Hi Everyone.  I just purchased my first cooled dedicated CCD camera - the ATIK 414EX found here: https://www.highpoin...-camera-atk0137

 

I only found one discussion on past forums and the reviews were mixed.  I'm specifically curious how you all feel this camera would perform for Deep-Sky Imaging.  Did I make a decent choice?  Fyi - the price was right.

 

Also, it claims to run on 12volts and 1amp.  Can a cooled camera really run on 1 amp?  Doesn't that seem unlikely considering it has a mini-fridge attached to it?  So if this is the case, the extra draw on my portable power pack should be minimal.  Or am I missing something here?  Thoughts?

 

    Sensor Type: CCD - Sony ICX825
    Horizontal Resolution: 1392 pixels
    Vertical Resolution: 1040 pixels
    Pixel Size: 6.45 µM x 6.45 µM
    ADC: 16 bit
    Readout Noise: 5e- typical value
    Interface: Mini-USB 2.0 High Speed
    Power: 12v DC 1A
    Maximum Exposure Length: Unlimited
    Minimum Exposure Length: 1/1000 s
    Cooling: Thermoelectric set point with max ΔT=>-30°C
    Weight: .88 lb.
    Backfocus: 13mm

    Pixel Array & Resolution = 1392 x 1040 (1.4 MP)
    Sensor Dimensions (mm x mm) = 8.98 x 6.7

    Sensor Diagonal (mm) = 11.21

    Power = 12v/1amp

 

Thank you,

Tommy

You asked, right?  "specifically curious"  So you want an honest evaluation?  I'll risk it, with considerable trepidation.

 

The quality is fine, the read noise a bit high.  Pretty old design. 

 

But the main issue is that the small chip has a limited field of view.   For $1000 you can get an ASI294MCPro CMOS camera with a much larger chip.  A modern design with low read noise. So that's what people do these days, which is likely why you found it hard to find reviews.

 

Any chance Highpoint would exchange it for an ASI294MCPro?  If not, you can make excellent quality images with the 414, I have a 460, similar quality camera with a chip size in between the 414 and the 294.  The FOV will be small.

Lol, this is exactly what I was looking for. I bought it used for $500.00 (that's why I couldn't resist).

Since it's my first dedicated camera, I'll use it to learn (should be fine for galaxy season). But I will start looking for a used upgrade.

Thank you!

Any thoughts about it only drawing 1 amp?

Whew.  Sigh of relief.  I was afraid I'd p### you off.

Depends a great deal about how far below ambient you want to cool.  Here's another camera.  The point is the extreme non-linearity.  It takes 1.75 amps to cool it down maybe 44 degrees and 0.25A to cool it down 22.

I wouldn't worry about it, if that's what the spec sheet says it's probably close. Picking a power supply with a little more current capacity wouldn't hurt if you're concerned.

This is great to hear.  I was sure these cooled cameras would draw much more power and force me to upgrade my power-0pak again.  Thanks guys.

 

So I see a ASI1600MM Pro (seems to be popular).  Is this a higher-end or lower-end model to the ASI294MCPro?

 

Thanks.

Oh, never mind, I just saw that the ASI1600MM Pro is Monochrome.   I'll pass.  I want to stick to one shot color for now.
