Description

Another test image, this time with Ha 7nm filter.
Since a few days we have hier really high temperatures, daytime 34-35 C°, in the night 25C° and pretty high humidity. My DIY cooling on the ASI 174mm works hard, but it could not sink the sensor temp below 12 C° :-)

Update : Now I collected additionally 1 hour Oiii data.
Filter Optolong OIII 12nm 2".
This is my very first try to process nb data to a bicolor image :-)
