This is a sample of what can be seen with a modified Samsung SCC-A2333 or SCB-4000 security camera when placed into a telescope.
The camera modification: Removal of Factory IR filter, remote control added.
Telescope used for this example: Saxon 120mm f5 Refractor
Accessories: 0.6x Focal Reducer, Astronomiks 'L' IR/UV filter,
Mount: EQ6 (Atlas) with Skyscan GoTo
All video taken from extremely dark 6.6 mag skies at Victoria, Australia.
Nil Light Pollution.

These are some amazing pics! That's cool to stick the camera into the telescope. (or however it was done) This spring when Saturn was at it's closest, my neighbor got out his telescope and I got to see Saturn and it's rings. Kinda blurry, but you could see the ring. With his phone he somehow took a pic of it thru the tele. It was the first time I got to see the night sky thru a tele. It was amazing to see. They also had an app on their phone that showed what constellation you were looking at!
thank you Ken for the tips of the setting ,now just waiting to have a clear night to use it
I just ordered a scb-4000.... cant wait!
Excellent show, Ken ! Can't wait till your next show with the Peltier already fixed. : )
Keep UP ! Gabriel in RO
Wonderful, as real video of deep sky I had ever seen!
This is genius mate!! I finally got all of my spacers and adapters for the scb2000 to fit into my Hyperion eyepieces + celestron 8", going to give that crack when these clouds go away!! Beautiful video!

G'day.
The main noticable difference with the 4000 (SCC-A2333) is that it has the extremely sensitive Ex-View HAD chip and a few more settings than the 2000.
The finer detail is so much nicer.
I love seeing what that SENS-UP does at 6:40 Just freaking amazing!
Looks as if the 'stacking' is running so fast, it almost seems like you don't even need to turn on the tracking..
I find myself watching this over and over. And the music runs through my mind all the time. Looking forward to seeing and hearing more. Great Stuff!
These long exposure Astrovideo cameras use integration, which is similar to a stacking process. Each frame is 10 seconds long (or however long you set it) but the integration process allows you to see each stack of frames overlapping the previous stacked of frames making them appear as almost live, continuosly.
Super stuff, and WOW, with a 120 mm at that. What is the difference between the SCB2000 and 4000? I have the 2000, and broadcast myself frequently on NSN (AtTheEyepiece), so I'm curious if I would be gaining anything substantial by jumping up to the scb4000.
No Jr, no eyepiece used. Just a hollow nosepiece so the camera can be held in the focuser.
Very interesting and good quality comparing to other astro videos.......Could you please help me out and tell me how did you connect a remote control for accessing the OSD menu settings and what kind of remote control ?
It's very important not to touch the camera in these mods because slight movements can be shown....
Many Thanks..
Hi Nicholas. I made a tutorial on how to make a simple remote for the camera. It is here: www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/4117126/page/0/view/collapsed/sb/5/o/all/fpart/1#Post4407471
If you are testing in daylight you will have to reduce the exposure rate right down to 1/1000th of a second or even more.
If you are testing on the night sky it sounds like the brightness and contrast are way to high.
Download the program 'Gstar-Ex 4 Capture' found at myastroshop website on the Gstar-Ex colour camera page (download is at bottom of page)
and open it after your camera is connected and running.
Use the brightness/contrast settings for your camera.
It is the one I use.
Cheers
Ken
Great Work Ken.

