Having successfully obtained focus with the QHY10/Equinox 80/TS OAG-flip mirror, I was then able to also obtain my first “proper” image of a celestial object using the QHY10 camera.
The extensive cloud cover meant that the only object available was the full Moon which was able to penetrate the clouds. To photograph this, I had to use the lowest shutter speed setting possible of 1/10000 second and also using an aperture mask to reduce the aperture of the Equinox 80mm OTA by about 70% and the clouds further reduced the brightness of the Moon!! I don’t think the QHY10 was designed with the brightness of the Moon in mind. Settings on Nebulosity were also amp off on the QHY10, gain 0, offset 130.
Focus point = 15.5mm on the scale on the Equinox 80mm for the QHY10 with the TS OAG/Flip mirror also in place.
The following screenshot shows the focused Moon in Nebulosity 4 software, together with settings for the QHY10 on that software used tonight – note that there is colour dispersion due I suspect to low altitude of Moon and cloud present:
I found a process to address the colour dispersion using GIMP2 software using the decompose function which I have described in another post (click on link below) – please could readers let me know of any better process that you are aware of that I could have used tonight. I do have an atmospheric dispersion corrector but it is only 1.25″ fitting rather than the 2″ fitting required for the QHY10 camera.
This resulted in my successful image of the Moon:
