Image Issue Q&A / Re: QHY183C amp glow?
« Last post by QinXiaoXu on January 18, 2018, 07:43:28 pm »
It's difficult to run any tests at the moment because the weather is bad (no fully clear night since November) but we had a 2 hour window the other night that was partially clear. So I ran a quick test on M1. I calibrated with darks and bias but didn't have flats. The result isn't great and colours were biased toward green due to lack of flats and there was a lighter area top right that I can't explain and need to investigate (I removed it), but the glow wasn't apparent.

So the glow isn't a major problem.
Hi,
    Sorry,I can't tell from your picture that its lighter area at the top,could you please mark it out at picture?
Best Regards,

I have 163M + QHYCFW2-M-US combo. Could you please confirm that the new QHY183M will fit the same FW?

I now only use normal speed for everything. Should I switch to low speed?

QHYCCD Standard Software Q&A / QHY 174 & MaximDL 6.16
« Last post by rgsalinger on January 18, 2018, 01:40:17 pm »
I have the latest drivers installed on my computer and checked that I do using the driver checker. I have tried to use my QHY174 camera on two different computers and it doesn't behave properly. It connects. I can select it. I can select either capture or guide mode. I can vary the USB traffic, gain and offset. That all works. I take one exposure in either mode and it works. The second and all subsequent exposures return in 1/2 of the correct time or even less. I have varied everything I can think of - cables, hubs, usb traffic and it's still the same deal. I set the exposure to (say) 5 seconds and the first exposure is OK. The next exposure comes back in 2 or 3 seconds instead. If I then set the exposure to 2 seconds, the first exposure comes back fine. Subsequent exposures come back in half that time. Any time that I go into the driver GUI the system seems to reset itself and the next exposure is the correct length. After that initial exposure all of the following exposures are too short. It works in the SKYX using the X2 plugin but NOT using the ASCOM driver. It works perfectly using the ASCOM driver in PHD 2.6. Hoping you can give me a fix for this. I see exactly the same behavior with my old QHY5-IIL mono guide camera using the same driver but selecting it rather than the 174.

New Camera Information / Re: Any plans for Sony IMX 327 integration ?
« Last post by xs_man on January 18, 2018, 11:49:55 am »
Thanks Qiu !

From my point of view it has a great potential (I hope !) but it's important
to evaluate it.

It's not the quickest sensor for bright planets imaging and it's low saturation
signal value make it not suitable for long exposure use. The most important
for me is to know if it's (or not) a great sensor for planets like Uranus,
Neptune (and Saturn) and more important a great sensor for DSO short
exposures use ??

Other important question : Do Sony plan a monochrome version ? This sensor is
presented as the IMX 290 successor !?

New Camera Information / COLDMOS cameras - binning and bit depth
« Last post by jaimea on January 18, 2018, 05:13:15 am »
Hello,

I just wonder how the binning in these cameras is internally done. If one camera has a 12 bit ADC, but then is operated in bin 2x2, is the output effectively 14 bit...? That is, the binning is performed after the ADC?

Thanks,

jaime

Astronomy equipment Discussion board / Re: Polemaster App on Google Play store
« Last post by Fulhair on January 18, 2018, 05:04:11 am »
Hello,

      Yes we just released a beta test version. So the Google Play Store should be beta version and the list price is USD18.00 for final price. Due to some mistake the beta version is marked as the price and we are changing it to a free version. Please wait for a moment to refresh it.

       The beta test version is just for testing propose. And welcome the feedback. In this version it currently only for north sky. And also it has some limitation.   

        Normally you do not need the powered hub. Just a normal cellphone hub is ok. directly cable is also ok.

Best regards,
Qiu Hongyun

Great news,
Will mean I don't need to drag my laptop out into the field all the time I set up my mount.
I would love to do beta testing on it but I'm located in the southern hemisphere so can only do some initial testing and not the full alignment.
Will have to see what cable options are possible for connecting my phone/table from a micro usb to the usb A or mini port on the polemaster.
Cheers
Andrew
