large FF-MF sensor MILC for large Deep Sky Objects

CMos FF-MF MILC is way Better in very Low Light conditions than CCD based Astro Professional cameras from 1990-2014, despite they were worth hundreds of-thousands of Dollars. Actual FF-MF CMOS sensor runs 10 times Cooler than those big CCDs. Then, it has little need for a sophisticated Cooling System. BSI Technology plus Micro Lenses ensure similar Yields of Electrons- generated per incident Photons, QE, at least in the Visible Spectrum. Dark Current levels have been divided by thousands v CCD. Read Noise and Electronic Noise have been considerably reduced since CCD times. CMos gains Noise Cancelation at Pixel level & Digitize their Signal directly on chip so that it can be Pushed much more than the one from CCDs : " www.company7.com/sbig/products/st4.html "
From '90 to 2010, 20 years of Electronic Revolution :
1990s CCD sensor compared to 2010s CMOS (BSI) one :
Signal is now Cleaned + Digitized " on chip " = the Exmor Bonus !

To avoid overheating a CMOS FF-MF MILC, it can record its Raw files via USB 3.2-gen2 to an External SSD even at very high frame rates. In case, you can buy optional Cooler Fan to put at the FF-MF MILC's back. Good news you no longer have to wait until Christmas, New Year's Days to keep the Magnificent Colors of Magical Nights. What are you waiting for to challenge long exposure DSO Astro Photography w/ hundreds of Short Exposures of 1 second each ?
Then, no longer need for :
-1. Super rigid EQuatorial Mount.
-2. Very precise Alignment to the Polar Star.
-3. Very precise and finely Calibrated Guiding System.
As long as you can track, even manually, just to keep the Deep Sky object target into the camera's field of view. Come on. I'm going to help you take the plunge by showing you what you could already achieve with long exposures and Very Little Equipment. Pentax K5 or Q10 and Samsung NX-mini on Skywatcher 200/1000, then 254/1200 on a Black HEQ5 Mount. A Goto Kit later and a WebCam on the finderscope for Guiding via PhD. Knowing that by limiting your Exposures to ~1 sec. you'll easily get images 4x Sharper than mine. Using Actual FF-MF MILC, you'll easily get Better Colors than mine. One Bad: they can't Record Cropped Raw's ROI. Couldn't this be done by SW to FITS files: write to FITS files the ROI from Raws inside a FF, APSH/c, 4/3, 1" delimiter you'll move over the full MFc ?
ROI: acronym for Region of Interest, cropping tool in CMos Astro Cams drivers.
