2600MC Cooling
I haven’t used my 3 year old 2600MC for 5months since recently acquiring my new 2600MM.In an attempt to capture a comprehensive Dark Library, the 2600MC had difficulty cooling down to my normal -10C. It gets to -9.6 at 99% power and when you start taking short exposure darks (60 sec) the temperature starts going up progressively to -8.5 then -8.0 then settles around - 7.9 C. at 100% power. It’s obviously struggling
So I swapped cameras and set up the newish 2600MM and it cooled down very efficiently to -10.1C at 83% power and maintained that temperature whilst taking short darks.
Outside temperature was 22deg and humidity was 90%
I have no prior experience with these ZWO CMOS coolers so I’m guessing the 3 year old 2600MC cooler is functioning but running inefficiently.
When I last used my 2600MC back in May the outside temperature was quite cool heading towards Winter and it was operating fine at -10C.
It’s obviously struggling now as the cooler on the 2600MC is working but not efficient and is out of warranty so any replacement parts or servicing would be at time and cost.
I welcome any comments, advice or similar experiences with ZWO cooling.
Cheers
Martin
