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 :confused:

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.

So I am a little confused. Does this mean it is limited to X16 for exposure? Also what does X16 translate to in number of seconds?

No- it just means you don't have manual control of the exposure. It does have the ability to go to 1024x (1/50th or 1/60th secondframes =PAL or NTSC) = 20.4 seconds for PAL- but you can't set it there and keep it there- but what we haven't tested yet is if we set brightness all the way up and target something like a dim galaxy or neb for example and see if the camera will "figure it out" and keep trying to expose for that.

I do know of some folks that use the sdc-435 this way in auto mode and it actually works pretty well so I am still hopeful for what this cam can do out of the box.

Anyway- for Hemmi- my guesses on settings if it helps:

Exposure to "Normal"

Then Sens-up = x1024 (this is only telling the camera it CAN go to x1024 if it needs to but doesn't force it)

In Exposure menu set brightness setting all the way up telling the camera to overexpose as much as possible.

There is also a Lens setting - which again does not have a "manual" option- I believe the correct setting is DC IRVs then speed= 1/50th- but this is a guess since it does not have a "manual" setting here- the other option is ELECTR for lens which I believe means that the camera tries to adjust brightness electronically - an area for testing.

I would probably start with AGC to middle for starters and Gamma (in Enhance menu) to 0.45

I took mine apart and removed the it filter. What a pita...it was glued on...a little heat and it popped right off. Going to test it tonight!

Cigarette lighter - yikes! From my quick inspection it looked like the filter was in a sliding mechanism- usually you can just wedge something in after it opens and this will keep it open- but will report back after I actually verify-

Nope its not mechanical. Just looks like it!..I was in a super hurry...on the road now to SC and darker skies! Tested the camera afterwards and all is well. I would do NSN but my netbook flash crashes with NSN...But I will get some pics up tonight.

Oh boy- well I am sure Hemmi will figure this out but THIS DOES HAVE manual shutter, was working with this cam a little more this afternoon and figured it out...if you turn Sense-Up off in the sense -up function then the Lens function gets the sense-up speeds and they ARE MANUAL! WOOHOO- well- will still have to see :foreheadslap: how it performs at 20 seconds...getting dark soon.

Well this thing is super sensitive...But Noise seems to be an issue at the moment..But it is 85 degrees right now...Here is a pic to chew on!

A lot of quirky things about this camera, but with some tweaking and good skies it may have potential. Seems to pull in a ton more light than the sdc-435 at the same exposure. However noise seems to be worse. With some tweaking I think it will do ok...still yet to try with lowering the gain..that may help with noise. Also better skies will give a better indication.

Well done Hemmi for 1st DSO pics - looks very promising and manual shutter afterall say Scout :jump:

Did a quick test of your [boosted] M20 against Megastar and its down to mag 12.6 and pretty clean from hot pixels - M21 OC top left :rainbow:
