Wishing well on a short exposure - camera testing.

Post by si-cho »

I have here another short time imaging, now on the Wishing Well open cluster and its neighbour open clusters. I was testing the control of SharCap on a QHY Camera. The main issue is that QHY cameras seems not to have a smooth temperatures control, so I was trying to lower and then rise the temperature slowly, in a time span of 3 to 4 minutes.
The image was taken using the WO SpaceCat, on february 19th.
Camera QHY183c
40 images of 30 seconds
Temperature -5C
Mount iOptron SkyGuider Pro with iPolar
Later stacking using DSS, processing using PxI and GIMP.
So far I am using also from SharpCap the Live Stack and Quick Capture system (I just stop them when I needed), and also the Flat assistant, which is really useful.

Another nice image and wide field of view especially for the 20 min integration time, always fascinating to see how many stars are out there as from my location with the naked eye you do not see many.

Cheers

Thanks Nick, I do enjoy very much wide field images, as you said, the stars are amazing, in colours, formations and many more. Also I noticed that quite often, open clusters are in company of nice colourful background, maybe because they are mostly residing within the galactic disc. Groups of open clusters are my favourite targets for these images.
