First light QHY10 single shot colour camera 15/6/2019 & determining the focus point on Vernier scale on Equinox Pro 80mm for QHY10

Pointed at window on distant house (curtains closed so no peeping but does have light behind it to give some contrast & help me to find focus point on Sky Watcher Equinox Pro 80mm telescope!).

I was surprised how long the exposures needed to be to get bright image – although less bright images could be manipulated in GIMP2 but using curves to bring out detail.

The size of the senor is large – three fourths (slightly larger than APS) giving enormous image compared to tiny sensors I have used in past, but clearly less sensitive than for example my QHY6 camera.

What I don’t understand tonight is that the images appear to be monochrome on a single shot colour camera – I can’t see setting in the software to make the images colour……I think I can sort this tomorrow by taking image during day when clearly colour around. Perhaps I am saving the images in wrong format or exposure not long enough to obtain colour data?

Tonight the focus point for the QHY10 camera on the Sky Watcher Equinox Pro 80mm with the nosepiece & Altair self centring 35mm extension tube that came with the camera & my own additional 50mm extension tube was 44mm on the Vernier scale on the Equinox’s focus tube – note this is likely to be slightly longer than will be needed for sky as the window below is closer than the sky which drives the focus point further out from the telescope.


Oringal image = 3896 x 2612 pixels, 10 second exposure using Nebulosity 4 software & selecting Nebulosity’s own in-built driver for QHY10 camera (below):

Above image cropped = this image looks like it has colour data but I think this might be artificial from my playing around with GIMP…..

The following image was taken using EZCAP_QT (recommended by QHY for this camera) – just under 4 seconds exposure with increased gain:

Image 2 – 60secs on Nebulosity 4 – as far as I can tell this is saved as B&W image:
