs adapter ring) if you are going to shoot through a video lens for wide field or c-mount to 1.25" adapter for connecting to your telescope.

My settings for the images were:

Lens=manual
shutter=x512
AGC=off
D/N= Color
White balance= ATW, but I usually do the AWC-Set, probably why my colors are weird.

For focus and scope setup I have the camera set at:

Shutter = 1/60
AGC=low
Screen Brightness around 20

My viewing location is 50 feet from a streetlight and my garage internal light was on 25 feet away from my scope last night.

Hey scout,

Other than a longer integration time are there any other differences in the SDC 435 vs the SDC 425 I bought last year.?

BTW, I really like the SDC 425.

The SDC-435 uses a newer chipset, and slightly higher resolution (580TVL vs 600TVL for the 435) not a huge huge difference, but it was an overall sharper picture in the 435. I am not sure how, but the heat interference from the camera elecronics that I would get in the 425 is noticeably less in the 435.

I did notice that the 435 is more sensitive to how you step-up in integration, it will 'lock up' unless you take about half a second between steps when you increase the integration times and also lock up going from turning gain off/on , and you just have to cycle through going from off-low-high to off to get it to reset.

At this price, this has got to be one of the best deals out there to get your feet wet in Astro video.

I look forward to a longer session with this one soon when I have the scope setup better and can experiment with different focal ratio's etc.

That's fantastic news. I guess I got lucky picking the one that just sounded the best for the price. I'm really looking forward to getting mine in. I also ordered from 123securityproducts. Did you use express shipping or do they just not like me as much as they like you? lol

Scout72,

Few questions:
Do you know the name of the new chipset?
Have you looked at its IR-cut filter, is it removable or glued to the CCD glass?

Clear Skies!

ngc hunter: I did use the super express shipping- expensive but since it was coming from the east coast I didn't want to wait.

ccs_hello: the chipset is the Samsung proprietary processing chipset, W-DSP and NR chip version 4 which is the newest version from Samsung- the image sensor is 1/3" super HAD, but I haven't been able to find out which one.

Here is a UK magazine review of the camera (not from an Astro perspective though)

PS- unfortunately the IR filter is glued down and not removable. If they make this in a 745-SHC equivalent version with the mechanical IR filter and 1/2" chip and keep the price around $400 that would be sweet too.

Thanks for the report - sounds very interesting and keep them coming ;) Be searching UK suppliers for best deal :rainbow:
ps:shame about glued-on IR block filter - cam probably lost ~1/3rd of its 'speed' :bawling:

Hey Nytecam- while you are checking deals in the UK can you also see if you can find a price for a model called the SCC-A2333? I don't think this model is available in the states, and I am not sure how much it costs, but it is their newest model with 1/2" chip, mechanical IR filter and the specs give it a pretty remarkable lux rating of 0.0000006Lux in b/w mode with 512x integration.

Just an FYI for anyone following this thread- I have been trying to find out about pricing and availability of the SCC-A2333 model and also possibly "more better for astro" the scc-b2337 model which is a 1/3" chip model that does have mechanical IR filter and the newer generation DSP (but this one is A1 chip versus w5)

Just wanted to give a heads up in anyone is thinking about buying one of these.

Hey all. Am in then process of purchasing the orion 8in f4 on a cg5. Was hoping and praying to raise the funds for a mallincam sooner than later. I was doing this setup because it is the least expensive i have figured. Have not seen any of these cameras in real life, but am extremely interested now. How do they really perform...should i keep saving for the mc?

I like the idea of 0.0000006Lux ;) No luck with a UK Google search as yet for pricing :p Curiously on Sunday we has a pub lunch in nearby Chertsey and drove past Samsung UK HQ - must pop-in for a chat and see if they've any ultra-sensitive cams that need testing on my 12"SCT :lol:

Waggonner: Sorry I have not used a Mallincam proper so I don't have a reference point to help you with- I do know that with all of the money I have put into testing cheaper cameras I could have had a MC by now! I also don't have a big fast dob or hyperstar to do direct comparisons either! I do know that I have been able to see A LOT with these inexpensive cameras and I have been having fun with them, but i wouldn't jump on this thinking it is going to match some of the MC stuff you see people posting examples of.

Hey- try to grab one of the SDC-435's off the assembly line before they glue down the IR filter!

I have two Mintrons and a Mallincam VSS. One Mintron is a .001 Lux with Sense up to x64 the other is a .004 Lux, Sense up to x128.

I can see more through the Mintrons than I can see in an eyepiece but they are nowhere near as capable as the Mallincam VSS.

The Mallincam Jr. is quite a capable little performer, less than half the price of the big brothers.

Have you seen any of the Night Skies Network broadcasts?

Not possible. These are the result of a method of ordering pre-assembled IR-cut+AA filter+CCD all-on-one part directly from SONY.

Consider that H-alpha will not be so great. End of story.
$153 price tag is not bad.

Clear Skies!
