Max exposure time is set to 30 sec on the Merrill sensor cams, but in "Extended Mode" it can go to 120 sec.
I have uses 30 for star fields w/o any great problem except ponce when the sky colour changed. Never could
figure out why. I was using ISO 400 at the time.

Often enough, you read the term "niche camera" in the reviews. It is usually not defined, and usually only put
in to suggest... who knows what? (Sometimes they say why they use the term with explanations.) However, most
times I think it suggests it's something to be avoided unless you're quirky. That's CARP, IMO. I have done lots with
mine, and the Quattros are supposed to have overcome some of the Merrill limitations.

I think it's a very good idea to talk to "that pro" and get to use the camera. Meanwhile, download and install the latest
SPP, and find some Quattro raws (even some H images are available - somewhere). SPP, Mac and Win versions, are here:

I will leave you to look for some Q-H raws.

FYI only, and when I can find it, I will provide a link to a moon shot with my Merrill. It's a 100% crop.

Will change the thread title as you asked...
