Quote:I would like to suggest you consider the QHY9M monochrome CCD which has the same KAF8300 chip as the SBIG 8300M. For several reasons. First of all it offers superior cooling with a -50C below ambient, secondly it weighs in much lighter at just a touch over 1.1 pounds. It also has a considerable price point, for $2,099.00 a 5 position filter wheel is included.
Quote:8300M bar none; not that simple though. Lot of choices in 8300M, read more here.... Thx
Quote:Do you already have a guiding set up or do you need that as well? Just thinking of what else you might want to add to your purchases. Yep, the Atik is a great camera, and I have never owned one of the larger chip cameras so I won't chime in on which is the best.

Quote:I had the Atik 383L+ OSC and color. They are good cameras but the ones that I had were extremely picky about power supply. If the voltage was close to 12V the camera generated noise and once I had to throw away an entire night of subs. I learned that I had to supply ~13.5 volts in order to keep the images clean. After that experience every time I used the 383 I was worried that I would have to discard all my subs.
Quote:Warren, I do have a guiding setup... SSAG with a 50mm guidescope, just like yours. You know, your astrobin is the main reason why the 314L+ is even in the running, because your images are so amazing, with many of them from the exact same OTA I have.

Quote:Looking at the QHY9M it states on their website that the 2" filter wheel with RGB filters are only included as a part of a special deal available until March of 2010.

Quote:The Atik 428EX was on my list of contenders, and has the ICX674, which is the little brother of the ICX694. I'm pretty sure the only difference is half the resolution. I thought about that one too, but it's $2100 without a filter wheel. The Atik 460EX has the ICX694, but it's way outside my budget at $2900.Again, being a Sony chip might be worth it, especially since I really don't *need* a color wheel for a while. If I get a camera at the max of my budget, an Ha filter is all I will have for a while so I can just leave it on all the time.You know, I can't help but to slightly consider the Atik 420. It's has the smallest pixels and the smallest FOV at 50x38 with my refractor, but it's also only $1100 at nearly 2 megapixel with set point cooling to -30C. I could bank the savings and get some CCD experience under my belt with the 420, and then maybe next spring move on to something bigger and better.Too many choices.
If you really want to start out inexpensive, look for a used DSI III Pro mono, it is the exact same chip as the Atik314L+ but without cooling. That was what I started out with and actually learned about darks from!

Quote:But as you have the DSLR experience, you may already have some good processing experience, so, a better ccd may be preferable.
Quote:Main problem for "new" astrophotographers is that they don't really know what level of AP they want or if they really even want to persue AP as serious hobby. I know from personal experience. If one wants to just shoot some quick pictures with minimal personal engagement and without intent to upgrade AP equipment then some low end camera is perfect. But, if one intentions are more serious about AP then low end (or OSC) camera is waste of money and time. IMHO

Quote:1) if you want to do mono narrowband then I think a Sony 694 is best. You need all the sensitivity and QE you can get. An OSC is a waste of money.2) what mount do you have? Doing long exposure narrowband is all well and good, but the mount has to he up to it3) another option is to go fast. Powernewt or hyper star. You still will need a good camera but the mount requirements will be relaxed.4) large diffuse nebula or planetaries? The latter are small and bright, hence don't need long exposures or high sensitivity. They do need long focal length. I.e. you'll need a long scope and a great mount.

Quote:I'm actually really considering the Atik 420 now. It's just over a grand and uses the sony 274 chip with -30C set point cooling and fairly good numbers. I could bank the rest of my money and save it for a 694 camera while cutting my teeth with this one. I don't know though. Wow, never thought deciding would be so tough. I just wish I could find someone that has the Atik 420 to get their opinion. It seems like on one has it. Maybe that's a sign.
Quote:After 2-3 years with self-moded and uncooled Canon 1000D DSLR i decided to buy Atik 420m camera. Its about half year i bought this camera and due bad weather (like every winter in cz) i did only 2 test images with this camera.Im really satisfied with this camera despite the fact that this camera has really small chip. Its only about choosing right scope to shoot with (some short focal lenght refractors). Calibration of light frames is ridicuously simple in comparsion with DSLR data. Hotpixel map, bias and flat frames is all you need, with chip cooled to -10C (there is no reason to get lower like with other cameras). I can only recommend this camera, if you can live with its small chip, you will be more than satisfied Imho small chip got some advantages to big ones ... 1,25" filters are much cheaper than 2", small chip is less exacting on quality of optics. Like we say in czech republic: even with small clown you can make big show
