Hello,

one of my "colored moon" have the AAPOD2 today.

http://www.aapodx2.com/2014/20141219.html

It is not my favourite one but it is my first AAPOD2 and i am pretty happy with it.

Have a nice day.

Thanks for the suggestion -- I do not have MaximDL and have decided to go the SGP, PixInsight route.  I realized that AT also has a 32 bit version.  I installed it and seem to be able to connect to the camera --of course, I have to wait until I see clear sky to know all is well, but it looks like it will work.  It is certainly unfortunate to have to use a 32bit version of AT rather than the 64bit version, but people have suggested that I will not be too disadvantaged using the 32bit version.    I so thought 32bit was a thing of the distant past (I'm not of the Windows world, just force there recently for AP stuff so I'm used to living in the 64bit Linux and OSX worlds) Hopefully, QHY will fix their drive so it can interface with 64bit programs soon!

AstroTortilla generally uses either MaximDL or Nebulosity to control the camera. Perhaps you can try one of these?

I have a new QHY23 and am totally new to the world of AP and Windows 7 so I may well be committing some rookie mistake.
All drivers, ASCOM and QHY, are the most recent versions.
I have attached the camera successfully to Sequence Generator Pro (trial) and captured darks - no problems
I can operate the camera with EZCAP.
Today I downloaded and installed AstroTortilla.
When I try to connect the QHY23, I see it in the ASCOM camera selector, but when I select it it complains and refuses to connect to the camera.
I am typing this on another computer so the error message may be slightly paraphrased.
It said:
Incompatible driver ASCOM.QHY23.Camera.  This 64bit capable driver is only registered as a 32 bit com driver

Help!

Hello,
 at the program start up it asks to chose a type of camera, If I select QHY It does not recognize it, so I am not able to go further...

Have you tried reducing USB traffic in Firecapture (cog wheel icon)?

Hello,
 I tried both 2.3 and beta 2.4 versions of Firecapture with my QHY5-II mono but it has not been detected as native driver. The camera works well with other programs (EZcapture, PHD etc). What is wrong with my camera and Firecapture? I also tried WDM driver but it is almost unusable because it freezes whatever action you do with the camera.
I find Firecapture a very interesting program so I would ask you whether someone else has successfully used it with this model of camera.

Thanks in advance,

Here is what we believe is a composite image of Uranus with four of its moons. The outermost and brightest is Titania, next, close in to the planet, is Miranda. On the opposite side are Ariel (closest) followed by Umbriel. Positions derived from the Sky & Telescope javascipt 'Uranian Moons' .(http://www.skyandtelescope.com/wp-content/observing-tools/uranus_moons/uranian.html)

Very difficult to image the moons (around 12-13th magnitude at best) without overexposing the planet into a bloated bright blob. As such this is a composite of two separate photos: one of the moons and one of only the planet itself.

Imaging train and specs:

8" refractor @ f/12. QHY5L-II mono. Seeing decent, 7/10, degrading to variable - it began to get cloudy during the full disc imaging run. The date and time: December 16th @ 00:14 UT.

For the moons, the QHY gain was 88% and the exposure was 5 seconds. The camera was set for 'Long Exposure Mode'. The moon image is a stack of 65 of these frames, with a dark frame applied.

For the planet, the QHY gain was 27.8 and the exposure was 100 ms (0.1 seconds). A stack of roughly 1000 frames.

Note that during capture in EZPlanetary, the histogram for the 'moons' exposures is a blown out spike where the planet sits and that the moon data barely, if at all, spikes out of the noise level. This is a result of the very high gain and long exposure time. During the 'planet' exposure, the histogram is much more representative of the kind seen during normal (i.e. Mars, Jupiter, or Saturn) planetary imaging.

The moons will stack out in Registax, and further processing with the wavelets will sharpen their discs. Photoshop does the rest in creating the composite.

It is interesting to note that WinJupos provided a close, but not exact match to the Sky & Telescope javascipt. However, I am one version out of date on WinJupos, and the S & T script is expiring on 31 December after being implemented on 1 December 2008. I wonder if the S & T script is getting inaccurate?

Technology Question and Answer / Re: flash firmware to convert Orion to QHY?

Hi,

You can do the QHY-5, but I'm not sure about the QHY5L-II, but I don't see why not.
You will need to talk to QHY using the Help Ticket.

Software Release and Development / Re: Weird EZCAP issue

Hi,

Making the system font smaller appears to have worked, the EZCAP GUI looks normal now and I can see all of the panels on the left.

Windows is so annoying!

Thanks
Craig