excellent video
good show
great video as always i recently bought the revolution imager r2 and been looking at your videos , i see that on this particular video you only change the sens-up setting , is that basically the only setting you change when looking at DSO compair to planets thank you
- Thanks Tony, and yes, that is because the only usable setting in these Samsung cameras for DSO's is Sens-up. But in this model the Sens-up has two modes: 'Auto' & 'Fix'. The important thing with DSO's is to use 'Fix', otherwise the camera will keep self-adjusting and mainly over-exposing. There is no 'brightness' levels to change but AGC can be changed.
For Planetary on this camera, 'Sens-up' needs to be turned off and 'Shutter' is used.
Thank you so much for posting this video, This is exactly what I was looking for, do you have a video tutorial on how to mod this camera?
Sorry, but I gotta ask a dumb question. What are the lines thru some of the pics? Your pics are really beautiful. It's crazy to see those distant galaxies! I could see the Milky Way nearly every night when I was living in a pitch dark area on a lake.It was the first time that I had ever seen it! I was totally enjoying star gazing out there. And almost EVERY shower of stars it was overcast, or I forgot. Just my luck! Just thought I'd share that. I am so interested in the Universe! Thanx again!
Vegasjill21,
The trails (lines) you see across the screen are star trails as I move the Telescope from one object to the next.
I left them in the video to show that it is 'Live' video, not photos.
Hi Redwolf.
There have been many people testing all sorts of cameras for this purpose.
If you want to ask the people testing them, and find out what works, join the Astronomy Forum 'Cloudy Nights' .and go to the section called 'Video and Electronically Assisted Astronomy'. In there you can ask questions and discuss cameras with all of us doing this.
Cheers,
Ken
just checking but can the samsung scc-131BP or scc-131AP and the scc-B2305P work for astro imageing like you are doing in this video?
Hi ken just want to ask what capture card did you use to get the video onto your computer. Or video grabber as some call it. Thanks
I use an EasyCap Video Grabber ($19). I also bought the very expensive Mallincam one ($79) in the hope it would be even better but it was worse. It gives a whistling sound on the computer. Mallincam sent another one but it was the same and also had lower grade colour. They have never worked as good as the cheap ones for me.
BallaratDragon thank you ken. I do have an elgato hd but there’s a bit of lag say if I’m focusing I will see the result 5/10 seconds later. Drives me mad. Kool thank you 👍
Superb brother
Kenneth Cantu Hey thanks Kenn, thanks for watching : )
Cheers
Ken.
Can those video be saved in a PC and processed later on or is that only to be view at the moment?
Hi how did you connect it to the telescope? Whay is the adaptor style??
Kombinin, the camera is what is called a 'C' mount camera. It is named by the type of Lens attachment. You simply buy a 'C' mount telescope adaptor and put it on the camera instead of a lens, then insert it into the Focuser on a telescope. Here's an adaptor: agenaastro.com/blue-fireball-1-25-c-mount-video-camera-adapter.html
BallaratDragon thanks bro.
so to show this exposure you had video at 1 frame per 10 seconds?
@jambi99
That's great!
Make sure to watch my video on how to remove the Infrared Filter so it will work properly for Astronomy. The factory Infrared filter is too strong and cuts out way too much light. It needs to be removed.
To see my video in here search for 'Samsung SCC-A2333 Infrared filter Removal'.
Cheers
Ken
The camera attaches to the eyepiece?
Dear Ballaratdragon, I have just bought a SCC-B2333 from South Korea for this purpose.
In electronics I'am not very practical, I could better specify the changes to connect to the telescope/computer. I'm especially interested in the remote control of the device and connectors not BNC.
Thanks in advance for your cooperation.

Merry Christmas
Hello Gianni.
I am not sure of what you are asking.
The camera you have should work great even though it is only a 1/3" sensor.
I am not familiar with this model camera.
BallaratDragon
Hi BallaratDragon !
I'm sorry I was too brief, he he exceedingly. =:0) the correct model is Samsung SCC-B2313U. This camera has a RJ45 connector and the government through the RS485 port. It's equipped with a CCD SUPER HAD 1/3 " -
color sensitivity X256 0.0005 LUX,
B/W sensitivity X256 0.00005 LUX.
My question was just to understand:
1) as the swiped to the computer (with a normal BNC or RCA plug) ?
2) how you controlled the camera, if by chance you used a console type SHRS-2162, UDR 101/1616 (RECEIVER) or other mode ?
Thanks.
I know have a far better camera, the Mallincam Xtreme, so I hope to do another video soon.
@BallaratDragon I will! Thanks!
whats the song title ?
@jambi99
I can't remember the names of the three tunes I used, but they can be found on Danosongs which is a great website for Royalty Free music.
Sorry, but I'm sure it looks better when your viewing it live to you.
I don't get your meaning David. This IS live to you. Just a recording of it.
@eric99k
Hey, thanks Eric : )
I use Gstar-ex software to control the camera Brightness, Contrast, Saturation and Sharpness.
You can find the link to it in the Video Description above.
Uau !
