That's very exciting, Sean.

What causes the jump in read noise at a gain of 120? It looks like you'd lose some of the benefit of the large well depth by having to run the camera at a high gain to reduce the read noise?

Hi,
Took my chances and ordered the ASI294MC Pro.
Like Colin, I'd like some pointers in dealing with the apparent read noise jump when the HCG Mode goes off below a gain of 120. Yes, will definitely want to use low gain for some targets.
No manual to be found.
Thanks.

Yes, 120 is the HCG ON point

Hello to all

This camera is really what I'm looking for.

What is the image format for RAW long poses ??

How to treat the matrix of Bayer 4x4 with software like Pixinsight ???

Best regards
Jacques

Received camera today, but unable to use the provided mini-CD for driver install. I need ASCOM and X2 driver for Windows, and X2 driver for Mac. Cannot find these on the ZWO web site. Please provide link.

Any manual yet?

Trying to figure out the best way to add an ir-cut or lp filter.
Will use T2 at the scope side, hoping to use the supplied M42-1.25” adapter for 1.25” filters just above the sensor glass - IF no vignetting.
Looks like some optics may have issues.
An T2 male adapter plate with clip holders for 31 or 36mm filters could be ideal.
Had hoped to avoid M48-filters, can't fit between OAG and camera.

Thanks.

ASI 294 seems very interesting to me.

Why so big dark current ? Dark current is about 10 times ASI070. How it will affect long exposures performance ?.

for example
ASI 294 PRO 0.025 e-/s x 600s = 15 ev
ASI 071 0.003 e-/s x 600s = 1.8 ev, less than readnoise

Not tested mine yet due to clouds, but I'm also curious about the higher dark current and how others (doing AP and not only EAA) have been dealing with it. (ok, a bit early after just recently hitting the market)

I bought the camera primarily for my C11HD w/Hyperstar (560mm f/2) to get better shots of comets and doing some NRTV/EAA, but hope I will be happy with the results at f/7 (the C11HD with reducer at 1960mm, and a refractor at 910mm) for some faint stuff.

That is, 600s exposures would be nice, but guess I have to go a lot lower.

it is the same as other ASI cameras
you don't need to bother the bayer because you cannot access it so close
they are output as one pixel instead of 4
