Hi Brendan,
Gets to 30'c below ambient as reported by the camera, but Central DS say the actual CMOS chip is 5 - 7 degrees cooler again so I estimate on a 25'c evening it is running at about -10 to -15 'C.
I did a comparison between my CDS-600D and EOS 600D camera here:
http://www.astrophotography.id.au/ce...me-comparison/ when I got the camera as it was raining and had to play with my new toy.
I agree lower subs are needed but didn't realise at the time how much more sensitive this camera was over my std camera so will learn from this.
I hope that answers your questions
Cheers
Anthony

What temp does it run down to?...Noise wise looks very clean, good detail and colour! The only thing is 300s subs start to bloat stars and washout star saturation colour ...it's just the nature of longer subs.
I suspect you might be able to get away with 240s subs (or less) ...stack lots for a good SNR and be just as good as 300s.
But I repeat only 2 subs @300s...pretty good Indeed!  |
