Good question! Well cameras like the QHY8pro use the same sensor, and are still worth a lot of money (new or on the second hand market).. Which is because you can still take excellent shots with the sensor. I'd say that you really need cooling for this project to be worthwhile. Otherwise, you should just astromod a DSLR instead. I'd say that M42 probably isn't the best target for comparison shots - its such a bright target that it doesn't need very long exposure times and wont benefit as much from cooling.. as you say, a DSLR should be able to take quite comparable shots. CCDs have more read noise than modern CMOS sensors, so they will be at a disadvantage on bright targets for which you take lots of shorter exposures. 

In general though I'm of the opinion that astrophotography will switch completely over to CMOS. I'd like to see a DIY CMOS camera using a modern CMOS sensor. In theory, it could be less hassle as you wouldn't have to worry about analogue-to-digital conversion (and its associated noise issues). 

 

If you need anything do ask. I do have spare PCBs I'm happy to send out (for free)

Do you still have some PCBs? I am very interested in the CAM86

@abhoriel, hi I tried to assemble the CAM84 and had some issues with it. I am very interessted on the new 86. What does the Atmel-processor do? Only cooling or also readout?

Do you still have some spare PCBs?
