RE: [ccd-newastro] Pixinsight trial version Internet bandwidth?
I'm in the same process (but without usage limitations; finally got DSL to
my version of the boonies).
I noticed nothing in the way of internet use by the program each time I
But I did, alas, notice how very complex it is to do anything with this

Subject: [ccd-newastro] Pixinsight trial version Internet bandwidth?
Given the favorable comments here about Pixinsight, I'm considering
downloading the 45-day trial version. However, the website says the trial
version needs an Internet connection to operate.
My Internet access has a monthly usage limit, and I don't know what
Pixinsight uses the Internet for. If it's just a few KB to check something,
that's fine, but if it downloads large program modules each time it's
launched, that could be a problem. I've emailed the authors, but have
received no reply.
Does anyone know how much bandwidth the Pixinsight trial version uses?

I've been predicting this for a few years now. Once Sony has exited there will be few affordable CCDs (Kodak / Truesense). Most surviving CCD will be expensive small runs (E2V). There will be significantly different dynamics when the amateur astro-imaging manufacturers and community come to terms with CMOS.
Astro-cam manufacturers may face a threat/challenge from the big camera companies (Canon, Nikon, Sony, etc.). But they might be safe due to the miniscule astro-cam market combined with the inertia and indifference of the big companies. Canon and Nikon have produced half-hearted "astro" models that simply omit the IR filter with a significant price increase. But these are not likely to go anywhere - the Canon is dead and the Nikon may die soon. But the real saving grace for astro-cams will be mono (non-Bayer) cams, which remain infuriatingly unavailable for DSLR/MICL (except for one very expensive Leica).
Astro practitioners will face new sensor dynamics and adopt new imaging practices. CMOS has much less read noise and shallower full well capacity than CCD. Both of these characteristics favor significantly shorter sub-exps than CCD practitioners are accustomed to. This will permit unguided imaging as viable sub-exps of only a few seconds become feasible. This of course also means many more sub-exps, which in turn affects processing in many ways. I have been exploring these dynamics for some time now (via intensified imaging) and they are real game changers. It could be an exciting new horizon...
