Hi Ken
The detail in M104 in your re-processed image is gorgeous. I also note that it is down sized from the original, which showed excellent auto guiding – nice round stars, especially at an fl of around 2000mm.
I’m intrigued by the lack of blooming in your images! I was shooting 5 min subs at F9.6 and you were shooting 4 min subs at F5, around 2 photographic stops faster! I guess it’s because my model ST7 doesn’t have anti-blooming gate technology, whereas the QHY8 must have anti-blooming implemented?
I’ll have to have a good, close look at the QHY8 as I’m looking to upgrade to a bigger chip than the 765x510 pixel ST7.
Cheers
Dennis
