There is some hope for Atik but Atik moves very slowly. So at least a year away. SX I have no hope. Even if SX starts using newer CMOS sensors will SLL get updated to use them? Right now it is not clear.

It would be nice to see other companies use IMX294. I only see ZWO using it at the moment.

 

Me too. Unfortunately other vendors are moving very slowly.

 

Interestingly, Altair has GPCAM3 385C, which is based on IMX385.

Perhaps Altair will come out with something based on IMX294.

If one wants to buy either an IMX294 or IMX385 camera. I wonder how IMX294 compares to IMX385.

 

I know IMX294 is a larger sensor than IMX385. IMX385 is a larger version of IMX224.

(Old thread)  Image sensor sizes

IMX385 is type-1/2" while IMX294 is type-4/3"

imx294 on Paper Evolutionary as a piece of Silicon.

Panasonic's use of it in GH5s is second.

First Use is < sorry Qhi(QHYCCD), I could not wait any longer>

Zwo ASI 294 Pro.

 

Sony imx294 BSI CMOS Micro 4/3.

a 35mm version of this slab of silicon promises >40 megapixels.

 

My first 2 images :

 
M51
 
M81 & M82
 
I know all the experts smirk,"amtuerish"...
 
 I am in Dense Populated skies.
 Have never had this ability with DSLR.
 I have never used a modern cooled camera
 of any kind.
 
 I have ZERO Technique.
 and, I have a big smile on my face...
 
 
P.S. - Click on the images to see the exposure data and other information.

Welcome to the EAA Universe...I have a Big Smile on my Face as your 1st results were far better than mine a few years ago...Back then, M82 looked like a featureless Cigar...Good Luck with your efforts as your results will get better and better with each use...Pat Utah  waytogo.gif

Nice images there. Just wondering what is causing that very large bright center spot in your M81/M82 image?

Two more possible design wins for the Sony IMX294 image sensor?

Thanks anyways but I received my answer via email and it is vignetting just in case anyone else was wondering what this is.

MallinCam came out with SkyRaider DS10c, which uses IMX294.

I think other companies will come out with IMX294 camera.

"other company will" is an incorrect claim or at best partially true. 

A follower should not say the other products already on the market as its followers.

 

For even later come to the market (by definition, such company has not produced the goods) will match the statement.

Not exactly sure what CSS_Hello meant, but the ZWO ASI294 is based on the same sensor, and has been out for a while.  

 

A couple of differences - the Mallincam has a much bigger buffer, 4 gig versus 256 MB

 

the ZWO is 10/14 bits, compared to the mallincam 8/12. 

 

The ZWO comes in a TEC cooled version, the Mallincam doesn't.  Mallincam claims CMOS cameras cannot (should not ?) be TEC cooled, for a variety of reasons.  I haven't heard that before.  The Mallincan has fan to enhace passive cooling

 

The ZWO has an on-board USB 2.0 hub, but no on-mount autoguider port.  The Mallincam has an on-mount auto guider port, but no USB hub.

 

I don't see any specs on read noise, dark current, etc on the Mallincam site that would allow a comparison of the two implementations.  I didn't hunt very hard, though.

 

As usual, the Mallincam is priced somewhat above the comparable ZWO canera ( ASI294, uncooled)

I kinda like the Mallincam's big buffer although it likely wouldn't benefit me.

 

I'm not sure there will be many who want to use that camera as a guider so I'm not sure a guider port makes more sense than does a USB hub.

 

Cooled CMOS cameras have been out for several years.  I'm not sure that delamination has been a problem as of yet (might be and I've just not heard of it?).

 

Does anyone know just how Mallincam arranges so that the sensors are "hand selected"?  I keep thinking it means someone reaches into a bin and their hand selects the closest sensor?  Maybe there is some special process they are using but I cannot think of what it would be.

 

I'm also not sure how "the software can eliminate all noises, hot pixels and warm pixels during live application or during imaging session."  There can and will be noise reduction, but I'm not sure how it could eliminate all noise.

 

Hopefully someone will do a comparison with an ASI294.  It would be awesome if the Mallincam camera were to prove actually superior because if they somehow got superior performance from a non-cooled camera we'd not have to supply power for the cooler.  I'm not holding my breath, but I'd like it if it works out that way.

IMO, Mallincam related/specific topic needs a separate thread, to avoid ruining this IMX294 sensor thread.

Cooling is worth it if available. The main question I’ve had for any of these implementations is if they support the native sensor binning mode, as shown on the data sheet. Does the Mallincam do that? I’ve heard that the ZWO does not.

For those SONY EXMOR CMOS image sensors, the on-"image sensor SoC" binning is just a software digital summing with precision truncated (very often significantly.)

I.e., no benefit at all, unless highest possible frame rate is needed.
