it has a built in mask to reduce reflections (the Proline may as well - not sure).
Yep they sure do, standard now I think? Since upgrading to the new low reflection Astronomiks filter set though it appears I won't need the mask upgarde as I haven't seen any internal refections in all 10 images since the filter upgarde (touch wood).

the extra cooling that is fast that was the main selling point for me as I want -35C all year round and I should be able to do that with the Proline.
Greg.
It's great, I have been able to use -35C every single imaging sesssion now for over two years. I don't think a 75 delta C is necessary unless you live somwhere that is regularly hotter than +25C at night and even then you could just go to a blisteringly warm... -30C instead .
