Hi all thanks for all the kind words and encouragement. I thoroughly enjoy this project, albeit it really test my patience at times and putting it together and making it works takes a lot of trial and error. The whole gist of cooling the camera is to turn it into a capable narrowband imager. Below is a stack of 5x12 min exp with 7nm H-alpha filter, this is only possible with some forms of cooling to the camera :

Is this a modified or non-modified cam? (as far as the low pass filter is concerned)
