First test on JAI CVM50-IR B/W camera (IR for infrared).
thanks to "Image S S.r.l." for camera lend
I apologize for my bad English.
Jai CVM50-IR video camera is a B/W industrial CCD camera with some good features.
- High sensitivity 0.05 Lux declared from JAI.
- Manual Gain
- Manual shutter from 1/50 to 1/10.000 sec.
- Possibility to grab interlaced sequence and field (duplicate a field) sequence.
- Fast download time (50/60 Field x Sec and 25/30 Interlaced Frame Pal or Ntsc).
- Easy to setup focus on telescope thanks to high frame rate and high luminosity and more other features.
I think that this is a good video camera for planetary image in congiuction to a decent frame grabber (I use a pinnacle PC/SAT card), because is possible to get a lots of frames in a bit. The Signal/Noise ratio is much better than a webcam and, when stacking of sequence, is possible to reach a good dynamic.
Of course a professional camera 3CCD with a dedicated PC interface that free images from flickering and exposure limit can take better color images in one shot.
Above i show you what easy alignement and sum can do with BAD images. Iris 3.53 was used
Tomorrow if a seeing will be good i'll show other tests... i hope.
Left images show 400 frames stacked, right images show one of 400 frames sequence (random frame).
