The Cygnus wall

[Brian28]

Taken over the last few nights here on sunny Canvey Island 🌴😂..

3 hours of 600 sec exposures , once again Ha & OIII using Chroma 3nm filters in my QSI583.

had trouble trying to cool the camera , could only get it down to -15 instead of the -20 , but it doesn't appear to have caused an issue .

the nice clear skies also gave me some of the best guiding I've had ..

That's very nice.  I like that.  -15 and -20 won't make any difference.

Hi , thanks for the comment ..👍

It was quite warm during the night When I was taking this shot and The camera wouldn't go below -15 and I was unsure about the effect the temperature would have . I was considering water cooling , but as it didn't seem to have a detrimental effect I probably won't bother ..
