Description

Hi folks!

Finally i get a decent guide camera! The QHY 5L-II-M seems to work perfectly. I was reading in astro forums that some people had have a lot of problem using this camera and for half is true but the problem is the power suppling. A lot of notebook and even Raspberry PI does not have a good USB 5V and the solution is to get a powered USB hub...It was enough just seeing the brightness of status led to know that there was somethings wrong... Solved in less of a minute!

I used till yesterday a modded webcam with aptina AR0130 sensor but maximum exposition time was 1/5 seconds using stacking, this is good for fast telescopes but when you use a primary scope with long focal lenght it could be problematic...

Data of this image are taken in a very poor seeing night with not a perfect polar alignment and there were a lot of veils and clouds: nights just for testing purpose.

Im still waiting for a dark night, I don't wanna do more tests!!!

God please blow from south and give us African Anticyclone!

God bless you all for your prayers astro friends! :-)
