ASI Cameras

What is better than an ASI camera? 

The answer is two of them!  I got myself an ASI 120MM and an ASI 120MC, the monochromatic model is for solar and lunar imaging, while the color one is for planets.  Frankly, with only a C5 as my biggest telescope, I believe that I will let the color one go soon.  But anyway, why not give a trial?  I had success with a DBK and a C5, so I'm pretty confident that the ASI will do the job nicely as well.

The general impression is excellent.

Packaging is simple but works.  It comes with a lens, a 1.25" nosepiece, a driver CD, a very nice USB cable, and you even get a ST4 cable!

Installation is SUPER EASY as mentioned in the user guide.

The software is easy to use, too.


The software and the driver are rather stable, but this is only my first impression.  Sharpcap is easy to use and pretty powerful.

I've to update my Registax 5 to the latest release to support the Mono8 codec, RGB24 is fine as expected, no need to upgrade.

These were pretty dark, I have to use very high gain and relatively long exposure (~1s) to get images like the above.  Not bad, I would say.  Not a huge improvement over my Lumenera nor DMK, but I should test again with astronomical targets.

These two cameras were again close to par-focal with my Japanese Widescan 20mm Type III, nice plus.

Expect better sky next week.
