Hi Brian - as I said at the start, I haven't noticed anything so far nor have I detected anything in the images from Sam and others using this camera with the rolling shutter.....

Torsten also noted no observable artefacts/effects from the rolling shutter in the "Ruby" cmos cam he tested recently...

My own thoughts are that it isn't nearly so relevant (ie, the "smearing" effect) with a single foreground image using high speed video - but that's a very lay appraisal..! :grin:

I hear also that the global shutter units might be much noisier...

On another note, I tested the colour unit for the first time today (very tentatively) and the 3-channel histogram displayed the channel sensitivities very much as you'd expect form the QE curve...

But Sam might have some more to say about the various sensors and why he settled on this one and the other I mentioned at the start of the thread Brian...

Hi Brain
From my test and experience. QE and the signal to noise ratio is the only thing should care about in astronomy.
Global shutter is good. but I don't want it if it has less sensetivity.

Contralulations!
its seems you made a big progress Darryl.
ASI120MM/MC has been used here for half year.
So actually lots of images taken by amaters here.
I will upload more.

Hi all! I maybe the first one to use 120MM take a astronomical photo. Here is a Saturn from 2012-07-06,Saturn at very low sky. And I only took RGB, not L channel.
Equipment is Skywatcher DOB10Goto+TV5X+ASI120MM.

Now it is a Jupiter in recent.
Equipment is Skywatcher DOB10Goto+TV5X+ASI120MM. ALL,include RGB filters and wheel. ALL make in China(BUT except TV5X, you can choice Meade 5X). So the total(not include myself and computer of caurse) of shoot this Jupiter only $1700. That is high recommend to beginners.

120MM support 1280X960@30fps, so I use it photo Moon too. Here is an example, Meade 3X instead TV5X.

It would be utterly remiss of me to not reply to your posts and all 3 amazing images ZZ - they are fantastic..! :waytogo: :waytogo: :waytogo:

And also I should say "wellcome to CN!" and I hope you will post here again in future.....I check out some of the AA forums in your part of the world occassionally and see some absolutely great planetary images: it's nice to see some being posted here..! :)

From my communications with Sam this last month I must presume you used SharpCap or something else for the Saturn at least, because afaik that was the only option untill very recently when Torsten started his work enabling FireCapture with the ZW Optical cameras....?

If that is the case then your achievements are even more outstanding - SharpCap isn't really "friendly" for mono cameras yet..! :waytogo: :shocked:

Guys hoe do you do such sharp image like this? I mean I can see details on Jupiter's moon and everything. It was taken with a 10" Dob. I have a 10" SCT so I should be able to take at least something close to this no?

Thank you,Kokatha. I have no idea about [SharpCap isn't really "friendly" ]...Since SharpCap work well. But maybe FireCapture will be a new world. I am quite excited.

Welcome ZuoZhao
FireCapture is more powerful than Sharpcap
it is the best capture software in the world
