A reprocess.
This is a composite image comprising 8-hours of 20-minute subs taken last night on the Canon 200mm prime lenses, together with a 32-hour 2-framer taken on a single Sky90 including Ha and OIII narrowband data. It still needs a LOT … Continue reading
I had my first imaging session of the new season on the array last night using the 200mm lenses and the ASI 2600MC Pro CMOS cameras. The bright star Sadr sits in the centre and it also sits with … Continue reading

Once you bring Russ Croman’s Star XTerminator into your processing, there’s about a million different ways to go forward. Here’s yet another way.
