16-bit CCD camera
Hi there !!
I am abbasi Gandhi and I am working in Department of Physics in University of Limerick, Ireland. I am looking for a Peltier-cooled 16-bit resolution CCD camera (the type used by astronomers) with a shutter-open time (time to acquire image) of 1 to 20 seconds for my reseach work on Magneto optical kerr microscope. I shall appreciate it if someone can give me good advice on what to buy. Budget is limited as usual but any advice is welcome. Thanks, Abbasi Gandhi |

Also, what actual bit-depth do you need? True 16-bit cameras are very rare- probably non-existent except as custom built units (and correspondingly expensive). Most amateur and semi-amateur astronomical CCD cameras are around 13 bits. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

thanks for your answer.
I need least 512 x 512 pixels. I have bought " Meade Sky Imager" and trying to see the kerr rotation with my magnetic sample by applying meagntic field (Kerr effect) But I am not getting any result. One researcher suggested me SpectraSource HPC-1 CCD (512 X 512 pixels, 16-bit resolution, TK512 chip I think) camera as he worked on which I am working. But unfortunatly, this camera is not available in the market. can you suggest me any of those kind of cameras? if possible. Thanks agian for your interest. Abbasi |

Abbasi I'd take a look at the products made by SBIG (www.sbig.com) and Starlight Express (www.starlight-xpress.co.uk). Something like an SBIG ST-7i or Starlight Express HX516 or MX916 would probably work great. These run US$1000-1500 new, or you can look for used ones on Astromart (www.astromart.com). These cameras use 16-bit A/D conversion and have true dynamic ranges better than 13 bits. They are cooled to reduce noise and will give much better performance than the Meade imager you are trying to use. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

If the budget is tight and you don't mind a bit of simple construction, this camera with one of the smaller CCDs might fit the bill http://www.artemisccd.co.uk/ Robin |

Thanks, Abbasi Gandhi http://www.optcorp.com/ProductList.aspx?uid=319-320-323 The SAC8 is a Peltier-cooled B&W CCD camera with a pixel display of 640 X 480 and a pixel size of 9.6 X 7.5 microns. Can do color imaging with the addition of optional color filter wheel. Cost is about $400.00. It can be adapted for microscopic work (in fact, I believe it comes with the adapter). |

Or since he is in the UK the small ads in Astronomy Now and online whatever AstroAds is called thise week. Maybe be better for a university to buy one new though since they may need some technical support to get it to do exactly what they want for calibrated quantitative work. HX516 is probably the cheapest one available in the UK that might work. Regards, Martin Brown |

Only 8 bit though with poor flat field and linearity. A very sensive astro camera but not good for quantitative work IMO.

I use my cannon digital rebel for all my photography work now. Its a great camera. That might be something he could look into. |
