From this baseline, there are multiple directions to branch into. Some will say the ROI (return of investment) will not be that great any more . Of course everyone is entitled to have his/her own opinions on those factors.

I couldn't agree more... a balanced approach ends up with a better overall result. Balancing scope to mount to camera.

I spent a year trying to figure that one out.

One of the things that would make a great sticky for those just trying to dive in, would be a low, medium,high (price) "standard" for hardware for real time imaging.

maybe something like a ioptron refractor/samsung... a C8 or LT6 with a DSI III (or something like it) and a bigger meade/celestron with a mallen..

just thinking a few cookie cutter "it's all been figured out before" options might help folks.

SDC-435/SCB-2000:
Pixel Size
NTSC 6.35um * 7.4um
PAL 6.5um * 6.25um

Lntech Cam:
NTSC 5um * 7.4um
PAL 5um * 6.25um

Sony measured sensivity @f5.6 (standard sensitivity test)

Sdc-435/SCB2000 Superhad II:
NTSC 2250mv
PAL 2250mv

Lntech Cam Exview II:
NTSC 2450mv
PAL 2400mv

The sensitivity charts are interesting too for the 960h exview chip- more red sensitivity.

Be advised- this camera may not have full manual shutter/sens-up- won't be able to confirm until I test the camera in person-

I did get a response back form the seller with more details on the DSP menus - but have not gotten confirmation that it is mechanical/sliding filter- but from the menu information I have seen I am not sure that this camera has full manual shutter control.

Yep- true ICR- so should be mechanical IR filter which is good news:

I noticed the Menu usage page also states a max of x256 on exposure menu. So who knows whats really there. Did you ever find out what DSP this thing uses?

I did ask that question about the x256 in the example - guy said that was only because it is a generic manual sheet from an earliuer version of the camera- he said it absolutely does sens-up x1024

No answer on the dsp

Brian,

Thanks for helping me identify one mistake I made:

Std reso (480H) pixel width is 9.8um, high-reso (720H) is 6.35, and super-high (960H) is 5um. So area-wise it's supposed to be 1 : 3/4 : 1/2. But the actual value on
high-reso vs. super-high is just 27% more.

Regarding that sensor output avg voltage level, indeed SONY datasheet calls it "Sensitivity". But that is far from the good definition of "sensitivity". As I had stated in my earlier post I don't want to touch the (loaded) word sensitivity . There is a long story...

Clear Skies!

Re: loaded words- yes I hear you loud and clear!

Okay- Think I found out what DSP is here- it is RJ Electronics of Korea- version R8 or Rj9 - new one on me.

And lookie here- looks like it is programmable with an extension board via USB and has the instructions for changing the timing....hmmmmmm

very interesting. I hope it will do manual shutter up to x1024

Well sorry guys- no full manual/ fixed sens-up. Got my camera in the mail today- express shipped. Will do some night testing to see what it can do in auto mode. Will also shoot off a message to RJ about the DSP to see if there is any way to approximate manual settings.

That's a shame - hope a fix is possible

Well that's a bummer. Look forward to seeing what you can get out of it regardless.

I got my camera also, I have yet to test it. Will try tonight if I get a chance.

Brian, any update on your testing?

Actually I just haven't been able to test- I just moved last week and still getting set up at the new place (but it is slightly darker skies at the new place- yipee)

Hopefully this weekend but at this rate Hemmi will probably beat me to first light with this camera.
