Yeah but ..how many frames would you need..were talking about a larger sensor gathering more photons..most are using a 1/3 rd sensor. .my dvr I think pulls 25fps so I drop 10 fps but using a 2/3 sensor I would imagine would compensate..if im looking at this the correct way...and if it was fitted to a fast scope mmm gets a bit confusing..the software may end be the make or break for using such a camera..they have this make on ebay not this model..as a planetery camera. .

The sony sensor is used in a lot of astronomy cameras..very sensitive so its documented.

Day off today..carol took a bad allergic reaction to something 80% of her in weal rashes..in hospital ..so time to read.. these cameras have a global shutter and very sensitive ..the global shutter captures the full frame at one go compared to a rolling shutter which does a progressive capture .the image I saw showing the difference was a helicopter the rotor blades were more bent backwards..so camera wise we should be looking at global shutter to stop bending affect of our images..look up the basler site and check out the chips they use..and check against astrophotography cameras..to me they are using these chips through long exposure to capture there single image and doing this via software manipulation. .we in my opinion could use them as av cams the only prob ..is the software can it be used for av..one cam on a 2/3 sensor can do 5 sec exposure..now with a global shutter it makes me wonder how good is the image av wise

www.baslerweb.com/en/products/area-scan-cameras/ace/aca2500-60umniryou can get a free download of the software for there cameras..will try this tonight.. im not going to say this will be cheap or it will work..its a wee project..learning curve.. my thoughts on this is. bigger sensor=more photons captured faster ,bigger field if view. global shutter= no image distortion via bending usb 3= faster data transfer pc software to control camera settings I look at the lodestar live and its reverse engineering to make it a video camera...this basler type camera may be the opposite side of the lodestar live idea. can somebody else confirm this or am I just a nut case...

The 2/3rd cam in the first link is almost the same as a DMK41. Great for solar, ok for planetary. Give it a miss for dso. You don't have to worry about the bending effect you noticed. It only effects fast moving things. Stars, planets and dso's don't move much. Pixel size in both cams are smallish so would need longer exposures for dso. I tried my DMK's on dso..........not terrible, but not great either. My DMK31 is brilliant for solar and lunar though, but there are cheaper options.

Cheers allan..ive only used the sammy and pd1..new territory for me..was the biiger chip that caught my eye..then I saw it was used in some astrophotography cams..will keep looking .. did you check there site out..
