living the same city as you do, i would say that your fears are unfounded. sensor overheating happens under more extreme conditions. in fact, if you really have to worry about something, worry about the fact that during this time, winter is approaching, and with that heem. so worry about the condensation on your equipments which will be left in the open atmosphere.


I’ve only noticed objectionable sensor noise when the temperature goes above about 90 deg. F., or 32 deg. C.

Dark frame subtraction works wonders. In my camera, it is called Long Exposure noise reduction. You can also do this yourself by taking a long exposure with the lens cap on, and then subtracting the dark frame from the regular photo using Photoshop. Not sure if other softwares will support this though.
