This camera looks great except for its relatively high noise, and about 63dB dynamic range. Do you have any other long exposure pictures that you have taken with this camera?
Kind regards,

Hi Laurence,
I am sorry I missed your message, the noise is not too bad at constant -15. The camera cools to -30 below ambient temperature. Depending on your location and season you might be able to push lower like -20. I won’t recommend anything lower then -20, might damage the sensor or frost it. I will need to find some subs I captured at 20 minutes. If I can’t find any, I will try to capture a osc of some random target if the weather and seeing is good. Besides the lagoon I captured was with 80% or 70% moon glow therefore losing a lot of details in the outer rims. Equipment was 110ed refractor with a focal reducer/ flattener
Hope this helps and do reply me if you are still interested so I can bring the ccd out for my next imaging session.
Regards,
Girit
